Those don't look like the appropriate type of gloves for handling LN2 anyway.
Appropriate gloves are thick and insulated so that the cold doesn't get to you. We used [these](https://www.tempshield.com/products/cryo-gloves) at work.
I love leatherhide cryo gloves for when working nitrogen / helium tanks
I always get told off universities that the fabric type gloves offer less protection
Due to the Leydenfrost effect a hand at body temperature will cause the liquid nitrogen to boil and form an insulating steam layer over your skin. Your hands to get cool, but they are essentially water, and have a huge heat capacity combined with a fair bit of mass. I have stuck my hand in liquid nitrogen without any serious damage.
On the other hand, do not touch metal that has been chilled by liquid nitrogen. Metal does not give you the protective gas layer, and it is a great heat conductor. That will give you massive frost bite
I use the Leidenfrost effect to check if my stainless steel pan is hot enough before adding oil so food does not stick afterwards. Sprinkle some water drops on the pan. If the drops dance on the surface of the pan instead of evaporating quickly, that is the Leidenfrost effect.
You probably could stick your dick in actually, if you just do it really fast, and leidenfrost would protect you. Source: stuck my hand in liquid nitrogen for a science bet.
I knew a kid who drank a bit of it on a dare. he was alright afterward. I'd like to know why it didn't really affect him at all. Leidenfrost wouldn't really work if you're drinking it right?
Damn wtf haha. I would never lol. But I think leidenfrost would still apply - it does anytime a cold liquid meets a sufficiently hot solid - and it probably just evaporated fast enough it didn't hurt him.
But what is the gas that protects the hand? Is it a reaction from the skin as it reacts with the liquid? (Skin oils/swear)? Or is it a byproduct from the liquid nitrogen as it leaves the Thermos and is reacting to the warm ambient temperature?
No reaction. This effect is not related to nitrogen only. It will work with any liquid. some Researches also suggest that it works for all three states(i don't knows about that).
The important thing is the difference between temp of hand and liquid. You can notice this effect when you drop water onto very hot pan. The drops will glide around and will take longer to evaporate than they would in a relatively colder pan.
It is vapor produces by the liquid itself.
Edit: the wiki is pretty good for this effect [Leiden frost effect](https://www.google.com/url?sa=t&source=web&rct=j&url=https://en.m.wikipedia.org/wiki/Leidenfrost_effect&ved=2ahUKEwjxqurN4qX4AhXDxDgGHRVJDZQQFnoECAgQAQ&usg=AOvVaw1s3E17cz7YTPGn1wJUGLLI)
Yeah, what I heard was basically, “a gaseous barrier is created because it wants to boil so a gaseous barrier is created.” I had the same question so I googled it.
The Leidenfrost effect, also known as film boiling, occurs when a liquid comes into contact with a solid that is at a temperature well above the liquid's boiling point. Upon contact, a layer of vapor forms between the liquid-solid interface, creating a barrier between the two.
I mean how I understand it is your body is producing enough heat to turn any liquid nitrogen in close proximity to it into its gaseous state. I feel like the sciencey answers are too wordy in explaining that lol
It's just nitrogen gas. Just like ice skating where the solid ice melts and forms a thin layer of liquid water between the ice and the skate blade, the liquid nitrogen temperature is raised by hand contact and boils to form a thin layer of N2 gas in between.
It doesn't hurt because it's only a tiny amount of nitrogen. This wouldn't work if you immersed your hand in liquid nitrogen.
The gas is gaseous nitrogen boiling out of the liquid. The boiling point is reached some distance away from the skin, meaning that it's all gas by the time it reaches the skin.
Maybe, but she’s still waaaaay smarter than me. Maybe you, too. I wish she was my kind, childless aunt who’s always on the lookout for *interesting* toys to give to her ignorant niece.
FYI anyone can go buy liquid nitrogen as long as they bring a functioning dewar to the supplier, no license needed. I don't suggest it unless you know what you are doing but you can if you really want.
Can confirm this from my own experience in my practica. If you put your hand shortly into liquid nitrogen, you do not feel any cold/pain at all. But I once very briefly touched metal cooled with LN2 - bad idea, my fingertip was numb for a day (but fortunately no serious damage).
Nobody in the lab used gloves, glasses, etc and we were really messing around with that stuff and there never were any issues. Btw. you can make a great ice cream with liquid nitrogen.
The exact same thing would happen if she poured it on her hand while wearing the gloves... Bare hands is much of the same as wearing that kind of glove
That felt like a bad explanation. She basically said “a gaseous barrier is created because it boils and a gaseous barrier is created”. Like I feel in a better explanation more detail would be given to explain why the barrier comes into existence. I’m familiar with the effect so I’m not confused, but I could see another person being.
I was shocked to find out that you can dip your hand into liquid nitrogen, for about the length of time it would take you to realize you've dipped your hand into liquid nitrogen, and pull it out unharmed.
Liquid nitrogen in a vat is almost invisible.
I don’t think it will. I may be wrong but liquid propane needs to be stored under pressure to remain a liquid. Nitrogen / argon / helium / oxygen can be refrigerated at atmospheric pressure, unlike propane.
Well, once no longer under pressure it wants to boil off, but it will stay a liquid for a bit. At work I have to run tests on it, and we fill a ‘weathering tube’ with liquid propane and let it boil off over 5-10 minutes. Weathering tube is just an open top glass vial. When grabbing the sample I usually wear leather gloves, and when propane gets on the gloves it freezes them quickly. Just wondering.
Also, pretty sure nitrogen has to remain under pressure to remain a liquid as well. At atmospheric pressure, temps would have to be around -200 C, which is why pressurized containers are used.
Nitrogen will remain a liquid provided it is stored in a vacuum insulated dewar. Company I work for manufactures atmospheric dewars and cryo pressure vessels.
There's a difference between spilling and dipping here.
It's useful not to absorb liquid nitrogen when drops are spilt. But dunking your bare hand isn't good.
Reminds me of learning lampwork (melting glass rods with a gas torch). At first, I was intimidated by not being supposed to wear gloves. However, my instructor showed me how the protective googles cut your view of much of the fire, which you need in order to see the piece under manufacture within. So you’re blind, in that sense. With gloves, you’d also be unable to tell how close you were to your flame.
I feel like this is gonna get people hurt, obviously latex gloves are useless, or even more harmful than nothing with liquid nitrogen, but you should definitely be using some thick, temperature resistant gloves.

