I'm the guy who shot the video. This was our SECOND experiment with LN2 in the pool. The first batch went in the hot-tub, and we lamented not having filmed it. The cloud of vapor was amazing. If you attend Penguicon, and they're having Liquid Nitrogen Ice-Cream ("instant" ice-cream) on the same floor as the hotel pool, there's a good chance of a repeat performance. It's much more impressive in real-life than on RUclips.
One of the cool things I can say about this video as I was actually there as a little kid and is a 33-year-old adult I will say that is one of the coolest memories I’ve ever had as a kid thank you 🙏
@knaxon In a swimming pool the amount of chlorine is quite low and therefor not really toxic - think of it: Even salt has chlorine, your stomache acid is a liquid also containing chlorine ions. And so on.... And throwing nitrogen in this pool causes nothing but an intersting picture to look at. Around 78 percent of the air you breeth contains nitrogen. The nitrogen even won't get dissolved in the water.
You would need about 55 gallons of liquid nitrogen to change the temperature of the pool by only 1 degree (C). You would need about 1500 gallons to freeze the pool. The amount they added would have no noticeable effect on the temperature of the water.
This is a terrible idea. If youre close enough you can suffocate easily. The reaction with water causes the oxygen to be displaced so rapidly. And most people dont even know they are suffocating because it wont feel the same as any other lack of oxygen they can, or would, experience in their normal lives
TheMedicalOfficer It's not the nitrogen that we breath, its the 21% oxygen. When the nitrogen displaces the oxygen in the air further you can suffocate.
+Jackie Gonzalez that's exactly what it is:-) clouds are just condensed water vapor created by changes in temperature and air pressure - that's exactly what the super cold nitrogen recreates.
+MinecraftFTW123 The nitrogen was fully vaporized, that is gaseous, so it was. The Earth's atmosphere is 78% nitrogen, which is no more visible than is oxygen. You see clouds in the sky when droplets of liquid water have condensed onto dust particles. Water is always present in the atmosphere, but is also invisible in its gaseous state.
+Jackie Gonzalez The fog over the pool is precisely the same as a cloud in the sky, apart from it being tiny in comparison. And fog is a cloud which is at or near the Earth's surface. In all three cases, you're seeing water condensing into droplets on dust particles.
Amazing to read these comments and immediately tell who's worked with liquid nitrogen in the past and those who don't have a clue or just need to be educated on the substance. LN2 can be safely used if you take the same precautions that you would for handling any other extremely cold liquid PLUS a little common sense!
This has to be a prank of some sort? Can a chemist confirm what would happen in reality if someone jumped into a pool containing liquid nitrogen, chlorine etc. ?
Neil Baker It's no prank. The liquid nitrogen starts boiling immediately and evaporates into the air (white smoke). There is no reaction of nitrogen with water due to its inertness, it's completely harmless.
Marobin66 true - except the white smoke is water vapor; fog. the nitrogen is so cold water droplets condense - it's the same principal that makes you see fog on your breath in the winter.
Neil Baker The thing that worries me here is that nitrogen is heavier than oxygen, so once it's all boiled into vapor, almost immediately, there could be a few inches above the water where there's an absence of oxygen for just a little while until the air in the room moves around a bit. Jumping in, and disappearing into the mist could have lead to passing out and no one immediately noticing.
Matt Cournoyer this quantity of nitrogen will disperse almost immediately. the risk of suffocation is almost non existent - which is why the guy holding the bowl itself, both closer to his face, for longer AND a higher concentration of nitrogen, didn't pass out. any vapor hugging the surface of the pool will be disrupted A - by the guy jumping in and B - when he comes back up. Also, nitrogen won't create an "absence of oxygen" it will just reduce the amount of breathable air - directly proportional both in time and scope to the amount added in the first place. there was no real risk here. i mean, if you want to get real creative then maybe whatever risk is created by obscuring your view of the pool or the person who jumped in - i guess he could bang his head on the bottom or if he did actually become in danger it would be difficult to see... but you could make these exact same arguments against swimming at night.
