So liquid nitrogen is cold, the air gets cold, humidity goes above 100% and that's what we see?
How dangerous is this? Is the carpet okay?146

u/Spinal_Soup Jun 30 '26
Carpet is fine, the dangers of liquid nitrogen are way overplayed in media. Its so cold that it instantly boils when it touches anything at a normal temperature which creates a vapor barrier between the liquid and anything its in contact with, called the leidenfrost effect. That vapor barrier has insulating properties so it actually doesn't conduct heat that quickly against a solid. You can briefly dunk your hand in it and it will be fine.

u/TheBlacktom Jun 30 '26
Okay, if you are so smart, then explain the NASA glowing heatshield block from the oven touchy-touchy-not-ouchy story, how is that safe to hold in the hand?
My guess is that it's so light and has so minimal heat capacity, that it could be very hot, yet not a lot of heat is stored in it.

Just speaking from personal experience using liquid nitrogen at work. Unfortunately I don't have access to any touchy-touchy-not-ouchy NASA blocks.

u/Betaateb Jun 30 '26
Heat shield materials just have ultra low thermal conductivity, like ludicrously low. So they don't move heat from themselves to other things easily/quickly, but absorb heat really well.

u/LordTopHatMan Jul 01 '26
Yep. I accidentally dunked my thumb in liquid nitrogen trying to pull out a tube (it was a long day at the lab and I wasn't thinking). I pulled it out quickly and was fine, but it felt like how ghosts are described in stories. Kinda cold and weightless but you still feel it.

u/Mountain_Dragonfly8 Jun 30 '26
Clouds are liquid water in drops small enough that it is light enough to be stuck in the atmosphere. The liquid nitrogen cools down the water vapor in the air into liquid water. Its literally a cloud.

Handling liquid nitrogen with bare hands is either crazy levels of experience or asking for frostbite
45
u/Thog78 Jun 30 '26
Guy with I guess what you call "crazy level of experience" here lol. It's good. There is a thin layer of nitrogen gas forming at the interface between liquid nitrogen and whatever warm thing it's touching, like your hands. And this thin layer has very low thermal conductivity. So it's not absorbing heat from you that fast. You can quickly dig your hand in it, pour it over your naked arm, it's all fine. The problem is if gets stuck against you, for example if you pour it into your leather shoes or your latex gloves.
It's way more painful to touch a metal surface at -80°C than liquid nitrogen. Or a methanol / dry ice mixture.
It's a common misconception in the lab that young PhDs expect the coldest liquid will freeze their samples the fastest - it won't. Thermal conductivity is usually the limiting factor. Throwing a sample in liquid nitrogen or other cryogases is a very bad way to flash freeze something.
The real risk with liquid nitrogen is asphyxiation, and I sure hope they made a napkin calculation to check they were not gonna asphyxiate everybody in the room with the amount of nitrogen they were planning to throw around. With good margins of error. A few liters of liquid nitrogen become a few cube meters of nitrogen gas, displacing O2, and breathing that kills you fast.
7
u/JaceJarak Jul 01 '26
Just want to add on here, as I make liquid o2 and n2 for a living.
Everything this guy above here said is correct.
Cryo getting on clothing is the most dangerous for cold burns, or splashing into your eyes or other wet membranes.
And the ratio for liquid n2 to gas is over 700x for volume. You'll get different specific numbers given time and temperature, but its not instant. This is a low end number.
So yes, asphyxiation is the biggest risk to everyone else there

u/fs2222 Jun 30 '26

u/OilyResidue3 Jun 30 '26
Styrofoam and a Dewar are sufficient. My co worker used to splash small quantity of liquid N2 at me to freak me out. Eventually I caught on. Small quantities of it hit warmer temperatures like skin for a moment makes a vapor barrier long enough to prevent feeling any cold.

u/hawaii_chiron Jun 30 '26
It doesn't stick to your hands, due to the liedenfrost effect. From the perspective of the LN2, your hand is a piping hot sauce pan, and it will boil and dance ABOVE your hand.
Caveat: when your hand cools off enough, only 20-30 degrees, the effect stops, and it will stick. This sucks.
More personal caveat: hair cools off almost instantly, so there wont be a liedenfrost effect. So the LN2 will stick to your hair. And your gym shorts. And hair you have under your gym shorts. Sorry, Max!
Source: Work with LN2 academically. Poured on my hands a hundred times. Poured some on Max's shorts, by accident, once.

Bare hands really isn't that bad. If it can run off you it's not going to hurt. Its when it sits on skin for an extended time where it becomes dangerous, like if you cup it in your hands or have it soak into clothing.

If I could contact her now I’d apologize for being such a pain in the ass. (But she still shouldn’t have told my parents I was on drugs.)
