A drop of Nitrogen into the lungs.. quite difficult.. it expands as soon as it comes in contact with any warm surrounding and hence boom it evaporates.. so Nick is safe..
Except that can't happen at all as the liquid nitrogen will boil as soon as it contacts the skin, plus a single expanded drop doesn't have enough volume to fill the lungs nor enough thermal effect to damage your entire lungs, plus it won't cause asphyxia.

This is a great example of the leidenfrost effect The nitrogen that gets closest to your skin boils from the heat and creates a protective barrier. It doesn't help much against prolonged exposure. It ALSO works in reverse against molten metal (but in much smaller quantities and time frames) as the metal boils the water on top of your skin to create a barrier of steam that will prevent you from getting serious injuries if you get the metal the fuck away from you fast
For anyone with liquod nitrogen at home, splashing it on your skin is fairly safe (as shown here), but be very wary of splashing any on your face. Inhaling or swallowing liquid nitrogen is extremely dangerous even in small amounts, not just due to the low temperature, but because when the nitrogen boils off, it expands to many times its original volume which can cause tears or ruptures in the lungs and stomach!
Fun fact, it is actually more dangerous to wear gloves when handling liquid nitrogen, because it will freeze the glove, which in turn will make your hand freeze a lot faster within the glove, even more so because the glove will probably stick to your skin due to the ice build up.
It's actually same effect that happens when you spill water on extremely hot surface way above boiling point of water, part that touches surface evaporates instantly and other drops are hovering on that steam cushion, same thing here, skin is extremely hot comparing to liquid nitrogen so it doesn't make contact for too long. But yeah, it's still dangerous to touch it for longer time or try to submerge hand in a container with it.

@@rortiz2519 the water in your eyes won't be as safe as your skin.