There is a video on RUclips explaining why - But in many cases, it's actually safer to handle liquid nitrogen without gloves, due to the Leidenfrost effect.
Well, think of it this way, if it stays on your gloves long enough your hands not gonna get much protection from a thin piece of rubber, your hand will freeze under it too, besides, if you get a little on your hand the leidenfrost effect means the liquid nitrogen will simply slip off of your warm hand
One things looks very risky: What if some of the nitrogen spilled or splashed on the guy when he was tossing the liquid into the pool? Seems like it would be pretty easy to get serious frostbite. He wasn't wearing any gloves or protective gear.
TG9910 I read about Leidenfrost Effect, but still , I think that the whole pool would freeze if there was sufficient amount of LN2. If you have different opinions. could you please explain it to me???
Yaffa. Y Well, you could freeze the pool but you would need to keep pouring more LN2 to cool down the water enough, otherwise the warmth of the water will make the LN boil.
liquid n2 isn't going to induce frostbite instantly; damage would take more than 5 seconds or so. Check out nurdrage's liquid n2 vid, he explains the leidenfrost effect really well.
hehe the nitrogen heated up really quick and vaporized, it would take a lot more liquid nitrogen to cool that pool even a few degrees. And breathing nitrogen vapor is fine as long s you get some oxygen. about 70% of the air you breath is nitrogen already.
because u can choke if there isnt enough oxygen. If the nitrogen smoke acts like a blanket on the surface of the water, when you come up to breathe, you might not be able to get enough oxygen. Also, may i ask another question? wat about if u use dry ice? and swim while it is still "melting"? wouldnt it be bad if u step on one? both can cause skin irritations/ problems right?
Rei Shinnai Well the dry ice IS actually dangerous because CO2 displaces oxygen and you could suffocate as you mentioned, but nitrogen and oxygen do not displace one another, they mix, so as long as the surface over the pool started with enough oxygen to breath, the nitrogen would mix with it instead of displacing it, you might get less than normal, but it would take a crap ton more than a bowl's worth of liquid nitrogen to displace even a fifth of the oxygen over the pool and it would very quickly be forced to mix with the rest of the atmosphere as they are of roughly the same weight. CO2 however is heavier than the atmosphere and will linger on the water much longer before being absorbed into the air and so you do run a real risk of running out of oxygen....if there is a lot of dry ice in the water anyway.
TheNewsDepot Curiosity question here when you throw LN2 into the pool the smoke you see is water vapor correct. Pools are treated with chlorine and if you boil water with chlorine in it the chlorine is released as a gas wich can be deadly is chlorine gas released in this reaction since the water is essintely flash boiling
@DinoRawRainbow the liquid nitrogen was only on the surface. you can put your hand in liquid nitrogen if you remove it very fast. its just like a flame... you can run your hand through it without being burned. so when she jumped in she fell through the nitrogen fast enough to not get frozen and her impact pushed the nitrogen away from her so when she came up she was not in the nitrogen
That's an interesting question, but possibly the wrong one. For an example, at the peak of Mt. Everest the percent Oxygen in virtually unchanged from that of sea level. The main difference, and the reason climbers are required to carry their oxygen canisters with them, is that because the air is thinner, there is less total Oxygen available to them. Percentage is relative to the entire volume of air at any specific altitude, and as the total pressure decreases, so does the total Oxygen quantity.
@QEDgauge the boiling point for nitrogen is so low that the temperature probably didn't even change. you'd just have a cloud of denser nitrogen near the surface, which isn't all that big a deal, our atmosphere is already ~78% nitrogen
It's not bad in itself: nitrogen is naturally occurring in your body and the atmosphere. The reason liquid nitrogen is a problem is because the temperature required to keep nitrogen in a liquid form is so cold it will burn your skin. Doctors use it to freeze off warts all the time (I had it done on my face 4 times as a child, and it wasn't pleasant), as well as for flash preservation.
