Liquid nitrogen at the doctor
No real point to this but I wanted to post anyways because it is kinda cool. Went to the doctors office with my wife today because she had this spot on her ear that was bothering her. Well the doctor wanted to freeze it with liquid nitrogen to get rid of it. Well of course my ears perked right up because to be honest this was going to be the same time I was even in the same room as this *cool* stuff. I asked her to pack some up for me to take home. She laughed and said she wished she could but did not have anything to transport it with. But she brought in a styrofoam cup about half full of it. She used a quetip to apply it to the spot on the ear three times. Then handed me the cup and said "I know the geek inside you wants to play with it.". Our doctor knows us well. But the bummer part was that I did not have anything to put in it. So since the only thing I had to freeze was myself I put the quetip on my finger. ......Yes this hurt. But it was still fun. Then I was left to just watch it boil and then blow on it once in a while. But when we were leaving I handed the cup back to her since I figured I could not leave with it and it was almost gone anyways. Then she said something she liked to do with it was to pour it on the floor. I was pretty cool to watch the "fog" it kicked up and listen to the floor crackle.
Anyways, that is my story of the day. I did not get to do much with it, but it was still *cool*.
