Former lab personnel here. One of the biggest things they'll say when training you on lab safety is it's deadly nature if inhaled. A single drop of liquid nitrogen in the lungs is lethal, as it expands to a massive size and basically bursts the lungs. Not perfectly accurate, but that's basically it. So funnily enough the most dangerous thing you could do is splash it in your face... Which he did...
I mean I'm sure he closed his mouth but yeah, still not a great idea. Worse idea would be to drink it, but nate isn't stupid, so obviously he's not gunna drink it
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.
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.
The Leiden frost effect, when it touches your skin it immediately boils due to the heat of your skin being too hot for the nitrogen to stay liquid and causes the nitrogen to boil, creating a "steam" barrier between your skin and the nitrogen. Therefore, you aren't actually touching the liquid nitrogen, hence not freezing your skin. However, it will still freeze your skin if left alone long enough.
@@williebrortwhat if someone can't produce the needed heat from their body to do the lidenfrost effect? as in their body is on the colder temperature side then the hotter temperature
@@jaidakhatun4568 they suffer from severe burns (yes extreme cold can cause burns wounds) or frostbite. I'm not native in English so I don't know if these are the correct terms for that.
Some safety precautions if you try this: 1: Don't let it get trapped against your skin by rings, watches, clothes, shoes, etc. 2: Make sure you are in a well ventilated area as nitrogen asphyxiation is a thing that can kill you before you even realize you are in danger. 3: Don't get it in your eyes.
@@rortiz2519 the water in your eyes won't be as safe as your skin. Your skin will reliably have an insulating layer of nitrogen because of the leidenfrost effect and that nitrogen isn't as efficient at transferring energy as the liquid so it's not dangerous in small amounts. Your eyes are still warm enough for the leidenfrost effect to occur but the water is much more likely to freeze or even make contact with the liquid nitrogen. Freezing the surface of your eyes can do some serious damage to your cornea and you can end up functionally blind. However, this is still pretty unlikely to happen and isn't really a concern considering you will most likely be able to close your eyes before any liquid nitrogen can hit your cornea. You would have to be messing around with A LOT of it before you really need to be wearing safety specs. And at that point you should have full face respirators with oxygen supply because your biggest concern will be a spill that ends up displacing all the oxygen near you and suffocating you.
The reason why is because of the leidenfrost effect. The temperature difference is so great so when there is brief contact, a protective air layer prevents direct contact and makes the liquid bounce
Leidenfrost effect. Same thing if you put droplets of water on a hot pan. The liguid vaporized on contact with the hot surface and creates a layer of vapor between the two. Thats why it looked like it was skating off his hand. The liquid nitrogen is so cold that your hand is like a piping hot pan to it.
Now I'm curious to know what happens if you put some liquid nitrogen on a hot pan instead of your hand. Would it produce the same effect or something way cooler 🤔
@@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".
Hi, I work with Liquid Nitrogen daily for my job. Liquid nitrogen is honestly just like ice cold water, but it runs RIGHT off. Now, if you hold metal that's been soaking in it until no longer boiling, you can hold it for about 3-5 seconds before that shit starts burning and you'll feel it for quite some time. Be safe.
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 ?
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.
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
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
The Leidenfrost effect! Very cool! For those that dont know what that is, its when the liquid has a "bubble" of gas around it, keeping it from making direct contact with the object. For a way to see this at home, put a few drops of water in a very hot pan and watch as the drops scatter around super fast before evaporating.
@@MRez-kl5fe the outermost layer instantly evaporates once in contact with the heat, turning into steam and flies up, every drop is its own little hovercraft. same thing applies with liquid nitrogen, in this case it just turns back into air
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.
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
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
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.
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.
The nitrogen immediately vapourises as it touches his hand, creating a thin layer of gaseous nitrogen beneath the drop of nitrogen thus not letting it touch his hand
I'm so glad that I found your channel after being a huge fan of your TKOR stuff, it brings me joy to watch these interesting videos with you in them again!
Ah the leidenfrost effect, the nitrogen is so cold that it creates a layer of vapor as it's evaporating between the actual liquid and whatever surface it comes into contact with (in this case, his hand), which is why it's safe to have quick unsustained contact without it causing damage. But like he shows, do not, under any circumstances, submerge any portion of yourself for anything more than the briefest of moments. You will take cold damage.
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)
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
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.
@@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. ;)
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.
@@kemi_smith 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.
In addition to the Leidenfrost effect keeping a barrier between the nitrogen and your skin in the event of spillage, accidentally submerging your finger into a jar of the stuff will produce this wonderfully helpful effect known as "searing pain" as your skin starts to get cold enough to suffer damage, forcing your body to not submerge your finger in it any more.
The thing is that our body is relatively hot which resist the cold of liquid nitrogen like for a touch or spill on hand or any part of body. But for too long it might affect.
anybody who has had a wart and gotten it liquid nitrogen frozen knows it hurts like hell. I had a nasty plantar wart on my foot and it hurt like hell but once it stops hurting it blisters up a lot and in some bad cases like mine it’ll fill up with blood. Don’t be worried though because it doesn’t hurt because you’ve frozen the nerves or killed them.
I'm prone to getting warts and I take the green blister beetle vesicant 10/10 times when the wart is on my foot. The liquid nitrogen treatment stings a little, but the aching pain afterwards is the worst. If its anywhere else, freezing it is way better because the pain is super manageable and the blister is not nearly as messy with freezing
Reminds me of a time when my chemistry teacher was doing an experiment that supposedly involved ‘dangerous chemicals’ and when everything was done he just poured it all on his hand
Grant demonstrated this on his channel before he passed there is such a temperature difference that it doesn’t come into contact with your skin right away but yea left there for more then a couple seconds it could mess you up
You should have explained it's due to Leidenfrost effect. That's when liquid touches something way above it's boiling point, instead of directly touching, it forms layer of gas inbetween, wich is pretty bad at conducting heat. It also lowers friction to near zero so if it's able, it will run off the surface before any major heat transfer occures, and that's why it's relatively safe. At home you can try by heating up pan way above 100C and dropping few drops of water in.
I remember going to the hospital for a covid booster, and I remember I was in the elevator and I saw a person who worked there holding a giant amount of liquid nitrogen.
I know there’s some kind of bubble around your skin keeping it safe from the liquid nitrogen, but as long as the liquid doesn’t stay long on your skin, no concern.
As long as your hands are dry !! Your pretty safe. I used to use liquid nitrogen every day. Grab it by the handfull and thrpw it across the room lol i know someone who put it down the back of someomes shirt once during service
When I worked in a butter factory thats how we kept everything cold and it was freaking miserable but it really isn't super dangerous to come into contact with briefly. It evaporates super fast so you'd literally have to submerge your body into it before it becomes a serious problem.

