Got permanent tingling on the very tip of a pinky finger from frostbite.
Please don't do the whole "LN2 in the mouth and spit it out thing". Guess what happens if you involuntarily swallow a little?
When the fluid instantaneously expands to gas you don't burp or fart it out. It tears through your tissue planes. If you know that, but risk it anyway, that's natural selection. But if you see Hicookie do it and think it's just a fun game, then it's pretty sad when you die trying it.
