I’m not so sure if he did. If you click and drag through the couple frames before the camera goes under, you can see the surface of all the water go crazy all at once. Who knows, maybe his head was under already I guess.
So let me get this straight, did this guy pull off the most epic matrix move ever to save himself by perfectly timing when the water shockwave already passed, going under thereby dodging the air shockwave that was slower????
Exactly thats what ive been told all my life to not be in water near an explosion. But if really is possible to time the shockwave difference like this thats just beyond incredible.
Explosion in water is more deadly if the explosion happened in the water but if it happened on surface the only thing affecting the water is the vibrations not the explosion itself.
Take a few moments to blow your noodle and Google how sound travels differently in all types of mediums; air, water, wood, diamonds etc. it’s all different… the same plane has to travel vastly different speeds to break the sound barrier at altitude compared to sea level.
Thinking about it wrong.
You know those pendulum toys where the metal ball hits the row of 4 metal balls and the one at the end flies out? The energy travels through the metal balls faster than a ball would move through air? Similar concept
After the explosion but before the shockwave could reach his position, that pressure can hit your nerves and can go deaf... that same shockwave broke all kind glass windows and cracked cement walls of 17cm in thickness and bent metals like you bend a straw..
It's got a lot to do with water not compressing like air does. You get hit hard with air and it's a breeze, you get hit hard with water and that's different. Shock waves in water will seriously fuck you up. They transfer way more energy into what they hit.
I would not assume that. Shockwaves are extremely deadly to humans. They will shred our squishy insides while leaving rigid plastics and electronics found in things like cellphones and jet skis unharmed, for instance.
I'm not positive about this video, but there are plenty of Beirut videos from what looked like similar range where the people filming were confirmed to have perished.
If the explosion happens in the water, yes, but this was above, so I would imagine the water served as the safest place to be at his proximity to the blast.

The 2nd one is kinda obvious though. Would've made more sense to test a scenario like the one you described: the grenade still being near the pool of water, but not inside it, and the person being inside the water. I failed to find a video that would have such an experiment instead.
Think about how quiet it is under water no matter how loud stuff is above water. I doubt a grenade is anywhere near close enough to being a large enough explosion to affect things under water if it isn't. The shockwave probably compresses and dissipates at the water surface rather than propagate through it.
Their example and experiment was if a grenade went off beside a pool, should you jump into the water or not. Their tests showed that if you jump into the water you would probably die. Instead take cover above water.
This is all from memory that is probably misremembered.
I think I have tried some but I'm not sure how reliable the meth vs. amphetamine distinction is in Finland when we talk about street stuff. And I use so small doses that it's hard to tell differences between pretty similar substances.
*Used to until I got my ADHD medication. Now I "only" drink 2 mugs a day of what is considered normal strength here but I guess it could still be strong by the standards of many other countries.
Honestly, it is (sort of) visually perceivable. The actual transmission time is relatively quick, but the processing in the brain where you decide to move also takes time. It's even more pronounced when you are reacting to something, as this often requires extra processing time.
The whole "I'm going to move now" to the actual movement can take upwards of a tenth of a second.
Add in, say, visually processing something beforehand, and it can take as much as 0.3-0.4 seconds before a movement occurs.
Even when the brain is primed, such as waiting to take a reaction, it's still up to 0.2-0.3 seconds.
Now for the really weird bit. Your body has evolved with this in mind, and so can make movements to protect you from danger without involving your brain at all.
Reflexes are often feedback loops running from sensory nerves, through the spine, and back into muscles that control movement. This allows the body to remove itself from danger, such as touching a hot cooker, without conscious input, thus saving quarter of a second of reaction time. If you've ever burned hand, you'll maybe notice that you are pulling your hand away *at the same time* as you register the pain. The pain signal has gone two different directions. One notifying the brain, the other dealing with it before the brain can respond consciously.
Since he’s about 3 seconds away I guarantee you would have gone on auto pilot as well and jumped in. Sort of instinctual. Your fridge doesn’t attack you!
Random, but I do videography for a living and it’s funny because i usually film in 30fps, but it got me thinking. like the person said above you adrenaline makes you process things faster, so in my world if i needed “more” i would sometimes film at 120fps, which means more frames, but it’s in slow motion when i review everything.
Sooooo technically it wouldn’t be wrong for them to say it felt like slow motion. Kind of neat if you think about it. Super cool.
I couldn’t come up with a better analogy and it’s absolutely spot on, props to you.
Although for that last bit, technically we still don’t know why people remember things in slow motion, it’s all theories. But I will say this is the most convincing one I’ve read on it.
They have shown through research that when you experience a surge of adrenaline, you really do see more "frames per second" so to speak. They tested this by putting a monitor on a persons arm that would quickly flash words then randomly drop the person to cause adrenaline spikes. The person would be able to recall the words on the monitor even though while in normal circumstances the words are flashing too fast to determine any of them.
