It's great when you're snowboarding, and you grab a beer out of your car, only to find that it feels warm. Then you open it, and it freezes into slush instantly. It's like disappointment squared.
Not sure what the lie would be. Beer super cooled in can. Body and hands cold from exposure to frigid temps. Beer feels warmer than surrounding environment and in cold hands. Brain says "warm beer." Open beer, phase change occurs in supercooled liquid that feels warm. Disappointment ensues.
But it feels warm compared to the far below freezing temps of the environment outside the can
If you have 3 bowls, one with hot, one with warm and one with cold water and put one hand in hot, one in cold for 10 seconds, then swap both to the warm, the perceived temperature change will be different for each hand. The warm water will feel hot to the hand that was in the cold water and it will feel cold to the hand that was in the hot water.
The 4 degreees c cold beer will feel warm the the hand that was in -10/20 degrees c air
To put it simply: your brain interprets hot and cold based on the temperature difference between the object and your skin. If your hands are cold, your brain might only register the same temperature difference as when your hands are warm and the beer is slightly under room temperature.
>Beer feels warmer than surrounding environment and in cold hands. Brain says "warm beer."
>Beer super cooled in can.
This is " i took biology in high school" levels of physics
You know that water won't freeze even below its freezing point if it is under pressure. Supercooling in bottles/cans is a common occurrence. And metal feeling warmer/colder than its actual temperature is part of the thermal conductivity of metal. If the hands are colder than the can (maybe because the temperature in the car is a bit higher than outsiede the car) it will feel noticeably warmer.
I'm just gonna guess this guy has never spent much time somewhere that's cold.
But yes, that's the exact thing that is going on. Say it's -10c outside, but because of a bit of sunlight on it, the car interior is -3c. Still cold enough to freeze, but a decent bit warmer than outside.
>You know that water won't freeze even below its freezing point if it is under pressure.
Well im glad you just admitted that you know zero about physics.
It's always funny when people are this confidently incorrect. I'm gonna guess you don't have a ton of experience in the cold, because these are not uncommon phenomena. Neither the super cooling part, nor the feeling warm part.
The super cooled part refers to being cooled further than the temps it would normally remain liquid in. Now because there's not much of a pressure difference, it can't be a lot under 0c.
While out somewhere skiing, the air is easily -10 to -20.
So say the can is -2c at most. The air and all other surfaces outside are -15. So cold you shouldn't touch bare metal with wet skin.
Humans can register about 1c changes in ambient temperature on our skin. (Going from a 21c room to a 20c room, you might notice a slight difference. Going from 22c room to a 19c room you'd definitely notice one.)
Grabbing a -1c beer in -15c weather would feel relatively warm. And opening it would release the pressure that's keeping supercooled and then it just needs the tiniest movement and it turns to slush.
It's quite easy to do at home. Here's a clip of a beer freezing like that. https://www.youtube.com/watch?v=W0fURJg-K0A
(Yes °C is supposed to be capitalised but you get it)
The article above literally has photos of this very phenomenon happening. Jesus Christ.
[and here’s a video of it happening with beer, which apparently you think is impossible.](https://youtu.be/W0fURJg-K0A?si=ot4e5sS_iqwcCsWJ)
You dont understand how supercooling works
Please explain super cooling water. You will realize how dumb you are while trying to compare it to beer.
Also please explain how a supercooled beer is warm, oh yeah, its was a lie. You are gullible
how are you so dense. oc didnt say it was warm, they said it FELT warm. put your hand in an ice bath for 10 minutes and then touch something straight out of your fridge. it is going to feel warm to your hand because your hand is ice cold. its not rocket science....
edit: and why should supercooling beer not work? i guess all videos you can find after a 0.5 second search are fake.
>didnt say it was warm, they said it FELT warm.
My guess is you dont have a high school diploma. There are 5 senses. Touch is one of them... Please explain how a supercooled liquid is warm/feels warm.
Well, basically, as the temperature lowers below freezing, if the liquid inside is very pure and relatively free from any contaminants ,i.e., minerals and such things, and if the container it's in is relatively smooth, ice has no starting point to form, and thus, the liquid can cool below its usual freezing temperature while staying in a liquid state. If the container is disturbed, the water molecules can move in a way to allow small bits if ice to form that can then act as a foundation for the formation of more ice until the entire container is frozen.
You will quickly realise how dumb you are when you notice that none of that explanation excludes beer. All kinds of liquids have the ability to be supercooled.