Mind you thats several/multiple jars of N3. It's clear from the size of the cloud that it displaced a lot of air. For clarities sake, the Nitrogen did NOT react with the Chlorine. Its true that if it was Ammonia it could have made something like Nitrogen Trichloride, but not with N3. The amount they dumped in this video, does not look to be especially risky (though if they had any trouble breathing, they should get out)
Nitrogen isn't poisonous. When it dissipates and displaces the oxygen and the levels drop is when it is dangerous. In an area this size however for that amount of nitrogen, it dissipates adequately. I still wouldn't recommend sitting in those clouds taking deep breaths, but as long as you have a higher O2 concentration air source available nearby, you will be fine.
@iRainSunshinee nope, the liquid nitrogen only scattered on the surface of the water, it didn't sink into it. If it did, you would see the water being turned to ice.
@Grivahri only problem is that the leidenfrost effect only works for a very little amount of time, soit being poured on your hand would only last a very short amount of time, if his face landed in it, not only would a portion be possibly submerged in it, but gravity would be against him in getting his face out of it, possibly leading to very severe burns, but most likely not death...
@zocom009 I actually read an article about a group of scientists trying to promote this idea. You use liquid nitrogen to smother the fire, and you can put the fire out without the building or contents of the building suffering water damage. Brilliant idea for fire in places like libraries and museums.
Lol, it can be very dangerous, but for short durations, and not too great an amount, I would suspect anything too damaging. You can actually submerge your hand in liquid nitrogen for a short time without any actual damage. It's called the Leidenfrost effect. Because the evaporation point is so low, your hand evaporates the liquid nitrogen in its immediate vicinity so quickly that it creates an insulating buffer around your hand. You can do the same thing with a hot pan, and little bit of water
Actually, there probably wouldn't be any liquid yet, because the temperature difference would have caused all, or most of it to evaporate on contact since it was splashed out there like that.... And even if some droplets survived for a short time, they would repel themselves away from the swimmer, due to the leidenfrost effect. The gas produced by coming into contact with something as warm as a human body creates a barrier between the skin and the liquid for a while.
@marisoltrejos All those clouds are nitrogen gas. It displaces the oxygen in the room. You are not supposed to use Liq Nitrogen Without good ventilation.
@tgseason12 I got liquid nitrogen poured on my hand in chemistry class as part of a demonstration. My hand was fine. That was because of the huge difference in temperature. So his injuries would probably be minor.
This is STILL cool! How's it feel owning one of the oldest profiles on YT? My first was from 2007, but when that shitty Google+ came, it messed up my account somehow! Haha, it still exists though, and it's among my YT "Subscriptions". 😄
It's not that dangerous. It's chemically inert, and contact with water at that temperature would almost instantly evaporate all the LN on contact. The biggest risk is actually asphyxiating in that cloud of nitrogen, although the risk is rather small.
You need to pressure-filter the air first to remove oxygen, moisture, and CO2. Otherwise you'll be looking at frozen piping at best and liquid oxygen at worst, which is a powerful oxidizer and represents an explosion hazard.
@jammastersam he wouldn't be in any danger..it would evaporate long before it did ANY damage. The second it made contact with his feet it would just be a cold rush of smoke.
liquid nitrogen boils at -196 fahrenheit. your skin is EXTREMELY hot compared to it and will actually bead off. having it spilled on you wouldnt hurt at all, just a little cold
@halite001 After reading upon Liedenfrost I agree with you on that; however the whole pool does not need to be at 0C for it to freeze! temperature can be iregular; the nitrogen could have cooled only a small part of the pool and within that an even smaller could have lost enough heat to freeze; that doesn't happen due to liedenfrost, but not beucase of what you said
No. It might drop the temp by a TINY amount. Think about it... Pool has hundreds of litres of water, heated. It was only a small bowl of liquid nitrogen. The heat of the pool caused the liquid nitrogen to boil, which resulted in the mist.
For such a volume of air and that wide open space that is very unprobable just because of simple convection. That air over the top of the water is so cold that it pulls the top warm air with oxygen down as the nitrogen gets warmer and rises up. Even the amount of nitrogen that they have in that bowl is not enough. We do experiments in our lab, and that is almost the same amount in our big dewar. We have a closed lab and computed that it cannot displace the air in the room. They are totally safe
Amanda Jerue If you stuck your hand into a bowl on liquid nitrogen and pulled it out. You could then hit your frozen hand with a hammer and it would break like glass.