@@mayravixx25 i think it would do the same thing. When you put liquid nitrogen droplets on your hands it causes the nitrogen to boil andand vaporize and well...boiling is boiling.
@adamduane1320 it would likely create explosive boiling... basically, the liquid nitrogen could heat up so quickly that the boiling liquid mass reaches above its boiling point and spontaneously explodes. "explosive boiling or phase explosion is a method whereby a superheated metastable liquid undergoes an explosive liquid-vapor phase transition into a stable two-phase state because of a massive homogeneous nucleation of vapor bubbles. Similar to the concept of a steam engine I believe. if the heating process is fast enough that the substance cannot reach binodal curve through heterogeneous boiling, the liquid becomes superheated with its temperature above boiling point at a given pressure. System then shifts away from the binodal and continues to follow the red curve and thus approaches towards spinodal. Near the critical temperature thermodynamic properties like specific heat, density varies rapidly as shown on the figure at right. Density and entropy undergoes largest fluctuation. During this time it is possible to have a large density fluctuation in a very small volume. This fluctuation of density results in the nucleation of a bubble. The bubble nucleation process occurs homogeneously everywhere in the substance. The rate of bubble nucleation and vapor sphere growth rate increases exponentially closer to the critical temperature. The increasing nucleation prevents the system from going to the spinodal. When the bubble radius reaches the critical size it continues to expand and eventually explodes resulting a mixture of gas and droplets which is termed as explosive boiling or phase explosion".
My HS chemistry teacher used to stuff ground beef into the index finger of a kitchen glove. He'd fold his finger down when he pulled on the glove. He then dipped his finger into the liquid nitrogen, pulled it out, and smashed it with a hammer. The girls screamed and the boys cheered. He had to stop after a parent complained about it. He had been doing it for 20 years without a problem.
Liquid Nitrogen (LIN) has a second danger which is suffocation usually from boiling too much in a non ventilated space. Splashes like that can be harmless but getting a bunch soaked into your clothes can be hazardous as well. Liquid oxygen is much more dangerous due to it being oxygen. Any mix with fuels, hydrocarbons, etc will remove much need for heat to spark a flame
bro how will clothes get soaked in it, whos gonna have that much liquid nitrogen, and if somebody has it, even then the clothes would just freeze instead of absorbing it
This phenomenon is known as the leidenfrost effect: The Leidenfrost effect is a physical phenomenon in which a liquid, close to a surface that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.
Gone. Completely erased. But not forgotten jk I’m sure the videos r still around. Ik they molested his account and name but do they still have them up ?
for anyone who doesn't know, this is comparable to putting water on a really hot surface (like a fireplace). itll just skid off without cooling it down too much due to the leidenfrost effect. itll actually take longer to evaporate than water on a cooler but still boiling surface
I once touched it with my finger, if you hold it there for a split second, you most likely wont feel anything, but any longer than that, and it feels like a quick burning feeling, it went through my skin too.
Ya, it's called the leidenfrost effect, and it does protect you from liquid nitrogen, with one exception. Your skin is warm enough and thick enough that you get quite a while before the liquid actually touches you, more than 10 seconds. You can dip your finger in for a good amount of time. But your eyes do not have the same protection. A drop of liquid nitrogen in your eye is enough to cause blindness. Leidenfrost doesn't help there, so be careful around the eyes.
Someone else already mentioned that this is due to the Leidenfrost effect, but I want to build on what that is: For two materials of EXTREMELY different temperatures, there is a small safety window for touching it because a protective barrier will form. Your hand is so hot compared to liquid nitrogen that the nitrogen immediately evaporates on contact and forms a gaseous barrier to insulate you from the rest of the liquid nitrogen. This also happens with hot metals and sparks, where (I think) they’re so hot that they’ll just bounce off your body by vaporizing sweat and getting deflected by that gas
It also is important to note that it only happens if one of the objects is significantly hotter than the boiling point of the other object, not just a large temperature difference. Dropping a cup of liquid nitrogen on your hand is fine, but dropping a steel ball at liquid nitrogen temperatures on your hand is not.
@@scy07 Yeah I’ve seen the video you’re talking about. As you may know, it’s more dangerous to wear rubber gloves when working with something like liquid nitrogen because they can freeze, and now you have something really, really cold wrapped around your hands instead of brief contact with a liquid that will quickly evaporate
Nah theres no ledenfrost for metal sparks. They still burn you, it still hurts. Most of the time its extremely minor and doesnt cause any actual damage just pain. But occasionally a larger chip will make a big spark and it's usually sharp and it will both cut into you and burn you.
Just wanted to say, if the liquid nitrogen falls on it won't burn as long as it doesn't last, but if you touch liquid nitrogen in a container (dipping your finger) you won't even need to toich the miquid to burn yourself (i know that by experience) so be careful with it, not even counting the suffocation risk
no one seems to realize that the leidenfrost effect is very powerful. The leidenfrost effect occurs when a liquid comes into contact with a surface significantly higher in temperature than its boiling point. this is often observed with water, and sometimes with liquid atmospheric gases (oxygen, nitrogen, and argon)
of course, it's not so powerful as to protect the inside of your stomach from liquid nitrogen while it sits in there for an extended period of time :P The leidenfrost effect is only for brief interactions! Over time, temperature will slowly equalize between the two objects, to the point that the boiling which prevents most heat exchange will stop, and then things will *really* get hot/cold
Many are saying Leidenfrost effect, but you also have to remember another thing. It take a LOT longer for the cold to take effect then it does for heat. Hence why you can touch liquid nitrogen quickly and not even feel it but you'll get a burn instantly on a hot stove.
I work for a company that deliveries hazardous material. Liquid nitrogen is one of them. Let me tell you, I’ve had many freezer burns on my skin. LN comes in handy in the hot summer days. I spray that cold gas on my face to cool down. It’s awesome
From what I’ve seen, it would be worse to wear a glove and get it on you because the glove would freeze around your hand and the vapor barrier wouldn’t form.
i used to work with liquid nitrogen often. i think the biggest thing to keep in mind safety wise is wearing eye protection especially when pouring. it got on my skin all the time and it wasn’t a big deal, usually it just evaporates off before you feel it
The Leiden frost effect is when the temperatures of a solid and liquid are massively different, but because the solid is still warm it heats up the liquid slightly which forms a vapor barrier, blocking the liquid
For those that don't want to be milked for content: The leidenfrost effect forms a gaseous layer around your skin when it comes into contact with liquid nitrogen. Thus in short bursts nothing happens.
@@cam_luong You're kinda right but not in this context. Yes, sweat does help you prevent getting burnt in a sauna because sweating is a way for your body to cool down by releasing heat but I don't think it's related to Leidenfrost at all. The sweat once it lingers outside your body doesn't help either.
@@YY-mk4ti No, I know the two are very different. I was just comparing it so people unaware of the leidenfrost effect would have an idea of what it is.
What is dangerous with LN2 is oxygen displacement. Since N2 is denser than oxygen, the breathable oxygen can be pushed up and out of a room. My old job as a Junior Embryologist required me to work with LN2. The room had to be well ventilated and they had sensors to detect the oxygen levels in the room. If at any point the oxygen level went under 20% we were supposed to exit the room immediately. Another major warning we had, if you ever saw someone knocked out in the LN2 room, we were warned not to run into the room, because chances are you'd knock out too. Apparently the was a case where two Embryologist died because of this. Instead, we were required to call 911 if we ever saw someone knocked out in the LN2 room (thankfully never happened while I worked there)
Liquid nitrogen is actually used is many medical procedures, often directly on the skin. For example, to remove warts. I went through that procedure as a kid. It hurt a bit, but I didn’t sustain any injury. Still, wouldn’t recommend sticking any limbs in liquid nitrogen
I sometimes refuel trucks with LNG (Liquid Natural Gas). It's not as cold, but not far from liquid nitrogen in temperature. It's about -160C to -180C. And while I don't work with it in the open like this, I directly handle the equipment it touches. And that's why I use insulated gloves. Because the hose and connector gets so cold it would freeze your finger to the metal and if you try to rip it off, you'll also rip off your skin.
When I worked as a medical assistant, we’d have to pour some into a small canister occasionally for wart removal. Whenever the doctor was done, we’d dump out the remaining liquid nitrogen by splashing it on eachother for fun. The moment you forcefully splash it like that it instantly changes from a liquid to a gas and it only feels like being hit with a cool breeze. Even the head MAs liked to mess around with it. Then it just settles to the floor and disperses quick enough to never be an issue
If your cells face that much cold that fast, they WILL die, but if it just rolls right over, you might just feel the bite. Best case scenario? You have a spot of dead skin from the cold. Worst case? You lose something
I've tried pouring it on my skin aswell 😁 The vapor caused from the different temperatures creates a sort of air shield between your hand and the liquid. It does feel cold and you can't hold it for very long though.
@@hibyepeachyfans.....5300 why? it is not my primary language. I can speak in my native language without mistakes and you would know a shit what i am talking about. ;)
It’s the Leidenfrost effect. Same thing happens when you throw water on to a ripping out pan. An air bubble forms keeping the water from directly contacting the pan and causes it to skitter around it. Same thing with the liquid nitrogen. Your hand is so hot compared to the liquid nitrogen it might as well be a ripping hot frying pan.