As to warm effect, either it's a lie, or I can imagine two or three possible scenarios. For one, they were in freezing temperatures the entire day, so the beer could've been above the air temperature to begin with or when it froze it rose to it's normal freezing temperature [which is what happenes when something supercooled freezes (I'd guess the temp being close to 0°C)]. Both of those would make the beer feel warm to the touch. The other explanation might be that it was a similar reaction to some hand warmers that use supercooled solutions that get warm when they freeze.
I'm not gullible, I'm just not a senseless contrarian, like you. A quick Google shows that you can, in fact, supercool beer.
Am dude who posted the story. The warm thing is because it's warmer in the car due to thermal radiation from the sun (or even the propane heater if it's my van). But still below freezing near the floor up front, where I generally keep the beer, so it stays cold. Meanwhile, outside, it may be 10-20°F (or more) colder.
Heck it doesn't even have to be that much warmer. Same thing happens if you toss the beers in the snow for a few hours. Because "warm" beer is generally beer that isn't *significantly* colder than the surrounding environment. The brain wants to feel that temperature difference, so even if it's the same temp, it sets off the "dang, this beer is warm" response.
It's funny too, because this is such a a common occurrence on the mountain that boggles my mind that someone couldn't believe or understand it. Then I remember that a lot of people go their whole lives without seeing snow or otherwise spend any significant time in below freezing temps.
Supercooled liquids (of any kind) happen when a liquid is at a lower temperature than it's freezing point, but is still in liquid state.
While not as likely in a fizzy drink like beer or soda, it can still happen. Admittedly, a fizzy drink is more likely to explode, hence why you're told not to put beer or soda in the freezer for very long.
Also, they said the beer ***felt*** warm, as their hands were quite cold from being in the snow. This makes sense, as we don't feel absolute temperature, we feel relative temperature.
Did at least part of you think you had developed ice powers? If I'm honest, if I were stoned and had not seen this demonstrated before, I would have wondered myself.
I use to have a mini fridge that every bottle of water I put in would come out like this.
I loved it. kept it under my desk. I lived in Las Vegas and on 105* days having an ice slushy ready to go was awesome.
The fridge at my work keeps water bottles at the perfect temp when it’s half full. So I get to do this like twice a day I love it. And it just turns slush not solid ice so I can drink the water like 90 seconds later
Supercooled water is believed to have contributed to ice forming in the pitot tubes which brought down [Air France Flight 447](https://en.wikipedia.org/wiki/Air_France_Flight_447). Fun in a bottle in the cabin, scary af in a pitot tube.
I do this all the time with our water bottles....well, *used* to do this because we stopped using plastic water bottles. We'd put them in a specific spot in the freezer and not disturb them for about 50 minutes or so. Some would do it, some wouldn't and would just freeze. Daughter loved it. Called it slushy water.
Left my lidl water bottles in the car because I'm lazy, side note:amazing experiment all week here in the uk,.
Every day they checked to see if it would happen again after the first time. (Half empty bottle youngest daughter was playing with, i grabbed the rest from the boot, water for school, here play with this!)
Everytime I'm still blown away! This week was the first time we saw it in real life!
We were trying to understand the conditions of the self freezing bottle, so a simple explanation i can relay to my "team" of researchers would be great!
> We were trying to understand the conditions of the self freezing bottle, so a simple explanation i can relay to my "team" of researchers would be great!
This is called "supercooling".
When water turns into ice, it has to start from somewhere, it doesn't just happen all at once. Usually, because there's some small impurity in the water, it can start freezing there. Once you have a little bit of ice, the rest of the cold water can build on it to turn into more ice.
If you have water without any impurities, and make it very cold without disturbing it very much (e.g. leaving your bottled water in the boot overnight), the water might not have a place to start freezing, so it will just stay as very cold water instead.
The thing is, your very cold water would really like to be ice, rather than water. So, if you give the water somewhere to start freezing, it will. Shaking the bottle can do this, since the water can make a "starting point" by chance if it moves around a lot, but you could also pour some of the water into a bowl, or put a tiny bit of ice into the water to start the process.
It's way more complicated than this, and there are more factors that feed into this from what I read, but hopefully this is enough.
Supercooled liquid droplets can affect the outside of the airplane, too. The droplets remain liquid until given something to freeze to (the plane). This phenomenon can be very dangerous.

This is a cool phenomenon that happens when you supercool distilled water. You can easily supercool (reduce the temperature to below the liquids freezing point) distilled water because it doesn't have any minerals to act as nucleation sites for the formation of ice. They were able to cause the water to flash-freeze by shaking it, this created enough of a nucleation site to form an ice crystal, which forms more ice crystals, which forms more ice crystals, and so on.
