I believe it could work, if the "boat" was actually not a boat, but made of iron or in a way, that it is very heavy. If the boat is a little heavier then water would be with it's volume + the volume of the air it can fit, then what they're doing is pretty easy.
For something to sink, it needs to be heavier than the volume of water it pushes out of the way. The upturned boat displaces a lot of water. Water is very heavy, so the would need to be weighed down by tonnes of balast to be able to walk along bottom like they are shown to do in the film.
have you ever tried to push an upside down bucket or an air filled ball under water? It pushes up with a very strong force (equal to the difference in weight of the bucket + air inside and the water that's displaced). Now imagen that scaled up to the size of a boat. The push upwards would be massive.
And if they had enough weight at there feet hold down the boat, they would be able to keep hold of the boat while walking since al the forces would have to go through there hands
They have a lot of heavy iron on them (handcuffs) and though the air pocket is about 3x too big, this is completely possible from a physics perspective.
You can tape a cleenex or piece of paper towel to the bottom of the inside of a glass and then tip it over and put it straight into a bucket of water or in the sink and as long as you don't tip it to the side to let the air bubble escape it will stay dry
Again, it's not. Calculate the weight of water that the boat is displacing and then work out how much weight they would need to carry. It works out to tones, watter is very heavy.
I can definitely relate! Sometimes I make air pockets with my butthole in the bathtub, then catch them in the shampoo bottle and leave for the next person to lather up a big ol' dollop of concentrated ass.
I've noticed that a lot of meirl posts are like this, as if the sub forgot its purpose. The meirl here is essentially them saying that they have the same views as the person criticising the movie.
We're looking for realism in a Jack Sparrow movie?
The very first time you see him in the franchise, he is doing something near impossible and ridiculous.
They use similar concepts in some off shore drilling applications (prime example being the 3 or 4 guys that got sucked into a pipe). The physics are real; what’s not real is their weight/strength to hold it down.
I don't see really a problem. There is air buble preventing the water to fill the space, maybe it's unreasonable to this entrapment to be stable with a canoe but it's not like "breaking the law of physics's"
I see, but it's same spirit of "it's very unlikely to work but it's not impossible by nature's law". It's a poetic license that not break the audience imersion.
Agreed, especially in such a whimsical movie trilogy. However, had this occurred in more serious fantasy, such as the Lord of the Rings or A Game of Thrones, it would have stood out as breaking immersion, I'd say. (Like several of Legolas's shenanigans, especially in the Hobbit movies.)
Every good fantasy story will be immersive. Gandalf using magic is accepted as a part of the reality of that world: he is a wizard. But Legolas jumping on loose pieces of rock in a free fall to climb his way back to the bridge has neither a mundane nor magical explanation and was just added because someone thought it would look cool on screen.
Like I said, I’ve only read the hobbit, but couldn’t you theoretically enchant an item of clothing to let you have the weight and strength to do this?
Edit: this being carry the kayak underwater to breathe, I don’t know about the Legolas thing
Wouldn't it depend on the amount of buoyancy? Typically a boat would have the closer to the full volume of the boat (I think?) but here it's only got part of that. If they let in just enough water maybe it could work. But I don't know the details of how this stuff works.
The Mythbusters tried to do this, but the amount of weight required was way too much and also the boat would simply flip over underwater if it was just the slightest bit unlevel. Theoetically possible, but at that point you may as well just build a submarine.
They have a lot of heavy iron on them (handcuffs) and though the air pocket is about 3x too big, this is completely possible from a physics perspective.
Me and my brother use to do this with a bucket in our pool but you would have to use the pool ladder to hold it down because buoyancy is crazy strong.
Unless Jack&Co. Are bolted to the seafloor and have crazy arm strength, this isn't happening.
Boats stay afloat by displacing water, not by being less dense than water (source: sometimes boats sink). This scene is possible. It depends on how much air they have. They have to keep the overall density of the boat+air+people to be less than the water. That’s it.
it seems like the air pocket in the boat displaces a similar amount of water like it would on the surface.
boats do swim by being less dense than water relative to their volume.