Humza Qureshi if you held your hand in liquid nitrogen for an extended period you would suffer frost burn but you can put your hand in and retract it with no injury thanks to the leidenfrost effect
Amanda Jerue Drain the pool? No. There are two dangers with liquid nitrogen : 1) it's very cold, 2) it boils back to a gas, goes into the air, and can "replace" the oxygen in the air (or at least chase it away), so you could suffocate if there's too much of it, and too little oxygen. Otherwise, nitrogen is perfectly harmless. In fact, about 78% of the air you breathe normally is composed of nitrogen.
Liam3072 one thing that makes the suffocation risk greater with N2 than with CO2 is the fact that it's not detectable to us. You're right, it's not toxic, but similar to carbon monoxide (which absolutely is toxic) we can't detect it when we breath it in. That makes both very dangerous. By contrast CO2 in the blood is what causes the urge to breath in the first place so even slight elevations of CO2 are readily detectable. n2 also doesn't disperse as readily as CO2. To be clear though, the guy tossed in, what - half a gallon - 1 gallon tops? yeah, harmless.
Jeez, I would think that the air right at the surface could easily be displaced by a colder (and therefore, denser) layer of pure nitrogen. Breathing 100% nitrogen gives no warning of asphyxia, because CO2 continues to be expired normally. She probably pulled in enough air down when she jumped, but that could have gone badly.
It's no longer liquid, its converted into nitrogen gas. The 'air' we breath is already 80% nitrogen gas. If she went and swam in the cloud and breathed it it that would be dangerous, because that is almost pure nitrogen. When she jumped in she pushed the cloud of nitrogen out of the way, so long as she avoids the could she's good.
So long as you avoid the cloud you're good. The cloud is the only area where you're going to have a lack of oxygen, as it will be almost 100% nitrogen.
In Florida, in a town called Kissimmee, the use nitrogen to make ice cream. The store is currently called Boola. Have you ever tried ice cream with actual pieces of fruit, chocolate or even coffee in it? Not to mention the marshmallow, Oreo cookies, and cinnamon.
I don't think he would have been harmed if he fell in face first. He'd have to submerge himself into the actual liquid nitrogen. Once it was introduced to the pool which is much warmer, the liquid nitrogen boiled and evaporated (which is why this is all foggy). The pool might be kind of cold though.
water take a ridiculous amount of energy to heat up its probably one of the hardest liquids to heat. The same goes for cooling the water will hold a certain amount of energy at a certain temperature so if this water is at room temp it might get cooled down like 1-2 degrees maybe
It's not that unreasonable. Looks like the bowl is metal, so it would extremely cold. seeing as the person's hands were in constant contact with the bowl, wearing something to cover them is a good idea. The liquid nitrogen would actually mostly evaporate before hitting the guy's feet, and the little that did make it would be dissipated via the leidenfrost effect. It's about contact time.
@TheOverkill102 Thank you for -- finally -- a coherent and well versed response. I concede that I should have chosen a more appropriate word. Instantly implied something on the order of a millisecond, or less, and that is incorrect. However, I don't know if I'm buying seconds. I work with liquid N2, and simply removing my brain tissue samples from the LN2 freezer hurts, painfully, without gloves. 1s tops, or you are in trouble. There are videos corroborating this, as well.
@xriscross1 Yeah. This probably made part of the pool freeze, but only a small part which let it melt fast. Also this stuff is so cold it probably made the pool flash freeze or something. It probably didn't become ice because the stuff was too cold to properly form ice, which is usually formed slower than that.
Liquid nitrogen just turns to gas when it hits something warm - especially pool water. It was probably completely boiled away immediately, having no effect on the water.
+I never tell you my name not very. think about it in terms of total volume - that guy dumped what - a gallon or two into the pool? compared to tens of thousands of gallons in a pool that rapidly boiling nitrogen (a process which is certainly endothermic) isn't going to have time to suck up too much heat before its gone :-)
A bowl of liquid nitrogen (LN2) like that would've boiled off within seconds. It takes a gallon of LN2 to just barely freeze a gallon of room-temp water because LN2's heat capacity and heat of vaporization are so low. Splashed across a few thousand gallons of water? There might be a chilly spot of water.