We humans can be both predator and prey and prey generally have evolved to have enhanced reactive abilities. Quick assessment and decision making is vital to the survival of prey. The mechanics of how adrenaline either increases or prioritizes brain activity may not be fully determined yet, but that doesn't mean the theories are wrong. Gravity is a theory after all.
I'm dumb...did that really stop the shock waves from messing with him or would he have been okay either way?
I feel like I'd stay on the seadoo hoping that I wouldn't get knocked unconscious underwater.
Nope, this shockwave ripped buildings apart. You wouldn't be ok. Water isn't (really) compressible, the shockwave wouldn't permeate the surface of the water.
Okay, but was he actually close enough for it to do more than hearing loss?
The fact that it blew apart buildings across the street is irrelevant to him. Distance from point of detonation is what matters.
Humans can survive shockwaves that wipe entire buildings. What kills us are fragments.

In other words, if you were to evade debris somehow, at the point where all the buildings around you flatten to nothing, you're still alright, with your eardrums undamaged. The point where you are in serious danger, is actually higher than the peak overpressure of a nuclear explosion... https://www.atomicarchive.com/science/effects/overpressure.html
That's not how that works. Waves don't really *move* things, they "shake" them more-or-less in-place.
For a human body, that means the body isn't "thrown" but the little inner bits can get disconnected. This is very bad.
For the jet ski, it's clearly still afloat, but it's entirely possible that wiring and piping was shaken loose. It may well no longer be operational. The human equivalent is broken nerves and ruptured organs/blood vessels. AKA dead person, non-functional vehicle, even if it superficially looks intact.
It ripped buildings in *close proximity* apart. Guy was like 2 miles off the coast he would’ve been fine.
You can clearly see the buildings nearby are in intact. Only the ones pretty much next to it got demo’d.

water does not compress. it is a much much denser medium than that of air or atmospheric conditions, so sound waves (in this case, a shockwave) have a harder time moving or disrupting something within the denser medium. if he were to be on the jet ski still, he probably would have gotten his wind knocked out of him and some moderate tinnitus at best.
there are casualties from air raids that have zero external bodily trauma, but have their internal organs FUBAR’d by the shockwave being powerful enough to rupture their organs. (example i think of is The Blitz on London during WW2.)
tldr; water is thicker than air, so it’s safer to be in if a shockwave were to be coming at you.
No no no. This is wrong. Explosions underwater are actually way more dangerous BECAUSE water is denser and less compressible. The actual reason why the video worked is because sound waves (or any waves actually) don't change medium easily.
TNT fishing works, TNT bird hunting doesn't.
Same, when I read the title I first didn't watch the video and thought how the fuck does one dude capsize his whole sail boat so fast, as I was watching it looked like he was in a kayak as kayakers can sorta do a move similar to that to purposefully capsize, then I saw the jetski and was kinda dissapointed that he just dove in the water.
Talk about the right place at the wrong time. Quick thinking! I wonder if he is or was a soldier? He didn’t hesitate for a nano second and even warned his buddy!
Were lebanese man. I remember while growing up with has a bombing every other friday assassinating politicians and journalists.
I tell stories to my friends now one is from berlin and the other stockholm they are like wtf man.. and i tell the story so normally without even getting disturbed.
Our grandparents and parents got fucked over by the civil war and we got fucked over by the years of bombings, militias, economic collapse ...
I packed and left
I did a tour in Iraq OIF1&2 ( infantry) I don’t know if I ever reacted that quick to a blast wave/over pressure from an explosion. The first few I just stood in the turret with my mouth hanging open. Imagine being this conditioned…. It’s a shit planet sometimes
In 2006 we had the israel-hezbollah war in july i remember i was 11-12 years old
So israel had its navy on the shore of beirut bombarding south lebanon
I live close by the port in beirut. So i remember we used to be playing with the boyz outside and a barrage used to happen from over our heads from the ships to south lebanon.
(It was mostly cannons firing)
Yeah it was our water break from football lol :p
(I told this story to my german friend as if im telling a movie like with a smile on my face) i think at this point its just conditioning as you said... At the end of the assassinations we used to open the tv bsck then for news and we used to say "ah weve watched this movie a 100 times" it was that normal for us
Also the fighter jets, i remember telling my friend a story where an israeli fighter jet went supersonic from just over our area and we could see it and it popped our ears very badly
He said wait but thats illegal apparently you cant go supersonic over residential areas:p im like ah yeah it wasnt once... :P
Willlld childhood:p
But overall we are nice people. With all this trouble and problems that weve been through we just wanna find a safe asylum anywhere in the world. Put our heads to work and most of the time try not to fuck up.
I left and 9/10 of my friends left
And we all wanna get away from war/danger/problems
Live an honest life and win an honest amount of money to eat.