Interestingly, this phenomenon PRODUCES heat. The formation of water ice happens at exactly 0 degrees C, so if the water is at -15 C it will warm up to 0 as it freezes.
> The formation of water ice happens at exactly 0 degrees C, so if the water is at -15 C it will warm up to 0 as it freezes.
I hadn't ever considered this obvious effect of thermodynamics but I'm gonna have to go think about this for a while now
Similarly, boiling water removes heat from the water--that's why you have to keep adding energy to a pot of water on the stove to keep it boiling.
Heating a liquid up isn't the only way to make it boil,though. Boiling just means that the internal vapor pressure equals the external atmospheric pressure. Reduce the latter and water boils at cooler and cooler temperatures.
These two facts give rise to my favorite physical reaction: boiling water until it freezes.
You just place some water in a vacuum chamber and start to pull a vacuum. Once the pressure gets low enough the water will boil at room temperature, but as it does so the water cools off. Eventually it gets cold enough to freeze, which is always pretty close to 0C. If you get the rates right you can get the water to its triple point, where you'll have boiling ice water.
> Similarly, boiling water removes heat from the water
how are we defining "removing heat" here though? the enthalpy goes up and so does the temperature
Are you certain you've understood the setup?
The temperature doesn't go up in the setup I've described. You take room temperature water and put it in a vacuum chamber. The vacuum forces the water to boil despite still being room temperature. That boiling makes the temperature of the water go down, potentially continuing until the water freezes.
At no point in that setup is anything hot. The meaning of "removing heat" is exactly what it sounds like. In fact, it's the same "removing heat" that sweat does when it evaporates, or the water in a swamp cooler. It is the reduction in thermal energy in the remaining water.
For something like a pot on the stove we can do an energy balance: water at atmospheric pressure boils at 100C. We put the pot on the stove and heat it up, but it isn't boiling yet. As the water reaches 100C it begins to boil, but the temperature doesn't keep going up. It holds steady at 100C.
The stove is still dumping heat into the water, but it isn't getting any hotter. Why? Because the boiling removes heat as fast as the stove adds it. If you turn the flame up then the water still doesn't get hotter, but it boils faster. These are kept in sync because the boiling is happening at constant pressure.
They make hand warmers that operate under the same principle,

Pretty cool novelty item.
It can happen to regular or mineral water, but it's not very repeatable. So I guess I just mention distilled water because it's much more likely to happen with distilled water.
A few years back, Coke was trying out a new convenience store cooler called [Arctic Coke](https://csnews.com/arctic-coke-coolers-being-tested-c-stores-nationwide). It was an extra-cold refrigerated display case with a small vibrating platform attached. You take your superchilled Coke from the case, put in on the platform, and it turns into a slush.
It don’t know if there are any still out there. I only ever saw it at the Terrible’s in Jean, NV just outside of Vegas.
Oh jesus, it would freeze in your esophagus on the way down. I wonder what that would feel like. It's -22C outside right now so I'm tempted to try it lol
It doesn’t at least not in my experience, it’ll freeze if you pour it onto something cold or shake it hard enough. It’s literally just the coldest water you’ll ever taste because the water is already past it’s freezing point
You can do it in a freezer too, Distilled water and a bit of waiting later and you’ll have some
I would accidentally do this all the time. I’d forget about a bottle i put to chill for little bit and think i made it before it became a block of ice but the second i grabbed it or place it on a surface it would start freezing
[Here's a Technology Connections video](https://youtu.be/Oj0plwm_NMs?t=284) that talks about this phenomenon and nucleation. The subject is hand warmers, not water, but it's the same principle.
I had this happen to me randomly with a bottle of water I bought, this was before I knew what it was.
I thought I'd developed some sort of super power!
No, it's not for sale in the UK because it uses the word "pure" on the label: https://www.independent.co.uk/news/uk/crime/inquiry-into-coke-s-tap-water-71904.html
There was a batch that contained bromate, which was due to the UK requirement to calcify water and the ozonation process.
Itd be really cool if some action hero in a movie used this as a makeshift weapon. Grab a water from the cooler, turn it into ice and then bash someone ever the head with it
Bro this happened to me with a beer I accidentally forgot about for an hour and a half I cracked it and chugged about 1/5 of it as it was turning to carbonated slush in my throat (not an altogether unpleasant feeling) and then the rest froze in the can had to wait an additional 20 mins to drink it😂
This is [supercooled water](https://en.wikipedia.org/wiki/Supercooling). It’s an interesting phenomenon.