Leidenfrost effect. Same thing that happens when you sprinkle water on a hot pan, it beads up and rolls around protecting the surface. In this scenario, your hand is the hot pan in comparison to the extremally cold liquid nitrogen.
In a science class I had, we got to touch dry ice, turns out you can touch it for around a second before it feels like sprite for your fingers (and pain)

"explosive boiling or phase explosion is a method whereby a superheated metastable liquid undergoes an explosive liquid-vapor phase transition into a stable two-phase state because of a massive homogeneous nucleation of vapor bubbles. Similar to the concept of a steam engine I believe.
if the heating process is fast enough that the substance cannot reach binodal curve through heterogeneous boiling, the liquid becomes superheated with its temperature above boiling point at a given pressure. System then shifts away from the binodal and continues to follow the red curve and thus approaches towards spinodal. Near the critical temperature thermodynamic properties like specific heat, density varies rapidly as shown on the figure at right. Density and entropy undergoes largest fluctuation. During this time it is possible to have a large density fluctuation in a very small volume. This fluctuation of density results in the nucleation of a bubble. The bubble nucleation process occurs homogeneously everywhere in the substance. The rate of bubble nucleation and vapor sphere growth rate increases exponentially closer to the critical temperature. The increasing nucleation prevents the system from going to the spinodal. When the bubble radius reaches the critical size it continues to expand and eventually explodes resulting a mixture of gas and droplets which is termed as explosive boiling or phase explosion".