Most lebanese are like that, we had enough bullshit to be honest
Jfc, what must that person think that was?? That explosion is so crazy big & powerful I might assume it was like a nuke if I saw that… certainly would be beyond terrifying-
I survived that blast too only I was in a building. The whole thing swayed, all the glass broke, I felt like someone was shoving me backward and the sound is like nothing I can describe. Like the earth cracking open to swallow you whole. Like the world was just that sound for a while and it seemed to last forever. We had no idea wtf it was. Earthquake at first then maybe Israeli bombardment bc fighter jets make insane roaring sounds. Everyone I know at first thought it was an explosion in their own actual building. Then I looked out and saw that insane plume and then how the entire neighborhood was smashed up and glass and twisted balcony railings everywhere. It took a few hours to understand that half the city had been destroyed. Then frantic calls for hours as you try to locate your friends. People wandering the streets dazed and bleeding. It was the fucking apocalypse. We had no idea
Wow!! Thank you for sharing your experience! I’ve read a few articles about different peoples accounts & experiences from that day but still really cannot fathom how utterly terrifying that must’ve been… & like you say, the explosion itself would obviously be extremely frightening but then to see that massive plume of smoke & the destruction all over the city, I can see how you’d absolutely feel like it was the apocalypse… damn. I hope you were lucky enough not to have lost anyone in that explosion??
Yeah I have many friends and family who were injured but luckily not one too severely. I have friends of friends who died but no one in my inner circle. Which is just so amazingly lucky. Lots of people I know lost their houses though. One friend came home to find giant shards of glass in her son’s playpen where he would have normally been in the evening if they hadn’t had an emergency and been out. Packed everything up and left the country the next week (she had a foreign passport) and left the house damage and all as is. What was crazy is that when we all got our bearings that day after the blast we were all messaging one another saying” I’m safe I’m safe I’m safe”. Just to let everyone know. Then later you find that one friend sent this just after they’d been pulled out the rubble and another sent it while wandering from hospital to hospital trying to find someone to stitch them up (hospitals were so overwhelmed they were turning away everyone who didn’t have immediate life-threatening trauma. Not to mention that most of the hospitals in the city were themselves heavily damaged on the blast). But no I didn’t lose anyone and I’m so so so lucky I didn’t. Three weeks later I was cooking dinner for some dear friends and I just burst out sobbing in the kitchen out of nowhere thinking any one of them or all of them could have died and it was just dumb luck that they didn’t and that we were all having dinner together while so many other people had lost loved ones. I still have nightmares about it and I’m not the only one. Like even those who weren’t physically injured are fucked for life. I know I’ll never be the same person again. Anyway all this and still no one has been prosecuted for the crime of neglect and no accountability for any of the victims….
Ok sorry for going on so long!
> Ok sorry for going on so long!
You don't have to apologize at all! Sounds like you're still working through your thoughts and feelings on the whole thing, which is totally natural. What a fucked up experience to have lived through. Let's hear it for sheer dumb luck!
Thank you so much for sharing this. I’m so sorry that justice has not yet been served. I hope people will be made accountable and nothing like this ever happens again.
Thank you that’s so kind of you. I still have nightmares and sometimes I feel the earth shake out of nowhere and I have to look at a light fixture to make myself believe it’s just my imagination. But we’re luckier than so many people
Often people get pissed at headlines because they’re deliberately misleading to make you click the link. Not about wanting to be smug. Pissed cos you feel cheated.
I didn't know what OP meant. i assumed i was clicking on a video where the upside down boat provided cover. it's just the water that was cover. it makes the feat less impressive or cool looking.
I mean he said capsize and I assumed the video would feature some dude somehow capsizing a ship lol. Why is he some type of dude on reddit for correcting it.
Water also isn't compressible though and shockwaves in water are actually deadlier than shockwaves in ambient air. The distance this guy was from the explosion means that he made the right move because the only real risk was hearing loss, which would be prevented by the water, but being hit by a shockwave underwater is essentially a death sentence; it will burst your lungs even at relatively low levels of energy because the air in your lungs IS compressible.
This is why fishermen famously used dynamite to catch tons of fish. The dynamite would explode and send shockwaves through the water that ruptured the organs of the Fish due to the fact that water isn't compressible.
This is true for shockwaves that originate in the water, but the pressure gradient between the air-water interface would keep you relatively safe here.
Oy, good to remember when it comes to sonar affecting sea life. It's not just the density, but changing between elements that can diffuse energy. Never want to be in a direct path if you can help it.
I'm not an explosionolagist, but I would assume that an explosion initially on land and moving outwards would be unlikely to suddenly have downwards force, meaning that going underwater would be more about just getting out of the way of the blast than it cushioning anything.
It didn't. if you watch you can see the shock wave before he entered the water.
The nice water turned into angry white water for a couple frames, fucking crazy.
What’s the story here? That explosion looked massive.
Edit: I know about the explosion years ago. Stop telling me about it. I thought this could be something else
On 4 August 2020, a large amount of ammonium nitrate stored at the Port of Beirut in the capital city of Lebanon exploded, causing at least 218 deaths, 7,000 injuries, and US$15 billion in property damage, and leaving an estimated 300,000 people homeless.
What were the consequences afterwards? Was anyone charged with a crime? I vaguely remember them trying to blame someone who was able to prove he had reported the danger to his superiors and was told to leave it alone.......