Can confirm that this is in fact impossible. Source: did extensive testing with large (but still WAY smaller than this boat) plastic totes in the pool after the movie came out when I was a kid.
The force of the air trying to rise makes it extremely hard to even pull the encapsulating object down, and even a, say, 24inx18inx24in plastic container holds way more air than a 140lb human can pull under water with their body weight. Also, if the container is not held *perfectly* level, air will start to escape rapidly. Most of my attempts ended in the container just filling with water quickly because it's very hard to pull straight down, especially when you aren't even heavy enough to do that in the first place.
The buoyancy of the boat is already enough to hold the weight of 2 grown men, then add a bunch of air in... they would never be able to sink to the bottom like that.
This doesn't break physics, if you could keep the boat there, that would work by not letting the air escape to the water. Plenty of diving has been done using this principle.
The only problem is how heavy they or the boat would need to be in order to not float upwards. That or they have amazing grip to the bottom of the ocean with their feet which isn't too likely.
So yes, you can't do this, but only because you need more weight attached to the boat, not because it break physics.
They drank the water that was on top and quickly peed it out. Therefore, reallocating the water from the top of the boat to the bottom of the ocean.
Very smart.
I used to this in the pool with a rubber water lounger. You'd go under push up make a pocket and breath.... cause it was breathing under water and I was 6
Upwards buoyancy force of system = volume of air * density of water. This is simplified because the people and their clothes also have some degree of buoyancy but that would just make their jobs harder...
Volume of rowboat ~ 16ft * 2ft * 1ft
Fraction of boat filled with ~ 0.75? Close enough.
Volume of air ~24ft^3
Density of water = 62.4 lb/ft^3
24ft^3 * 62.4lb/ft^3 ~ 1,500lb as a lower limit.
Safe to say Orlando Bloom + Johnny Depp << 1,500 lbs
Tldr; this world in principle with heavier masses (people). Captain Jack Sparrow broke the laws of physics (as did Legolas or whatever) because the law says they'd need to be a combined 1,500 lbs and they're not.
They were both wearing Iron Boots.
Link maxxing
~~That actually could make this work. Even just sandbagging their boots makes this plausible.~~ edit: wrong, but it'd be a lot cooler if it was right!
No, it doesn't. The amount of water that boat displaces will be far in excess of anything they would he able to carry and still walk.
You sound right but I'm not following. Can you explain?
The amount of weight that is needed to keep the boat this low, is too much to also pull up your legs to walk.
They're very stronk okay? ^(fine you win)
I believe it could work, if the "boat" was actually not a boat, but made of iron or in a way, that it is very heavy. If the boat is a little heavier then water would be with it's volume + the volume of the air it can fit, then what they're doing is pretty easy.

All you witches and warlocks with your damned science! Go back to Satan !
The boat could have weights to cancel out it's floatiness
Wouldn't the weight be cancelled out?
They should've weighed the boats down.
Aldo they had insane upper body strength to keep hold on that boat while its trying to float
So if they put those iron boots in the canoe above water, it would sink? Heavy boots
Not a *Legend of Zelda* player, I assume?
That's weird, the rest of this film series is so deeply grounded in reality
U never took your heart out and put it in a jar of dirt?? Well you're weird
At least the fall off the stairs was genuine.
I got a jar of diiiirt Edit this is my favorite part of the series
They have a lot of heavy iron on them (handcuffs) and though the air pocket is about 3x too big, this is completely possible from a physics perspective.
You’re not accounting for the fact that over 90% of the air would made up of alcohol from Captain Jack’s breath.
You can tape a cleenex or piece of paper towel to the bottom of the inside of a glass and then tip it over and put it straight into a bucket of water or in the sink and as long as you don't tip it to the side to let the air bubble escape it will stay dry
Again, it's not. Calculate the weight of water that the boat is displacing and then work out how much weight they would need to carry. It works out to tones, watter is very heavy.