This man has some balls to throw a cup of liqyid nitrogen to his face
Grant from Tkor did it first like five years ago

Some extra balls than ours😂
His balls got frostbitten after this.
My HS chemistry teacher used to stuff ground beef into the index finger of a kitchen glove. He'd fold his finger down when he pulled on the glove. He then dipped his finger into the liquid nitrogen, pulled it out, and smashed it with a hammer. The girls screamed and the boys cheered.
He had to stop after a parent complained about it. He had been doing it for 20 years without a problem.
so i could theoretically take a shower using liquid nitrogen
Well you could theoreticly use larva too
Liquid Nitrogen (LIN) has a second danger which is suffocation usually from boiling too much in a non ventilated space. Splashes like that can be harmless but getting a bunch soaked into your clothes can be hazardous as well. Liquid oxygen is much more dangerous due to it being oxygen. Any mix with fuels, hydrocarbons, etc will remove much need for heat to spark a flame
bro how will clothes get soaked in it, whos gonna have that much liquid nitrogen, and if somebody has it, even then the clothes would just freeze instead of absorbing it
I dont see the danger of suffocation in any possibility of normal use. A whole tank of liquid nitrogen probably wont do much in a regular room.
@@IBRChampionBut thats how it works. Small holes absorb liquid before the clothes freeze. So it is a hundred time worse than pouring liquid nitrogen.
@@IBRChampionspilling it on your shirt or pants:
Like those Russians jumping into a pool with liquid nitrogen, they all drowned and suffocated.
This phenomenon is known as the leidenfrost effect: The Leidenfrost effect is a physical phenomenon in which a liquid, close to a surface that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.
Isnt something similar true but with lava? Which is why you can actually move your hand quickly through falling lava without it burning you?
@@CJFX_ Not lava, falling molten metal.
you need to have your hand moist tho
@@CJFX_ Lava is way too viscous. Liquid steel works tho.
It’s like putting tiny amounts of water in a hot pan. And it kinda skids around actually like little beads or something.

for anyone who doesn't know, this is comparable to putting water on a really hot surface (like a fireplace). itll just skid off without cooling it down too much due to the leidenfrost effect. itll actually take longer to evaporate than water on a cooler but still boiling surface
Its called the Leidenfrost effect tough guy😉.... Ur welcome