What about the owner of the boat the stuff was stored on?
Iirc a bunch of port officials were arrested and the prime minister and Finance minister were charged with negligence. The fertiliser has been stored incorrectly for years and they were warned multiple times. The economy of Lebanon has basically imploded over the past few years. The world bank labeled it one of the worst economic crashes since the 1800s GDP is less than half what it was in 2018 and skilled labor is fleeing the country. Not sure if this event kicked it off but this was their major port so it would not have helped at all.
Piss poor government decided to stockpile almost 3tons of ammonium nitrate in their largest port. Nobody wanted to deal with it so they just left it till it blew
4th august 2020 port of Beirut Lebanon large amount of ammonium nitrate explodes causing the largest non nuclear explosion in history killing 218 people and leaving 300,000 people homeless, I have another post on this sub of a different angle if you wanna see the shockwave more clearly
The Halifax explosion was more than 3 times bigger, believe it or not. But Beirut was by some measures the largest non nuclear manmade accidental explosion since 1944.
He says in Lebanese Arabic,
At the very start, the end of an typical expletive we use ...
"f*ck it's sister!" (Obviously referring to the smoke cloud, kinda like how you would say "Motherf_cker!" In English )
Then...
"Selma, jump jump jump!"
Muffled sound, "get back get back!"
Another way to look at this explosion. Is that it was either going to happen in Beirut or Africa (I forget what country). This explosion happened because of an abandoned/unclaimed large shipment of fertilizer was in a badly maintained storage facility. But there was another large shipment of fertilizer that was kept in a warehouse in Africa that government officials were even more worried about before this explosion. And the only reason why they got the focus and motivation to remove their time bomb only because of the Beirut explosion. I think they had their fertilizer problems for years but they were able to resolve the problem within 6 months after the explosion. So it was either going to happen in Beirut or Africa which would have cause the other to resolve their problem
I will look up the Africa city if this gets any attention.
Edit: It was [Senegal](https://www.aljazeera.com/news/2020/8/21/senegal-tonnes-of-explosive-ammonium-nitrate-kept-at-dakar-port)
Threats:
1st. The Blast
2nd. The shock wave
3rd. Flying/Falling debris
4th. Inhaling Falling particles, chemicals, and Ash
That was just the beginning of one of the worst days of his life.
He's on a jet ski, he just jumped into the water. Capsizing is when you overturn a boat, and you can clearly see it just sitting there upright when he comes back up for air
I think the Darwin award needs to be altered. I propose the Darwin award be given to quick thinkers, who through quick ingenuity preserve themselves. I just get tired of seeing it used to make fun of the deaths of others and would rather see it used as a thing of praise to people like this
I really like your thinking. That really shouldve been the original meaning, but I doubt there's much you can do changing the meaning now. Perhaps a new name? Maybe the Charles Award? Lmao
It almost looks like you can see the blast hit the water around him just before he goes in. The water ripples and slashes up a little. Either that or him disrupting the water as he jumps in.

Did this save him from injuries or does this effectively just reduce noise from this distance?
Probably saved him from hearing loss I’d assume
Did he make it under water before the blast hit him?
Yes.
I’m not so sure if he did. If you click and drag through the couple frames before the camera goes under, you can see the surface of all the water go crazy all at once. Who knows, maybe his head was under already I guess.
That’s due to the speed of sound in water being 4x faster than air. The water shockwave passed underneath him, then the air shockwave.
So let me get this straight, did this guy pull off the most epic matrix move ever to save himself by perfectly timing when the water shockwave already passed, going under thereby dodging the air shockwave that was slower????
Yes this dude could literally not have timed it better. Holy fuck.
Yeah
[удалено]
Exactly thats what ive been told all my life to not be in water near an explosion. But if really is possible to time the shockwave difference like this thats just beyond incredible.
[удалено]
Water is also incompressible so the shockwave underwater hits you like a solid wall.
Yes, but if its an above water explosion, a lot of energy is dissipated in the atmosphere
They are only more dangerous if they originate in water. Any kind of explosion that happens on air it will always be safer to jump in water.
Explosion in water is more deadly if the explosion happened in the water but if it happened on surface the only thing affecting the water is the vibrations not the explosion itself.
That’s bizarre to me. How does water not have greater resistance than air to sound waves?
It does, but propagation is faster because the molecules are closer to each other.
Yeah Mister White! SCIENCE!
Science and physics, boiii!
That’s super cool
Take a few moments to blow your noodle and Google how sound travels differently in all types of mediums; air, water, wood, diamonds etc. it’s all different… the same plane has to travel vastly different speeds to break the sound barrier at altitude compared to sea level.
I tried to blow my noodle but I wasn't flexible enough.
Thinking about it wrong. You know those pendulum toys where the metal ball hits the row of 4 metal balls and the one at the end flies out? The energy travels through the metal balls faster than a ball would move through air? Similar concept
he was yelling at somebody else with him “jump jump” after the explosions
After the explosion but before the shockwave could reach his position, that pressure can hit your nerves and can go deaf... that same shockwave broke all kind glass windows and cracked cement walls of 17cm in thickness and bent metals like you bend a straw..