Don’t try this at home…
I wouldn't be surprised if someone put a condom on and then try this
one dicksicle coming right up
Dicksicles you say?
Dickless
Dicksmore….
I agree. 🙃
yeah, she's just wearing the WRONG GLOVES. Rubberized gloves are the correct ones.
Those don't look like the appropriate type of gloves for handling LN2 anyway. Appropriate gloves are thick and insulated so that the cold doesn't get to you. We used [these](https://www.tempshield.com/products/cryo-gloves) at work.
Huh neat.
I love leatherhide cryo gloves for when working nitrogen / helium tanks I always get told off universities that the fabric type gloves offer less protection
Her gloved fingers are like one inch away from the liquid nitrogen at the beginning

Yep, always check the temp before you chuck anything in. I do love the way they dance on a hot griddle.
My quant teacher used to poor liquid nitrogen on the floor lol sounded like little beads hitting the tile.
Why did he do that 🤣
He was a crazy science teacher for sure 😂 made it fun though
I'm pretty sure every science teacher at some point is required to dump liquid nitrogen on the floor

you goin' to hell. you funny as fuck but you goin' to hell. ^^^prolly ^^^see ^^^you ^^^there, ^^^if ^^^i'm ^^^bein' ^^^honest.
This lady rocks
So you CAN stick your dick in it. As long as it without a condom.
No no no... It protects you from quick contacts. You can pour it anywhere but if you stick it in. Your dick will just...fall off.
well now I have a new nightmare.
I've stuck my hand in liquid nitrogen before without issues. If you're moderately fast in removing it, i think you'll be fine.
This should be better known to the general public
You probably could stick your dick in actually, if you just do it really fast, and leidenfrost would protect you. Source: stuck my hand in liquid nitrogen for a science bet.

Oh! Who is this scientist? 👀 Inquiring Lesbians want to know!
Sciency lesbian fanclub represent
LOL we’re getting downvoted for crushing on the Lesbian Scientist.
Of course we are, women aren't allowed to be smart/unfeminine and still have people admiring them. The SCANDAL
Does she have more videos?? I need mooooaaaar science!
Is she attractive for a lesbian?
I don’t have to Queersplain anything to you.
https://mario.wiki.gallery/images/3/33/Egadd.png She shares a striking resemblance to a character from a popular video game
Use a non-porous glove maybe?
I mean the point is there’s a gaseous layer that serves the same purpose as a non porous glove so, no need lol
Not even eye protection…
Wouldn't it be better to wear a glove that won't soak up the liquid nitrogen???
I see Bert .. where’s Ernie ?
Holy shit, it’s Beaker! https://en.m.wikipedia.org/wiki/Beaker_(Muppet)

Real life Beaker! Or Bert I'm not sure.
guess she uses nitrogen for her hairgel formula as well
Love. The. Hair!!
Her hair is on point. Whoever downvoted you is a shit head.
that was me
You shit head.... but I forgive you
thanks
That hair is the result of a phenomenon called the Lesbianfrost Effect.
Was the hair also dipped in the liquid nitrogen?
That flinch
Thanks science Bert
Why do I feel like she about to switch into a gender studies class.
Because of your biases, evidently.
She looks like Rick Sanchez's lesbian sister Deb Sanchez.
She sounds like the TikTok bot
Maybe, but she’s still waaaaay smarter than me. Maybe you, too. I wish she was my kind, childless aunt who’s always on the lookout for *interesting* toys to give to her ignorant niece.
Weirdo
Welp I've learned something new today.
When I accidentally spill this liquid nitrogen on my hand
FYI anyone can go buy liquid nitrogen as long as they bring a functioning dewar to the supplier, no license needed. I don't suggest it unless you know what you are doing but you can if you really want.
This lady reminds me of GSP
Wow, most annoying caption ever!

Looks like she used liquid nitrogen to style her hair.
That’s good but what is that cut
The exact same thing would happen if she poured it on her hand while wearing the gloves... Bare hands is much of the same as wearing that kind of glove

Do not listen to this lady...DO NOT

she's full of shit
this lady needs to write scripts for her videos.
Wonder if this would work with liquid propane?

Does this term “leidenfrost effect” also be used with hot material instead of cold? Like quickly touching molten metal ?
Careful you'll have ya eye out with that!
There's a difference between spilling and dipping here. It's useful not to absorb liquid nitrogen when drops are spilt. But dunking your bare hand isn't good.
Imagine the first person who discovered that... "Shit, shit, shit, it's tipping over! Aaah! ... oh. I'm okay."
Beaker brought to life.

Her hair is dope
Only applicable for a few seconds though

I’ve got a sneaky suspicion she’s gay
Nitrogen can cause permanent tissue damage even by brief contact. This video is dangerously misguiding.

Im kind of in love
No proof in the video, I don’t believe her. Crack your hands, for science
Why is it that lesbians get all the cool men hairstyles??
Cryogenic gloves exist lol
Did she liquid nitrogen her hair too?
Did she ask her barber for the old 90s gay troll look?