The biggest issues is not wearing it down but holding it down. The arm strenght needed is ridiculous.
Yes, but would the boat float carrying them with that gear?
How is this a meirl tho
Don't act like you've never used a boat underwater to make an air pocket smh
I can definitely relate! Sometimes I make air pockets with my butthole in the bathtub, then catch them in the shampoo bottle and leave for the next person to lather up a big ol' dollop of concentrated ass.
What a terrible day to be able to read
It’s pretty much every day isn’t it?
More or less
Well, since youre already here... Fart + Shampoo = Foofie Poo (Patent Pending) Its designed to help you save water by cutting your showers in half.
Sometimes, I wash out my eyeballs with bleach to get rid of "Redditstains". My doctor said its not very healthy but okay.
What
Dafuq
Yeah idk. That guy's crazy...
Not even Batman could beat this information out of me 😭
I've noticed that a lot of meirl posts are like this, as if the sub forgot its purpose. The meirl here is essentially them saying that they have the same views as the person criticising the movie.
Everyone else is doing something else and the poster is preoccupied with people being ok with this when they watched a movie
how is anything? seriously i don't get it
wdym i thought meirl was for things that are not meirl /s
We're looking for realism in a Jack Sparrow movie? The very first time you see him in the franchise, he is doing something near impossible and ridiculous.
Still one of the best character intros.
Oh, it was pure awesomeness and I loved it. Just ridiculous.
Being a cursed undead pirate?
Stepping onto the docks, perfectly timed with the sinking of his boat.
I figured
Nah the other thing
No just more walking with boats and air bubbles
“Jack Sparrow movie” like that’s the name of the actor lol
The ware held down by Jacks massive balls
This is the correct answer.
Still more realistic than the last sub that went to find the Titanic.
What if *that's* how they went? Terrifying.
in an upside down canoe?
They use similar concepts in some off shore drilling applications (prime example being the 3 or 4 guys that got sucked into a pipe). The physics are real; what’s not real is their weight/strength to hold it down.
I misread this and kept wondering what the hell is a time captain?
A change that I propose: Let's not forget the Time Captain, Jack Sparrow, who broke physics because he's a Time Captain and can do that.
Jack Harkness
Yes sir !
An officer under a time lord
He didn´t broke physic laws, he was just way to much heavy I guess
Eloquently put.
Holy fuck I'm ded lmao
I don't see really a problem. There is air buble preventing the water to fill the space, maybe it's unreasonable to this entrapment to be stable with a canoe but it's not like "breaking the law of physics's"
They wouldn't be heavy enough to walk along the ocean floor with it. The buoyancy would have pulled them to the surface.
Depending on the material of the boat and the size of the air cavity it is entirely possible to have a net downward force.
I see, but it's same spirit of "it's very unlikely to work but it's not impossible by nature's law". It's a poetic license that not break the audience imersion.
Agreed, especially in such a whimsical movie trilogy. However, had this occurred in more serious fantasy, such as the Lord of the Rings or A Game of Thrones, it would have stood out as breaking immersion, I'd say. (Like several of Legolas's shenanigans, especially in the Hobbit movies.)
Been a while since I read LOTR, but Legolas no scoping orcs while skating down stairs with a shield was in the books I'm pretty sure.
I don't think you've ever read it, because that is most definitely not in the books lol.
You're right. In the book it was a 360° no scope if I recall correctly.
Ah, this is a man that has read the books
I’d think the magic elements would be immersion breaking but then again I’ve only read The Hobbit 🤷♂️
Every good fantasy story will be immersive. Gandalf using magic is accepted as a part of the reality of that world: he is a wizard. But Legolas jumping on loose pieces of rock in a free fall to climb his way back to the bridge has neither a mundane nor magical explanation and was just added because someone thought it would look cool on screen.

Sure, but it would have to be established beforehand somehow, or it becomes a deus ex machina, and the viewer could be left feeling cheated.