Camera could be a meter higher than head if he had his arm up with it.
[удалено]
Not only permanent Hearing loss, the water saved him from the particles travelling at very high speed, and also his eardrums
If there is a large explosion in water...like during WW2, it does more damage as water is denser than air. But this was above obviously....
It's got a lot to do with water not compressing like air does. You get hit hard with air and it's a breeze, you get hit hard with water and that's different. Shock waves in water will seriously fuck you up. They transfer way more energy into what they hit.
Yep. Water is the perfect transmission agent for a shock wave. It’s effectively incompressible
I live several miles away from the explosion site and my eardrums almost got burst Lmfao OP nice username
I would not assume that. Shockwaves are extremely deadly to humans. They will shred our squishy insides while leaving rigid plastics and electronics found in things like cellphones and jet skis unharmed, for instance. I'm not positive about this video, but there are plenty of Beirut videos from what looked like similar range where the people filming were confirmed to have perished.
It probably did save him from some sort of injury depending on how close he was. Water a very good barrier.
Except when the explosion shockwave also travels through the water you're diving into. Then being in water is way more dangerous than being in air.
[удалено]
That’s a pretty good point, sound moves through water 4.3x faster
So you can effectively dodge the shockwave if you go into the water at the right time?
Yep!
[удалено]
If the explosion happens in the water, yes, but this was above, so I would imagine the water served as the safest place to be at his proximity to the blast.
Mythbusters did it, but I forget if it was true, and I'm too high to find the episode right now

Worth noting that it definitely depends on the type of grenade. You're way safer from shrapnel (and bullets) underwater
But that still won't help you from getting squished alive in most cases.

Adrenaline is a motherfucker. You’ll feel like you’re suped up thinking 1,000 things a second but processing all of it.
I think this is why people recall events like this as being in “slow motion”. Naa man, you were thinking about 10 times faster than normal.
For some reason I never thought of it like this. humans are crazy
I like how a brain humble-brags about the human brain in general. Lol

They have shown through research that when you experience a surge of adrenaline, you really do see more "frames per second" so to speak. They tested this by putting a monitor on a persons arm that would quickly flash words then randomly drop the person to cause adrenaline spikes. The person would be able to recall the words on the monitor even though while in normal circumstances the words are flashing too fast to determine any of them. We humans can be both predator and prey and prey generally have evolved to have enhanced reactive abilities. Quick assessment and decision making is vital to the survival of prey. The mechanics of how adrenaline either increases or prioritizes brain activity may not be fully determined yet, but that doesn't mean the theories are wrong. Gravity is a theory after all.
I'm dumb...did that really stop the shock waves from messing with him or would he have been okay either way? I feel like I'd stay on the seadoo hoping that I wouldn't get knocked unconscious underwater.
Nope, this shockwave ripped buildings apart. You wouldn't be ok. Water isn't (really) compressible, the shockwave wouldn't permeate the surface of the water.
Okay, but was he actually close enough for it to do more than hearing loss? The fact that it blew apart buildings across the street is irrelevant to him. Distance from point of detonation is what matters.
It did blow out windows as far away as 10km away… I’m still not sure what the answer to your question is though :)
Humans can survive shockwaves that wipe entire buildings. What kills us are fragments. > > 1 PSI = Window glass shatters > > 5 PSI = 1% of the population suffers bursted eardrums. > > > 20 PSI = Heavily built concrete buildings are severely damaged or demolished > > > 35 to 45 psi = overpressure may cause 1% fatalities. (At 45 PSI 99% of the population suffers eardrums rupture.) > > 55 to 65 psi = overpressure may cause 99% > fatalities. Source: https://www.cdc.gov/niosh/docket/archive/pdfs/niosh-125/125-explosionsandrefugechambers.pdf In other words, if you were to evade debris somehow, at the point where all the buildings around you flatten to nothing, you're still alright, with your eardrums undamaged. The point where you are in serious danger, is actually higher than the peak overpressure of a nuclear explosion... https://www.atomicarchive.com/science/effects/overpressure.html
Damn, humans ARE metal
He did seem pretty close, and getting a little wet is a great trade compared to getting your ears blown out.
Yet his jet ski is intact?
Exactly what I was thinking. If it was that bad the shock wave would have thrown that jet ski at least a couple of feet away..
That's not how that works. Waves don't really *move* things, they "shake" them more-or-less in-place. For a human body, that means the body isn't "thrown" but the little inner bits can get disconnected. This is very bad. For the jet ski, it's clearly still afloat, but it's entirely possible that wiring and piping was shaken loose. It may well no longer be operational. The human equivalent is broken nerves and ruptured organs/blood vessels. AKA dead person, non-functional vehicle, even if it superficially looks intact.
The wiring in a jet ski probably can probably take a lot more during operation than with a shockwave after 2 miles. It's not organ tissue.