@Thelastolympian11 "liquid dry ice" Uh, no. CO2 has no liquid form at 1atm. It's called dry ice because it goes immediately from solid to gas with no liquid phase in between. And that little amount of LN2 would not have affected the temperature of the pool much, if at all.
The Nitrogen itself is not toxic the dangerous part is that the took nice deep breaths of the nitrogen which in turn didn't allow the right amount of oxygen to the brain.

Mind you thats several/multiple jars of N3. It's clear from the size of the cloud that it displaced a lot of air. For clarities sake, the Nitrogen did NOT react with the Chlorine. Its true that if it was Ammonia it could have made something like Nitrogen Trichloride, but not with N3.
The amount they dumped in this video, does not look to be especially risky (though if they had any trouble breathing, they should get out)
They did this at my friends school with dry ice. Somebody slipped in so 2 other students jumped in to help him, all three of them died.
Nitrogen isn't poisonous. When it dissipates and displaces the oxygen and the levels drop is when it is dangerous. In an area this size however for that amount of nitrogen, it dissipates adequately. I still wouldn't recommend sitting in those clouds taking deep breaths, but as long as you have a higher O2 concentration air source available nearby, you will be fine.
@iRainSunshinee nope, the liquid nitrogen only scattered on the surface of the water, it didn't sink into it. If it did, you would see the water being turned to ice.
saw a video of 8 people getting hospitalized for doing the exact same thing
The first liquid nitrogen video on RUclips
@Grivahri only problem is that the leidenfrost effect only works for a very little amount of time, soit being poured on your hand would only last a very short amount of time, if his face landed in it, not only would a portion be possibly submerged in it, but gravity would be against him in getting his face out of it, possibly leading to very severe burns, but most likely not death...
@1timeWasEnough it rapid boiled off, the temp of the pool is probably almost the same as it was before.
*The algorithm has spoken, you shall be recommended*
@zocom009 I actually read an article about a group of scientists trying to promote this idea. You use liquid nitrogen to smother the fire, and you can put the fire out without the building or contents of the building suffering water damage. Brilliant idea for fire in places like libraries and museums.
Lol, it can be very dangerous, but for short durations, and not too great an amount,
I would suspect anything too damaging.
You can actually submerge your hand in liquid nitrogen for a short time without any actual damage. It's called the Leidenfrost effect. Because the evaporation point is so low, your hand evaporates the liquid nitrogen in its immediate vicinity so quickly that it creates an insulating buffer around your hand. You can do the same thing with a hot pan, and little bit of water
Actually, there probably wouldn't be any liquid yet, because the temperature difference would have caused all, or most of it to evaporate on contact since it was splashed out there like that.... And even if some droplets survived for a short time, they would repel themselves away from the swimmer, due to the leidenfrost effect. The gas produced by coming into contact with something as warm as a human body creates a barrier between the skin and the liquid for a while.
@marisoltrejos All those clouds are nitrogen gas. It displaces the oxygen in the room. You are not supposed to use Liq Nitrogen Without good ventilation.
Yup, those onlookers look CRAZAY!
@tgseason12 I got liquid nitrogen poured on my hand in chemistry class as part of a demonstration. My hand was fine. That was because of the huge difference in temperature. So his injuries would probably be minor.
This is STILL cool! How's it feel owning one of the oldest profiles on YT? My first was from 2007, but when that shitty Google+ came, it messed up my account somehow! Haha, it still exists though, and it's among my YT "Subscriptions". 😄
Oldest video I have seen on RUclips 10 years wow!
It's not that dangerous. It's chemically inert, and contact with water at that temperature would almost instantly evaporate all the LN on contact. The biggest risk is actually asphyxiating in that cloud of nitrogen, although the risk is rather small.