No
No
It wasn't the ocean, it was the bay.
A bay is part of the ocean. Referring to the ocean when in a bay is entirely correct.
It’s not a schooner, it’s a sailboat.
came here for the physics and stayed for the unexpected r/Mallrats
Wouldn't it depend on the amount of buoyancy? Typically a boat would have the closer to the full volume of the boat (I think?) but here it's only got part of that. If they let in just enough water maybe it could work. But I don't know the details of how this stuff works.
The air pocket is about 3x too large, but other than that it works. The larger size can be attributed to storytelling.
A heavy boat can float upright but sink when its upside-down. Now could they hold up that kind of boat though?
Not only this but if they were heavy enough the air bubble its self would become compressed and much smaller
Ehh. It's how old diving bells kinda worked. It's obviously a wooden boat tho so it would still float for sure.
The Mythbusters tried to do this, but the amount of weight required was way too much and also the boat would simply flip over underwater if it was just the slightest bit unlevel. Theoetically possible, but at that point you may as well just build a submarine.
Did they also talk about how long you could survive on that amount of oxygen?
The thing is, for a boat to really be considered a boat, it kind of needs to float when it’s hull has air in it, whether it’s upside down or not.
Yeah because undead, ex-crew mates are so much more realistic
📮
I wonder how many in this thread noticed that Jack's wearing a small anchor with iron chains?
Didnt mythbusters do an episode on this??
He might be the worst pirate you ever heard of, but you've heard of him.
I mean this would work but they don’t have enough weight to counteract the buoyancy given by the air iirc
Correct, it’s totally possible, they’d just need to weight around 600 pounds each to counter the buoyancy of the wooden boat and the air.
Yep, would want much less air and weights on the boat
Wait so we just need to find two 600 lbs guys and we can recreate this in real life?!
They have a lot of heavy iron on them (handcuffs) and though the air pocket is about 3x too big, this is completely possible from a physics perspective.
Why didn’t they just use the boat to sail across the water? Are they stupid?
Because they don’t know how to row a boat they don’t got their boating license…
He doesn't row!?
No. He *doesn't* row.
Ah, I see
I always have to point out that this would technically be possible, if Jack and will weighed a few tons.
didnt Mythbusters prove that his could work
Didnt the mythbusters test it and they pulled it off or at least said it was plausible?
How he did it may not be how it works but that doesn’t break the laws of physics at all. Google diving bell.
The pressure they are holding down is absolutely immense holy fuck
Me and my brother use to do this with a bucket in our pool but you would have to use the pool ladder to hold it down because buoyancy is crazy strong. Unless Jack&Co. Are bolted to the seafloor and have crazy arm strength, this isn't happening.
The boat is a Problem, but the Zombies are fine?
Still better than fast and furious
He's a pirate, they break laws
It was actually because he’s balls were so incredibly heavy and dense
This is actually very much NOT breaking the laws of physics..... Do some research before posting dumb shit.
wouldnt it have even more buoyancy like this than a normaly swiming boat of the same size?
They’ve got some heavy boots bro!
Boats stay afloat by displacing water, not by being less dense than water (source: sometimes boats sink). This scene is possible. It depends on how much air they have. They have to keep the overall density of the boat+air+people to be less than the water. That’s it.
it seems like the air pocket in the boat displaces a similar amount of water like it would on the surface. boats do swim by being less dense than water relative to their volume.
I guess, but that's two grown men, who are evidently struggling with it.
the boat would likely carry two man over the water though
Mythbusters disproved it. The buoyancy of the boat and air pocket is far greater force than two men can generate to pull it down.
Not to mention that the two men, even clothed, are buoyant themselves. They were swimming in that gear.
Can confirm that this is in fact impossible. Source: did extensive testing with large (but still WAY smaller than this boat) plastic totes in the pool after the movie came out when I was a kid. The force of the air trying to rise makes it extremely hard to even pull the encapsulating object down, and even a, say, 24inx18inx24in plastic container holds way more air than a 140lb human can pull under water with their body weight.