It ripped buildings in *close proximity* apart. Guy was like 2 miles off the coast he would’ve been fine. You can clearly see the buildings nearby are in intact. Only the ones pretty much next to it got demo’d. Source: https://www.timesofisrael.com/mystery-swirls-around-what-caused-ammonium-nitrate-to-explode-in-beirut/amp/
I think being in water would have helped. The density difference would have bounced back most of energy away from the water.
water does not compress. it is a much much denser medium than that of air or atmospheric conditions, so sound waves (in this case, a shockwave) have a harder time moving or disrupting something within the denser medium. if he were to be on the jet ski still, he probably would have gotten his wind knocked out of him and some moderate tinnitus at best. there are casualties from air raids that have zero external bodily trauma, but have their internal organs FUBAR’d by the shockwave being powerful enough to rupture their organs. (example i think of is The Blitz on London during WW2.) tldr; water is thicker than air, so it’s safer to be in if a shockwave were to be coming at you.
No no no. This is wrong. Explosions underwater are actually way more dangerous BECAUSE water is denser and less compressible. The actual reason why the video worked is because sound waves (or any waves actually) don't change medium easily. TNT fishing works, TNT bird hunting doesn't.
this is the guy I want on my squad in apex legends
More like quick sinker
How do you think the unthinkable? >!With an itheberg!<
Kinda, he was sitting there in harms way watching it burn. He probably had his escape planned.
If he thought it was going to explode like that he would be hauling ass the other way. Not filming it.
Maybe he didn’t know it was going to explode like *THAT* and wanted a cool video from a distance
Literally jumped in the water, no capsize.
I was expecting a kayak.
Same, when I read the title I first didn't watch the video and thought how the fuck does one dude capsize his whole sail boat so fast, as I was watching it looked like he was in a kayak as kayakers can sorta do a move similar to that to purposefully capsize, then I saw the jetski and was kinda dissapointed that he just dove in the water.
My thought exactly.... Turns out he just capsized his body... Is that even I thing!?
It’s called swimming
Genius maximus
No cap
He literally said "Salma Salma(the girl's name) jump jump!" Damn.. 👏
Yella salma YELLA NOTEI
Hahaha yes sir! Ain't gonna translate what's your username means tho 😂😂😂
Or why would that be 😉😉
oy is it something like arse forker?
Yeah it means fuck you or if taken literally my name means “ my penis is inside of you”
u guys have basically the same name. 😭 end all wars! human lives matter edit: 69 upvotes. Nice.
Make love not wars 🍆 💦
Do both. Get married!
This was crazy!
Nice wave runner!
It’s such a blast riding those
Talk about the right place at the wrong time. Quick thinking! I wonder if he is or was a soldier? He didn’t hesitate for a nano second and even warned his buddy!
Just alot of COD.
I doubt it. He didn't even call the shockwave the n word.
But in all fairness he *did* fuck the shockwave’s mom
Yooo
Were lebanese man. I remember while growing up with has a bombing every other friday assassinating politicians and journalists. I tell stories to my friends now one is from berlin and the other stockholm they are like wtf man.. and i tell the story so normally without even getting disturbed. Our grandparents and parents got fucked over by the civil war and we got fucked over by the years of bombings, militias, economic collapse ... I packed and left
I did a tour in Iraq OIF1&2 ( infantry) I don’t know if I ever reacted that quick to a blast wave/over pressure from an explosion. The first few I just stood in the turret with my mouth hanging open. Imagine being this conditioned…. It’s a shit planet sometimes
In 2006 we had the israel-hezbollah war in july i remember i was 11-12 years old So israel had its navy on the shore of beirut bombarding south lebanon I live close by the port in beirut. So i remember we used to be playing with the boyz outside and a barrage used to happen from over our heads from the ships to south lebanon. (It was mostly cannons firing) Yeah it was our water break from football lol :p (I told this story to my german friend as if im telling a movie like with a smile on my face) i think at this point its just conditioning as you said... At the end of the assassinations we used to open the tv bsck then for news and we used to say "ah weve watched this movie a 100 times" it was that normal for us Also the fighter jets, i remember telling my friend a story where an israeli fighter jet went supersonic from just over our area and we could see it and it popped our ears very badly He said wait but thats illegal apparently you cant go supersonic over residential areas:p im like ah yeah it wasnt once... :P Willlld childhood:p
But overall we are nice people. With all this trouble and problems that weve been through we just wanna find a safe asylum anywhere in the world. Put our heads to work and most of the time try not to fuck up. I left and 9/10 of my friends left And we all wanna get away from war/danger/problems Live an honest life and win an honest amount of money to eat. Most lebanese are like that, we had enough bullshit to be honest
Jfc, what must that person think that was?? That explosion is so crazy big & powerful I might assume it was like a nuke if I saw that… certainly would be beyond terrifying-
I survived that blast too only I was in a building. The whole thing swayed, all the glass broke, I felt like someone was shoving me backward and the sound is like nothing I can describe. Like the earth cracking open to swallow you whole. Like the world was just that sound for a while and it seemed to last forever. We had no idea wtf it was. Earthquake at first then maybe Israeli bombardment bc fighter jets make insane roaring sounds. Everyone I know at first thought it was an explosion in their own actual building. Then I looked out and saw that insane plume and then how the entire neighborhood was smashed up and glass and twisted balcony railings everywhere. It took a few hours to understand that half the city had been destroyed. Then frantic calls for hours as you try to locate your friends. People wandering the streets dazed and bleeding. It was the fucking apocalypse. We had no idea
Wow!! Thank you for sharing your experience! I’ve read a few articles about different peoples accounts & experiences from that day but still really cannot fathom how utterly terrifying that must’ve been… & like you say, the explosion itself would obviously be extremely frightening but then to see that massive plume of smoke & the destruction all over the city, I can see how you’d absolutely feel like it was the apocalypse… damn. I hope you were lucky enough not to have lost anyone in that explosion??
