So this is crazy to me, anyone at DMS willing to try it? just kidding
Haha, knock yourself out. I’ve done the thing where you put a chunk of dry ice in your mouth and move it around. Unfortunately, one person accidentally got it stuck in her throat. She started gagging and puffs of cloudy CO2 were coming out of her mouth like a train. Both hilarious and scary at the same time. She was fine after, funny to look back on and laugh at.

I don’t guess I should post a link to google images Liquid Nitrogen Burns. Particularly nasty!
Let’s not do that!
Ken,

Interesting images - I would think that those injuries would result from immersion, but given the localized nature (spot burns) it looks like it just dripped on them.
This puzzles me because when I worked at NSERL, one of my jobs was refilling the liquid nitrogen dewars. Often it would spill a bit and splash on the keyboards, tabletops, etc. On several occasions I poured some in my palm and it did no damage whatsoever. Perhaps I have some kind of cryo-resistance superpower, but I thought it odd at the time. You DID have to wear special cryo resistant gloves when refilling from the main tank because the main source of potential injury was from the low temperature of the metal hose. (think tongue stuck to metal ice tray)
Also liquid nitrogen is a LOT colder (-320 F) than dry ice (-110 F)
BTW, I am NOT suggesting for a second that anyone else should try this - those photos are not fake and I can’t explain my saving throws vs. cold at +4.
Also, I agree with you about not trying the dry ice experiment as you can potentially pass out from the CO2 inhalation (hypercampnia) and have a head injury.

Yea, I actually did the ice bucket challenge with Liquid Nitrogen. @Nick and I also poured it unto tables cups etc. to show the leidenfrost effect. Those people must have poured it in a stream over the affected spots.
Yeah, after work with @Lampy and doing all the liquid nitrogen ice cream, I thin liquid nitrogen may be safer than dry ice. Dry ice likes to stick to things and cold thing sticking to people is what tends to lead to burns. I would bet those burns happened while wearing a glove and the liquid nitrogen seeping through or splashing in a and being held against the skin. Welders know all about this, this is why they don’t wear short gloves.
Good points, guys.
Also, liquid N2 sublimates (goes from liquid to gas) MUCH faster because of the difference in vapor pressure curves compared to CO2.

This just downright idiotic, and the reason we can’t have nice things anymore. Gotta protect everyone from the 0.01% like this dolt who will end up freezing his esophagus and requiring some $100,000 surgery to replace it.
Please don’t do this at home, kids.
beyond the fact it would freeze and kill your throat / stomach… what about the volume of the sold vs gas? it seems an invitation to a burst gut.
