LN2 and LOX
Yeah, I don't remember the exact name for the phenomenon where liquid nitrogen "distills" LOX out of the air under certain conditions, but it was something we had to really look out for when designing confined tank insulation.
I saw some show once where some people in Japan had a hair styling gimmick where they'd soak hair in cryogenic fluid and break it off to style it. The show said the fluid was liquid oxygen (!!!) I don't know how you would normally deal with liquid-oxygen-soaked hair, but I would recommend some distance to start with.
I wonder if the news guys just screwed up and said "liquid oxygen" instead of the much safer "liquid nitrogen," or even "liquid air."