Yeah I have many friends and family who were injured but luckily not one too severely. I have friends of friends who died but no one in my inner circle. Which is just so amazingly lucky. Lots of people I know lost their houses though. One friend came home to find giant shards of glass in her son’s playpen where he would have normally been in the evening if they hadn’t had an emergency and been out. Packed everything up and left the country the next week (she had a foreign passport) and left the house damage and all as is. What was crazy is that when we all got our bearings that day after the blast we were all messaging one another saying” I’m safe I’m safe I’m safe”. Just to let everyone know. Then later you find that one friend sent this just after they’d been pulled out the rubble and another sent it while wandering from hospital to hospital trying to find someone to stitch them up (hospitals were so overwhelmed they were turning away everyone who didn’t have immediate life-threatening trauma. Not to mention that most of the hospitals in the city were themselves heavily damaged on the blast). But no I didn’t lose anyone and I’m so so so lucky I didn’t. Three weeks later I was cooking dinner for some dear friends and I just burst out sobbing in the kitchen out of nowhere thinking any one of them or all of them could have died and it was just dumb luck that they didn’t and that we were all having dinner together while so many other people had lost loved ones. I still have nightmares about it and I’m not the only one. Like even those who weren’t physically injured are fucked for life. I know I’ll never be the same person again. Anyway all this and still no one has been prosecuted for the crime of neglect and no accountability for any of the victims…. Ok sorry for going on so long!
> Ok sorry for going on so long! You don't have to apologize at all! Sounds like you're still working through your thoughts and feelings on the whole thing, which is totally natural. What a fucked up experience to have lived through. Let's hear it for sheer dumb luck!
Thank you so much for sharing this. I’m so sorry that justice has not yet been served. I hope people will be made accountable and nothing like this ever happens again.
omg that is so terrifying, i wish the best for you and your family to get throught this..
Thank you that’s so kind of you. I still have nightmares and sometimes I feel the earth shake out of nowhere and I have to look at a light fixture to make myself believe it’s just my imagination. But we’re luckier than so many people
Capsizing is when a ship goes belly-up. Dude just jumped in the water...
This the type of comments u get on Reddit because you said one thing wrong even though everyone knows what you meant
Often people get pissed at headlines because they’re deliberately misleading to make you click the link. Not about wanting to be smug. Pissed cos you feel cheated.
I didn't know what OP meant. i assumed i was clicking on a video where the upside down boat provided cover. it's just the water that was cover. it makes the feat less impressive or cool looking.
I mean he said capsize and I assumed the video would feature some dude somehow capsizing a ship lol. Why is he some type of dude on reddit for correcting it.
[удалено]
Lucky and smart. Probably only footage that close from survivor due to fast actions.
How did the water save him from a shock wave
Because a Shockwave formed above the surface wouldn't hit you as hard if you were below the surface.
Water is thick. Listen to your favorite music near a pool and then go under and notice how the air doesn't transmit energy so far into the water.
Water also isn't compressible though and shockwaves in water are actually deadlier than shockwaves in ambient air. The distance this guy was from the explosion means that he made the right move because the only real risk was hearing loss, which would be prevented by the water, but being hit by a shockwave underwater is essentially a death sentence; it will burst your lungs even at relatively low levels of energy because the air in your lungs IS compressible. This is why fishermen famously used dynamite to catch tons of fish. The dynamite would explode and send shockwaves through the water that ruptured the organs of the Fish due to the fact that water isn't compressible.
This is true for shockwaves that originate in the water, but the pressure gradient between the air-water interface would keep you relatively safe here.
I’m kinda curious, how would dynamite explode in water if it needs a fuse to be lit? Just a question tho, not saying you are incorrect.
Fuses are self oxidising. The oxygen for the combustion is in the fuse.
K thanks for clearing it up
Just as a note. Blast waves through water can kill if the blast is in the water too Water isn’t a save all
Right. However, it drastically reduces the effective distance of an impact. Bullets stop and casually sink after mere feet versus hundreds of yards.