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
-Yo Bro, what you smoking??
-liquid Nitrogeeen
The Leidenfrost effect! Very cool! For those that dont know what that is, its when the liquid has a "bubble" of gas around it, keeping it from making direct contact with the object. For a way to see this at home, put a few drops of water in a very hot pan and watch as the drops scatter around super fast before evaporating.
why it keeping it makiing direct. contact from the object
@@MRez-kl5fe the outermost layer instantly evaporates once in contact with the heat, turning into steam and flies up, every drop is its own little hovercraft. same thing applies with liquid nitrogen, in this case it just turns back into air
@@nguyen-vuluu3150 thank you for the explanation
@@nguyen-vuluu3150
Heres a fun fact here, if you get a pan hot enough, you can even do the same thing with a water drop!
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.
Man's calling a sausage a 'hotdog' 😅
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
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?
🤓
We have hotdogs at the school cafeteria today!
The hotdogs at the school cafeteria:
Lmao
Holding the hotdog after he crumbled it was the most dangerous part of any of this
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.
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.
That's not hotdog it is colddog now 💀
The nitrogen immediately vapourises as it touches his hand, creating a thin layer of gaseous nitrogen beneath the drop of nitrogen thus not letting it touch his hand
I remember Grant Thomson demonstrating something like this and explaining the leidenfrost effect
RIP Grant 😞