I once touched it with my finger, if you hold it there for a split second, you most likely wont feel anything, but any longer than that, and it feels like a quick burning feeling, it went through my skin too.
Ya, it's called the leidenfrost effect, and it does protect you from liquid nitrogen, with one exception. Your skin is warm enough and thick enough that you get quite a while before the liquid actually touches you, more than 10 seconds. You can dip your finger in for a good amount of time. But your eyes do not have the same protection. A drop of liquid nitrogen in your eye is enough to cause blindness. Leidenfrost doesn't help there, so be careful around the eyes.
Someone else already mentioned that this is due to the Leidenfrost effect, but I want to build on what that is:
For two materials of EXTREMELY different temperatures, there is a small safety window for touching it because a protective barrier will form. Your hand is so hot compared to liquid nitrogen that the nitrogen immediately evaporates on contact and forms a gaseous barrier to insulate you from the rest of the liquid nitrogen. This also happens with hot metals and sparks, where (I think) they’re so hot that they’ll just bounce off your body by vaporizing sweat and getting deflected by that gas
@wagh Okay, thank you for the further insight and clarification
It also is important to note that it only happens if one of the objects is significantly hotter than the boiling point of the other object, not just a large temperature difference. Dropping a cup of liquid nitrogen on your hand is fine, but dropping a steel ball at liquid nitrogen temperatures on your hand is not.
Was that an older woman who said you shouldn't wear gloves when handling liquid nitrogen?
@@scy07 Yeah I’ve seen the video you’re talking about. As you may know, it’s more dangerous to wear rubber gloves when working with something like liquid nitrogen because they can freeze, and now you have something really, really cold wrapped around your hands instead of brief contact with a liquid that will quickly evaporate
Nah theres no ledenfrost for metal sparks. They still burn you, it still hurts. Most of the time its extremely minor and doesnt cause any actual damage just pain. But occasionally a larger chip will make a big spark and it's usually sharp and it will both cut into you and burn you.
You forgot to say "dont try this at home" for some viewers this warning is really important. 😂
The kind of viewers that just have liquid nitrogen lying around are the kind of viewers that know about safety.
Yeah, most people have liquid nitrogen in the closet waiting
@@dingdong2103 I do lol, I have a science fair soon
@@Felixsleftbigtoenail can you drink it, please
Omg ! It's you that worked with the TKOR team for a long time before leaving in 2019 or 2020 !
Just wanted to say, if the liquid nitrogen falls on it won't burn as long as it doesn't last, but if you touch liquid nitrogen in a container (dipping your finger) you won't even need to toich the miquid to burn yourself (i know that by experience) so be careful with it, not even counting the suffocation risk
no one seems to realize that the leidenfrost effect is very powerful. The leidenfrost effect occurs when a liquid comes into contact with a surface significantly higher in temperature than its boiling point. this is often observed with water, and sometimes with liquid atmospheric gases (oxygen, nitrogen, and argon)
of course, it's not so powerful as to protect the inside of your stomach from liquid nitrogen while it sits in there for an extended period of time :P
The leidenfrost effect is only for brief interactions! Over time, temperature will slowly equalize between the two objects, to the point that the boiling which prevents most heat exchange will stop, and then things will *really* get hot/cold
Yup
Did you copy this from some kind of textbook?
🤓

Many are saying Leidenfrost effect, but you also have to remember another thing. It take a LOT longer for the cold to take effect then it does for heat. Hence why you can touch liquid nitrogen quickly and not even feel it but you'll get a burn instantly on a hot stove.
I work for a company that deliveries hazardous material. Liquid nitrogen is one of them. Let me tell you, I’ve had many freezer burns on my skin. LN comes in handy in the hot summer days. I spray that cold gas on my face to cool down. It’s awesome
From what I’ve seen, it would be worse to wear a glove and get it on you because the glove would freeze around your hand and the vapor barrier wouldn’t form.
i used to work with liquid nitrogen often. i think the biggest thing to keep in mind safety wise is wearing eye protection especially when pouring.
it got on my skin all the time and it wasn’t a big deal, usually it just evaporates off before you feel it
It burnt didn't it.
@@SAS23456-i it stung a bit, less than getting hit with an air soft pellet but i didn’t get hit with any much bigger than a blueberry
It’s the vapor barrier that protects you. Similar to the holding a lit cigarette trick between your thumb and finger
The Leiden frost effect is when the temperatures of a solid and liquid are massively different, but because the solid is still warm it heats up the liquid slightly which forms a vapor barrier, blocking the liquid
For those that don't want to be milked for content:
The leidenfrost effect forms a gaseous layer around your skin when it comes into contact with liquid nitrogen. Thus in short bursts nothing happens.
Kinda like how the sweat around you in a sauna prevents your skin from being burnt in the hot temps
Not only liquid nitrogen though but any liquid though the temperature needed will vary.
@@cam_luong You're kinda right but not in this context. Yes, sweat does help you prevent getting burnt in a sauna because sweating is a way for your body to cool down by releasing heat but I don't think it's related to Leidenfrost at all. The sweat once it lingers outside your body doesn't help either.
@@YY-mk4ti No, I know the two are very different. I was just comparing it so people unaware of the leidenfrost effect would have an idea of what it is.
@@cam_luong I understand what you're trying to say but I don't think the sweat around you really helps from the sauna's heat.
What is dangerous with LN2 is oxygen displacement. Since N2 is denser than oxygen, the breathable oxygen can be pushed up and out of a room. My old job as a Junior Embryologist required me to work with LN2. The room had to be well ventilated and they had sensors to detect the oxygen levels in the room. If at any point the oxygen level went under 20% we were supposed to exit the room immediately.
Another major warning we had, if you ever saw someone knocked out in the LN2 room, we were warned not to run into the room, because chances are you'd knock out too. Apparently the was a case where two Embryologist died because of this. Instead, we were required to call 911 if we ever saw someone knocked out in the LN2 room (thankfully never happened while I worked there)
Stay careful
Clearly, you just take a big breath and get the person to safety instead of watching them die like a disgusting coward.
Few of us remembers Terminator 2 scene where the T1000 gets completely frozen due to the high exposition to Liquid Nitrogen.
Liquid nitrogen is actually used is many medical procedures, often directly on the skin. For example, to remove warts. I went through that procedure as a kid. It hurt a bit, but I didn’t sustain any injury. Still, wouldn’t recommend sticking any limbs in liquid nitrogen
I remember Grant Thomson demonstrating something like this and explaining the leidenfrost effect
RIP Grant 😞