You need to pressure-filter the air first to remove oxygen, moisture, and CO2. Otherwise you'll be looking at frozen piping at best and liquid oxygen at worst, which is a powerful oxidizer and represents an explosion hazard.
@jammastersam he wouldn't be in any danger..it would evaporate long before it did ANY damage. The second it made contact with his feet it would just be a cold rush of smoke.
Whoooeee! Inside footage of the best of geek parties. Hugh must be weeping.
the nitrogen immediately evaporates. Highly recommend doing this yourself. LN is cheaper than milk! make sure to jump in after like in the video.
i bet the guy who jumped in felt cool.
Anonland It was a girl
The title must be "How to Hide Your Swimming Pool Using Liquid Nitrogen In Case Of Alien Invasion"
now this would be a great way to make a movie.
liquid nitrogen boils at -196 fahrenheit. your skin is EXTREMELY hot compared to it and will actually bead off. having it spilled on you wouldnt hurt at all, just a little cold
@Twilightman67 no...no it really doesnt, we live with air around us and air is 70% nitrogen, this is just colder
We back at it again with very old random videos as usual in recommendation
My recommendations do be kickin' again tho
@halite001 After reading upon Liedenfrost I agree with you on that;
however the whole pool does not need to be at 0C for it to freeze! temperature can be iregular; the nitrogen could have cooled only a small part of the pool and within that an even smaller could have lost enough heat to freeze;
that doesn't happen due to liedenfrost, but not beucase of what you said
No. It might drop the temp by a TINY amount.
Think about it... Pool has hundreds of litres of water, heated. It was only a small bowl of liquid nitrogen. The heat of the pool caused the liquid nitrogen to boil, which resulted in the mist.
For such a volume of air and that wide open space that is very unprobable just because of simple convection. That air over the top of the water is so cold that it pulls the top warm air with oxygen down as the nitrogen gets warmer and rises up.
Even the amount of nitrogen that they have in that bowl is not enough. We do experiments in our lab, and that is almost the same amount in our big dewar. We have a closed lab and computed that it cannot displace the air in the room. They are totally safe
usually that;s fog machine and frozen co2. i think liquid nitrogen is not only more dangerous to handle, it's also more expensive.
so it cant hurt you? i thought they were gonna have to drain the pool
Amanda Jerue If you stuck your hand into a bowl on liquid nitrogen and pulled it out. You could then hit your frozen hand with a hammer and it would break like glass.
Humza Qureshi if you held your hand in liquid nitrogen for an extended period you would suffer frost burn but you can put your hand in and retract it with no injury thanks to the leidenfrost effect
Scottimnot what about your finger
Amanda Jerue Drain the pool? No. There are two dangers with liquid nitrogen : 1) it's very cold, 2) it boils back to a gas, goes into the air, and can "replace" the oxygen in the air (or at least chase it away), so you could suffocate if there's too much of it, and too little oxygen.
Otherwise, nitrogen is perfectly harmless. In fact, about 78% of the air you breathe normally is composed of nitrogen.
Liam3072 one thing that makes the suffocation risk greater with N2 than with CO2 is the fact that it's not detectable to us. You're right, it's not toxic, but similar to carbon monoxide (which absolutely is toxic) we can't detect it when we breath it in. That makes both very dangerous. By contrast CO2 in the blood is what causes the urge to breath in the first place so even slight elevations of CO2 are readily detectable.
n2 also doesn't disperse as readily as CO2. To be clear though, the guy tossed in, what - half a gallon - 1 gallon tops?
yeah, harmless.
Jeez, I would think that the air right at the surface could easily be displaced by a colder (and therefore, denser) layer of pure nitrogen. Breathing 100% nitrogen gives no warning of asphyxia, because CO2 continues to be expired normally. She probably pulled in enough air down when she jumped, but that could have gone badly.
"Twenty bucks for the first person to jump in!"
It's no longer liquid, its converted into nitrogen gas. The 'air' we breath is already 80% nitrogen gas. If she went and swam in the cloud and breathed it it that would be dangerous, because that is almost pure nitrogen. When she jumped in she pushed the cloud of nitrogen out of the way, so long as she avoids the could she's good.