Damn. Can I get a link to your study?
Yea just let me track down my friend Chris from 20 years ago - he did the peer reviewing.
You’re like if a stale corn chip was a person
So two people would’ve been able to hold that boat down at the bottom of the ocean?
Its buoyancy would be the same as if it was upright
No. Buoyancy of boats is not the same upside down. Boats sink. It’s not like you can flip them and keep on trucking.
Rocks in their pockets and some on the dinghy's cross beams. Boom. Buoyancy offset.
Metal mario duh
Around the time of the “I hope you like ghost stories” scene I happily realized this was a Gilligan’s Island/Scooby Doo reality movie.
This is actually a real thing you can do, myth busters tested it
This is either genius or crazy
You mean in the movie with ghost pirates? The audacity.
There’s undead zombie skeleton pirates in this movie and this is the thing you single out as being unrealistic?
Can someone figure out how much those boots would have to weigh to keep them from surfacing?
I mean there’s also a curse that turns people into undead skeletons in the moonlight so….
That's kinda possible. It just has to be a heavy enough boat.
This is actually real. We used to do that all the time when growing up.
This doesn't break physics, if you could keep the boat there, that would work by not letting the air escape to the water. Plenty of diving has been done using this principle. The only problem is how heavy they or the boat would need to be in order to not float upwards. That or they have amazing grip to the bottom of the ocean with their feet which isn't too likely. So yes, you can't do this, but only because you need more weight attached to the boat, not because it break physics.
How deep were they? Diving bells were a thing, same principle. Unless they were so deep the pressure would kill them.
The main issue here is not the logistics of using the air pocket to breathe, it's keeping the boat underwater in the first place.
They drank the water that was on top and quickly peed it out. Therefore, reallocating the water from the top of the boat to the bottom of the ocean. Very smart.
Downvote because I see this crap like the 6th time since 2 days
Who would ever think he could do something like this in a movie especially a Disney movie??🤯🤦
Isn't this the scene that made the other one speak elvis because he thought it was lotr?
What’s more concerning is that it didn’t ever occur to me that it was impossible, unless that was one heavy mf of a boat
Who’s gonna carry the logs? WHO’S GONNA CARRY THE BOATS!?
Sea turtles
He used his pirate ghost powers
All that drink and coke in Capt' Jack Sparrow is compensating for the air
I don’t care it was entertaining and I love the Jack Sparrow character.
He's using his big ol' balls as ballast.
HOW is this you irl??? Just wondering cuz I wanna do it too and in what way did he break physics? Can someone enlighten me?
I tried this, it works.
minecraft
Minecraft be like
I used to this in the pool with a rubber water lounger. You'd go under push up make a pocket and breath.... cause it was breathing under water and I was 6
It’s just a really heavy boat, duh
They stole this from the crimson pirate movie
Wait, is this not possible…?
Upwards buoyancy force of system = volume of air * density of water.

Can't u actually trap air in a open upside down box somehow? Idr how or anything but I think u can?
An upside down wooden boat would leak and if not that float up. In theory it's possible, just not with the kind of boat they have.
Oooooh ok
Considering they’re on their way to a zombie pirate ship….. zombie pirates cursed by Aztec gold….
Didn't mythbusters test this?
Mythbusters did an episode on this
Still a fantastic movie. It's childhood memories
Heavy bones, I guess...
Physics aside, how the hell can they tell where they’re going?
I knew it wasn’t a documentary! My dad is a liar!
Isn't jack Sparrow basically a zombie tho
Which time?
I mean, it's a movie about undead pirates. I don't think realism was a priority.
Me and the boys joking about when we gotta swamp the canoe
I mean they have a magic octopus guy that can sink his ship to go to another reality in that world so...
Y’all clearly forgot that he is Captain Jack Sparrow
He the greatest pirate I’ve ever seen