@@thatfeelingwhenyoufeel.it’s a good way to go blind, even a drop hitting your eye can cause serious damage
Bro the ending is wild ☠️
Ah the leidenfrost effect, the nitrogen is so cold that it creates a layer of vapor as it's evaporating between the actual liquid and whatever surface it comes into contact with (in this case, his hand), which is why it's safe to have quick unsustained contact without it causing damage. But like he shows, do not, under any circumstances, submerge any portion of yourself for anything more than the briefest of moments. You will take cold damage.
Yea your making Grant proud. Awesome to see you doing so good. Looks like your happy and motivated again and it shows.
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
@@Leeknows.eyelash can you drink it, please
Safety was his last priority
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.
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
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.
After you fire your safety team 😂😂
"Dude fixes my nightmare in just 60 seconds"
Legends say he bought 12 tons of nitrogen before he decided to create a youtube channel

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.
@@kemi_smith 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.
@@kemi_smith 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 moms think the food is going to be when your 1 millisecond late:
Meanwhile we eat biscuits diped in it , to get the smoky effect. 🗿
In addition to the Leidenfrost effect keeping a barrier between the nitrogen and your skin in the event of spillage, accidentally submerging your finger into a jar of the stuff will produce this wonderfully helpful effect known as "searing pain" as your skin starts to get cold enough to suffer damage, forcing your body to not submerge your finger in it any more.
Never knew about the existence of "searing pain", thanks for the info!
The thing is that our body is relatively hot which resist the cold of liquid nitrogen like for a touch or spill on hand or any part of body. But for too long it might affect.
anybody who has had a wart and gotten it liquid nitrogen frozen knows it hurts like hell.
I had a nasty plantar wart on my foot and it hurt like hell but once it stops hurting it blisters up a lot and in some bad cases like mine it’ll fill up with blood. Don’t be worried though because it doesn’t hurt because you’ve frozen the nerves or killed them.
I'm prone to getting warts and I take the green blister beetle vesicant 10/10 times when the wart is on my foot. The liquid nitrogen treatment stings a little, but the aching pain afterwards is the worst. If its anywhere else, freezing it is way better because the pain is super manageable and the blister is not nearly as messy with freezing
I've never had a wart and maybe this is a normal thing but...
Who the hell freezes their wart with liquid nitrogen???
Nah but dr Paul made it look painless
I didn't think it hurt at all, but maybe I'm not remembering well 🤔 it was a long time ago.
@@CancerousSwineive had a wart and yes you do use liquid nitrogen to freeze it off the first time hurt so much
Man with beauty and brains 🎉🎉 not a common combo these days
In the lab we just picked tubes out of the LN2 by bare hands. As long as you do not try to find 20 of them at the time, you do not even feel it.

Grant demonstrated this on his channel before he passed there is such a temperature difference that it doesn’t come into contact with your skin right away but yea left there for more then a couple seconds it could mess you up

mam aap kitne ache ho aapne hamare liye itni mehnat karke sab banaya
Really thank you mam 🙂🙏🏻
You should have explained it's due to Leidenfrost effect.
That's when liquid touches something way above it's boiling point, instead of directly touching, it forms layer of gas inbetween, wich is pretty bad at conducting heat. It also lowers friction to near zero so if it's able, it will run off the surface before any major heat transfer occures, and that's why it's relatively safe.
At home you can try by heating up pan way above 100C and dropping few drops of water in.
I tried splashing my face with liquid nitrogen after watching this and now i am blind in one eye. You’ll be hearing from my lawyer soon.
I'm keeping an eye on this guy
Safe to say some people looked the other way on this👀

Love the vids Nate, keep them up!
Leidenfrost effect
Funfact:
"Leiden" means to "suffer" in german
I know there’s some kind of bubble around your skin keeping it safe from the liquid nitrogen, but as long as the liquid doesn’t stay long on your skin, no concern.
I remember grant actually doing this experiment and getting a wart. Good times.
As long as your hands are dry !! Your pretty safe. I used to use liquid nitrogen every day. Grab it by the handfull and thrpw it across the room lol i know someone who put it down the back of someomes shirt once during service
Brigham young University has probably got better stats right
When I worked in a butter factory thats how we kept everything cold and it was freaking miserable but it really isn't super dangerous to come into contact with briefly. It evaporates super fast so you'd literally have to submerge your body into it before it becomes a serious problem.