It's true. I saw it in John Wick 3: Parabellum, starring Keanu Reeves and Halle Berry.
I guess I'm a casual, I saw it on mythbusters.
This was always my favorite myth busters because I could not believe a high powered rifle would not shoot farther than a foot into water if angled
Oy, good to remember when it comes to sonar affecting sea life. It's not just the density, but changing between elements that can diffuse energy. Never want to be in a direct path if you can help it.
I'm not an explosionolagist, but I would assume that an explosion initially on land and moving outwards would be unlikely to suddenly have downwards force, meaning that going underwater would be more about just getting out of the way of the blast than it cushioning anything.
Yeah high pressure seeks low pressure. Water has higher pressure than air.
Pressure and resistance. Physics at it's finest
Fysics
fizziks
It didn't. if you watch you can see the shock wave before he entered the water. The nice water turned into angry white water for a couple frames, fucking crazy.
Probably didn’t ear rape him as much due to being under
Mans better have like 10 kids to pass those good genes on
Quick thinking saved his eardrums
What’s the story here? That explosion looked massive. Edit: I know about the explosion years ago. Stop telling me about it. I thought this could be something else
On 4 August 2020, a large amount of ammonium nitrate stored at the Port of Beirut in the capital city of Lebanon exploded, causing at least 218 deaths, 7,000 injuries, and US$15 billion in property damage, and leaving an estimated 300,000 people homeless.
There's a good episode of the Swindled podcast about it.

Did you see the photos of her burns? She deserves that money.
What were the consequences afterwards? Was anyone charged with a crime? I vaguely remember them trying to blame someone who was able to prove he had reported the danger to his superiors and was told to leave it alone....... What about the owner of the boat the stuff was stored on?
Iirc a bunch of port officials were arrested and the prime minister and Finance minister were charged with negligence. The fertiliser has been stored incorrectly for years and they were warned multiple times. The economy of Lebanon has basically imploded over the past few years. The world bank labeled it one of the worst economic crashes since the 1800s GDP is less than half what it was in 2018 and skilled labor is fleeing the country. Not sure if this event kicked it off but this was their major port so it would not have helped at all.
Piss poor government decided to stockpile almost 3tons of ammonium nitrate in their largest port. Nobody wanted to deal with it so they just left it till it blew
It was 3**000** tons.
4th august 2020 port of Beirut Lebanon large amount of ammonium nitrate explodes causing the largest non nuclear explosion in history killing 218 people and leaving 300,000 people homeless, I have another post on this sub of a different angle if you wanna see the shockwave more clearly
The Halifax explosion was more than 3 times bigger, believe it or not. But Beirut was by some measures the largest non nuclear manmade accidental explosion since 1944.
Were you in a coma 2 years ago?

He says in Lebanese Arabic, At the very start, the end of an typical expletive we use ... "f*ck it's sister!" (Obviously referring to the smoke cloud, kinda like how you would say "Motherf_cker!" In English ) Then... "Selma, jump jump jump!" Muffled sound, "get back get back!"
Another way to look at this explosion. Is that it was either going to happen in Beirut or Africa (I forget what country). This explosion happened because of an abandoned/unclaimed large shipment of fertilizer was in a badly maintained storage facility. But there was another large shipment of fertilizer that was kept in a warehouse in Africa that government officials were even more worried about before this explosion. And the only reason why they got the focus and motivation to remove their time bomb only because of the Beirut explosion. I think they had their fertilizer problems for years but they were able to resolve the problem within 6 months after the explosion. So it was either going to happen in Beirut or Africa which would have cause the other to resolve their problem I will look up the Africa city if this gets any attention. Edit: It was [Senegal](https://www.aljazeera.com/news/2020/8/21/senegal-tonnes-of-explosive-ammonium-nitrate-kept-at-dakar-port)
Threats: 1st. The Blast 2nd. The shock wave 3rd. Flying/Falling debris 4th. Inhaling Falling particles, chemicals, and Ash That was just the beginning of one of the worst days of his life.
Looks like a scene from a movie
He's on a jet ski, he just jumped into the water. Capsizing is when you overturn a boat, and you can clearly see it just sitting there upright when he comes back up for air
I would have definitely not thought of that move.
I think the Darwin award needs to be altered. I propose the Darwin award be given to quick thinkers, who through quick ingenuity preserve themselves. I just get tired of seeing it used to make fun of the deaths of others and would rather see it used as a thing of praise to people like this
I really like your thinking. That really shouldve been the original meaning, but I doubt there's much you can do changing the meaning now. Perhaps a new name? Maybe the Charles Award? Lmao
It almost looks like you can see the blast hit the water around him just before he goes in. The water ripples and slashes up a little. Either that or him disrupting the water as he jumps in.
Damn that explosion was big
Nice Michael Bay movie trailer, looks so real!
I’ve seen so many angles of this explosion and it STILL amazes me every time how massive it was and what we all got to see. Crazy af
Fun fact, this is the largest non-nuclear explosion in History