We have hotdogs at the school cafeteria today!
The hotdogs at the school cafeteria:
Lmao
A layer forms due to the gas layer but it will not lasts forever if your still pouring continuously
I sometimes refuel trucks with LNG (Liquid Natural Gas). It's not as cold, but not far from liquid nitrogen in temperature. It's about -160C to -180C. And while I don't work with it in the open like this, I directly handle the equipment it touches. And that's why I use insulated gloves. Because the hose and connector gets so cold it would freeze your finger to the metal and if you try to rip it off, you'll also rip off your skin.
When I worked as a medical assistant, we’d have to pour some into a small canister occasionally for wart removal. Whenever the doctor was done, we’d dump out the remaining liquid nitrogen by splashing it on eachother for fun. The moment you forcefully splash it like that it instantly changes from a liquid to a gas and it only feels like being hit with a cool breeze. Even the head MAs liked to mess around with it. Then it just settles to the floor and disperses quick enough to never be an issue
Sounds fun
Dude just splashed it on his face with no safety goggles 💀
He’s done it several times he’s a professional
@@thatfeelingwhenyoufeel.it’s a good way to go blind, even a drop hitting your eye can cause serious damage
If your cells face that much cold that fast, they WILL die, but if it just rolls right over, you might just feel the bite. Best case scenario? You have a spot of dead skin from the cold. Worst case? You lose something
I've tried pouring it on my skin aswell 😁 The vapor caused from the different temperatures creates a sort of air shield between your hand and the liquid. It does feel cold and you can't hold it for very long though.
He really just said fuck safety. I love it.

It’s the Leidenfrost effect. Same thing happens when you throw water on to a ripping out pan. An air bubble forms keeping the water from directly contacting the pan and causes it to skitter around it. Same thing with the liquid nitrogen. Your hand is so hot compared to the liquid nitrogen it might as well be a ripping hot frying pan.
As a kid my dad had surplus liquid nitrogen, (he owns a fancy restaurant) one time I dipped a metal spoon full of sugar into the liquid nitrogen to make a homemade popsicle. I lost a small bit of my tongue that day.
A software patch named "The leidenfrost effect " is saving this man in this universe!!
I guess the Devs are working tirelessly to keep this patch bug free.
Leidenfrost effect. Same thing that happens when you sprinkle water on a hot pan, it beads up and rolls around protecting the surface. In this scenario, your hand is the hot pan in comparison to the extremally cold liquid nitrogen.
As a associate professor in chemistry I never taught my students this type of chemical handling 🙄
In a science class I had, we got to touch dry ice, turns out you can touch it for around a second before it feels like sprite for your fingers (and pain)
