I've done the "pouring LN2 on your hand" trick, and experienced only a slight chill. The physics here appears to be that some of the liquid vaporizes to form an insulating layer of gas. While I would not blithely stick my arm in a vat of LN2, I think it could be done for a short period of time. Grabbing a metal tool at LN2 temperatures would be foolish, however. This is unrelated, but *how* much does Alcor spend yearly on LN2? I was under the impression that it was quite inexpensive. Eli Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=1313
