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.
