I guess the question I should have asked is this:
What's the worst that can happen from freezing a small area of normal
skin for 10-30 seconds with a Q-tip soaked in LN2?
I used to live in an area (Rockies) that got very cold in the winter
(up to -30 once in awhile). A lot of people got minor frostbite
including me. I never had a serious problem, but then it was minor. It
just seemed to me that this would be even less dangerous. It's a much
lower temperature (-300F or so), but it's for a very short time and on
a very small area.
So, that's my question: what's the worst that can happen?