So long as you avoid the cloud you're good. The cloud is the only area where you're going to have a lack of oxygen, as it will be almost 100% nitrogen.
Every guest at the holiday inn gets a free bowl of liquid nitrogen.
In Florida, in a town called Kissimmee, the use nitrogen to make ice cream. The store is currently called Boola. Have you ever tried ice cream with actual pieces of fruit, chocolate or even coffee in it? Not to mention the marshmallow, Oreo cookies, and cinnamon.
Did someone really say they set the pool on fire?
@DRcatscratch liquid nitrogen will revert into gas when heated and the water is simply too much to be frozen so nothing should be damaged anyway.
I don't think he would have been harmed if he fell in face first. He'd have to submerge himself into the actual liquid nitrogen. Once it was introduced to the pool which is much warmer, the liquid nitrogen boiled and evaporated (which is why this is all foggy). The pool might be kind of cold though.
water take a ridiculous amount of energy to heat up its probably one of the hardest liquids to heat. The same goes for cooling the water will hold a certain amount of energy at a certain temperature so if this water is at room temp it might get cooled down like 1-2 degrees maybe
i'm glad she didnt die of asphyxiation
It's not that unreasonable. Looks like the bowl is metal, so it would extremely cold. seeing as the person's hands were in constant contact with the bowl, wearing something to cover them is a good idea. The liquid nitrogen would actually mostly evaporate before hitting the guy's feet, and the little that did make it would be dissipated via the leidenfrost effect. It's about contact time.
Looks like this took place at the Sturbridge Host in MA.
@TheOverkill102 Thank you for -- finally -- a coherent and well versed response. I concede that I should have chosen a more appropriate word. Instantly implied something on the order of a millisecond, or less, and that is incorrect. However, I don't know if I'm buying seconds. I work with liquid N2, and simply removing my brain tissue samples from the LN2 freezer hurts, painfully, without gloves. 1s tops, or you are in trouble. There are videos corroborating this, as well.
@xriscross1
Yeah. This probably made part of the pool freeze, but only a small part which let it melt fast. Also this stuff is so cold it probably made the pool flash freeze or something. It probably didn't become ice because the stuff was too cold to properly form ice, which is usually formed slower than that.
Don't mind me, I'm just carrying liquid nitrogen wearing flip-flops
nothing better than an anime convention
Liquid nitrogen just turns to gas when it hits something warm - especially pool water. It was probably completely boiled away immediately, having no effect on the water.
Last saw this video in 2006 when it only had a couple thousand views.
No it evaporates so quickly that it doesn't even feel that cold, at least no enough to freeze you
man that guy wouldnt have even finished that $20 offer if i was there
I wanna know how cold that pool will be
+I never tell you my name not very. think about it in terms of total volume - that guy dumped what - a gallon or two into the pool? compared to tens of thousands of gallons in a pool that rapidly boiling nitrogen (a process which is certainly endothermic) isn't going to have time to suck up too much heat before its gone :-)
10 years on, and people still don't get that the "Who wants to see the pool on fire?" line was a joke. XD
this is really old 16 years ago??
A bowl of liquid nitrogen (LN2) like that would've boiled off within seconds. It takes a gallon of LN2 to just barely freeze a gallon of room-temp water because LN2's heat capacity and heat of vaporization are so low. Splashed across a few thousand gallons of water? There might be a chilly spot of water.
I added liquid soap to my ix 20 hyundai windscreen wash, now it's gunged up. I've syphoned, put hot water, tried reverse blowing, nae good. help.
@Thelastolympian11 "liquid dry ice"
Uh, no. CO2 has no liquid form at 1atm. It's called dry ice because it goes immediately from solid to gas with no liquid phase in between.
And that little amount of LN2 would not have affected the temperature of the pool much, if at all.
I wish there was a underwater cam.
@SeriousBlack2 She's perfectly safe, you can pour liquid nitrogen directly on your skin in small amounts because it boils so rapidly.
The Nitrogen itself is not toxic the dangerous part is that the took nice deep breaths of the nitrogen which in turn didn't allow the right amount of oxygen to the brain.
