This is the same behavior we see on moons like Titan. There is water there, but when you cool water to such a temperature it stops acting like ice and starts behaving more like igneous rock.
Can we do that with my corpse? That seems better than being struck in a coffin forever and faster than being cooked in an incinerator. Which always seemed a bit hellish to me
Hey Doug if you're reading this I'm sorry for that time in 7th grade when they did a demonstration with a racquetball in liquid nitrogen and when it shattered a piece broke into a triangle and I convinced you to stick it to your forehead for several minutes which left a purple triangle the size of a paper football for about a month.
Bare hands is the correct way to do it. The Leidenfrost effect protects your hands, but if you wear gloves they can trap the LN2 and cause serious injury. https://www.youtube.com/watch?v=67ijwSZ3gnQ
Was at work at a gas station, we had the hot plates for coffee pots. Asshole forgot to turn off an unused plate and I picked up one of the empty pots to make more coffee. They were -very- fragile, so i always used two hands and placed one on the bottom. Did not know skin could bubble like that x.x
Except the boiling liquid in this case isn't water, it's the nitrogen. As long as the hand is significantly above the boiling point of nitrogen the leidenfrost effect will cause a layer of nitrogen gas to keep forming between the hand and the liquid.
The hand will cool down very quickly: Nitrogen boils at -196°C, so the "vapour" will also still be cold. This will quickly draw heat away from the hand. And yes, the water on the hand's surface (I was referring to that) provides some heat when freezing, but then the temperature will go down.
Gloves can cause severe damage when working with liquid nitrogen. Without gloves it just splashes off your hands but with gloves it can soak in to the gloves and cause serious freezing damage. Even water tight gloves can freeze, crack and cause this type of damage.
In the lab I work in, when working with cryogenic materials (dry ice, liquid nitrogen) these types of gloves are required. But, as the hierarchy of controls tells us, PPE is the last line of defense. Gotta have a well designed system in place and not be a doof when youre using dangerous stuff
Yes, I also have to get trained annually on the levels of safety (engineering controls, administrative controls, and PPE) While PPE is the last line of defense, it is not dispensible when direct contact is a risk. I see a lack of all 3 levels here.
No PPE. No evidence of any splash guard. No mechanical device (e.g. tongs) to hold material contacting the LN2. Incorrect container type (cryo liquids should be kept in insulated dewar flasks). Overfilled container presents spill hazard.
maybe he's talking about after it was taken out? looks like he waited a fair length of time to touch the banana that was in the nitrogen with his hands, at which all the nitrogen will have boiled off by then, so maybe he's worried about the extreme cold of the banana (depending on how long it was dipped for) directly the the skin? but maybe he's not, at which point, you're correct, and ignore everything I said prior
As someone who has done similar demonstrations: you really don't want your hand frozen to a banana. It leeds to odd moments at the doctor's. Oh, and first degree frostbite (is it frostbite? I can't find a translation for "Kälteverbrennung") itches like hell when healing.
exactly, which is why I made that comment, the person I was replying to was correct only when speaking of the possibility of having liquid nitrogen splash on you, where not having gloves can save you by the leidenfrost effect (I think) but I'm more expecting the reaction video was in reply to what you're talking about, where intentionally handling something solid that's that cold could cause damage (and yes, I'm guessing frostbite is the correct term you're looking for)

Yeah, lot safer than with gloves.

Me, as I am a plumber and worked industrial stuff at the arctic circle, you get used to it. Your fingerprints gets "burned" off permanently.

Just -196°C, what could go wrong. The Leidenfrost effect will protect the hand. Briefly. Once the water is gone, the hand gets all the chill.

Then tongs
hyperchondriac
Perhaps they were talking about these. Not meant to be submerged but will protect pretty well against splashes.
And yeah, if you submerged them maybe they would crack, but that's not what they are designed to do. And as the other guy said, tongs.