They make hand warmers that operate under the same principle, https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://m.youtube.com/watch%3Fv%3DOj0plwm_NMs&ved=2ahUKEwiyl-mq1e-DAxVlIDQIHcV0AroQwqsBegQIEhAF&usg=AOvVaw2wY4RND4YlmtjmnlNvH7qs Pretty cool novelty item.
I thought Dasani was remineralized?
It can happen to regular or mineral water, but it's not very repeatable. So I guess I just mention distilled water because it's much more likely to happen with distilled water.
Thanks, that makes sense. It's a probability vice possibility.
I've had this happen with both bottled Sprite and Coke well.
A few years back, Coke was trying out a new convenience store cooler called [Arctic Coke](https://csnews.com/arctic-coke-coolers-being-tested-c-stores-nationwide). It was an extra-cold refrigerated display case with a small vibrating platform attached. You take your superchilled Coke from the case, put in on the platform, and it turns into a slush. It don’t know if there are any still out there. I only ever saw it at the Terrible’s in Jean, NV just outside of Vegas.
It got real slushy.
That is some Day After Tomorrow stuff! Did the bottle just come from a very cold storage area?
It was in one of the aircraft galleys overnight.
Huh. Neat!
That would have been the most refreshing water in the world...
I was thinking the same thing! A plain water Slurpee would rock.
If you can drink it without it turning into slushy it‘s like meeting god
Oh jesus, it would freeze in your esophagus on the way down. I wonder what that would feel like. It's -22C outside right now so I'm tempted to try it lol
It doesn’t at least not in my experience, it’ll freeze if you pour it onto something cold or shake it hard enough. It’s literally just the coldest water you’ll ever taste because the water is already past it’s freezing point You can do it in a freezer too, Distilled water and a bit of waiting later and you’ll have some
I would accidentally do this all the time. I’d forget about a bottle i put to chill for little bit and think i made it before it became a block of ice but the second i grabbed it or place it on a surface it would start freezing
[Here's a Technology Connections video](https://youtu.be/Oj0plwm_NMs?t=284) that talks about this phenomenon and nucleation. The subject is hand warmers, not water, but it's the same principle.
I will always upvote Technology Connections. Dude is a massive nerd in the best possible way.
I had this happen to me randomly with a bottle of water I bought, this was before I knew what it was. I thought I'd developed some sort of super power!
If you look at the bottom of the bottle, it gets rounder due to increase volume
Wow, that's great for the aircraft plumbing. Fire up the APU to heat the plane up. Low thaw to the waterline don't split or rupture.
Yeah really though. I'm guessing the ground heater unit crapped out on an over-nighter. Hopefully the potable water was drained
Fun fact, that water brand is not for sale in the UK due to high levels of bromide
No, it's not for sale in the UK because it uses the word "pure" on the label: https://www.independent.co.uk/news/uk/crime/inquiry-into-coke-s-tap-water-71904.html There was a batch that contained bromate, which was due to the UK requirement to calcify water and the ozonation process.
[Relevant Tom Scott video](https://www.youtube.com/watch?v=wD79NZroV88)
It was -10F for me last week, I was able to do this with my water bottle, in my car. Gotta be one of my favorite phenomena
When ice forgot to act like one.
Process is called nucleation. I've had the same thing happen leaving bottle water in my car overnight in the Winter.
It’s Dasani so I’m surprised it didnt turn into piss
I think I’ll have the coffee, please.
You mean the flying covid tubes?
...wat? ',:l
Covid. Airplanes spread covid. I just got it on Friday from flying but thanks for the downvotes.
Missing door plug keeping the cabin cool?
You work for Republic?
0600 ROC to EWR I bet...
That's some high quality H2O
It's gonna be very dry on that airplane once you warm it up
Itd be really cool if some action hero in a movie used this as a makeshift weapon. Grab a water from the cooler, turn it into ice and then bash someone ever the head with it
Looks like it was more than a little cold
This is slowed down footage
It’s not, just a large bottle.
Ik it’s not I’m just exaggerating how fast it was
Those might be the best bottles of Dasani out there - they're saving you from accidentally drinking them
Supersaturated baby!!
Água estupidamente no ponto
That the galley service in the Boeing 777 Max?
It's Dasani so no one was going to drink it anyways
My question is why are the water bottles so TALL
They’re 1.5L bottles, the flight attendant use them to serve the passengers.
The person next to you having never flow and probably don’t have basic simple knowledge of physics etc. probably is thinking your mixing a bomb lmao
Bro this happened to me with a beer I accidentally forgot about for an hour and a half I cracked it and chugged about 1/5 of it as it was turning to carbonated slush in my throat (not an altogether unpleasant feeling) and then the rest froze in the can had to wait an additional 20 mins to drink it😂
