Would the human face really freeze solid in a few seconds, when exposed to -150 degrees Fahrenheit air, like the pilot of the crashed helicopter in The Day After Tomorrow? | Munipalli Akshay Paul ||

Back during college days we had a little fun with a dewar flask and liquid nitrogen. Kind of like this Someone scooped up a handful of liquid nitrogen and threw it in my face. What do you think happened? Did my face freeze solid? No. I didn’t have frostbite either. It felt like a splash of cold water for a second and then nothing, I was dry. Quite an interesting experience really. Liquid nitrogen is denser than air and has a temperature well below -150 F. It’s only about 3% as dangerous as you think, but nonetheless well above the dangers of the air you mention. You could get frostbite within minutes, the guy who doused his t-shirt in liquid nitrogen and then put it on did get second degree frostbite on his back, but you won’t freeze solid or anything like that. The greatest danger is the shock you’ll suffer from breathing in such cold air. After that it’s the frostbite and the bitter cold, yes.
