I sure wouldn't stand around gawking. It seems to me the real danger from
this "explosion" would not be nitrogen narcosis or asphyxiation, but
frostbite or outright freezing. How would you like to be in the path of an
expanding, boiling mass of liquid nitrogen?

I suppose this really belongs in the shop pranks but...

A co-worker had purchased a brand new pair of safety shoes
from the shoe van that comes around to work periodically.

Later that day he was filling an LN2 tank and the boil-off
was dripping on the floor, and froze his shoes. When he
went to walk away, the soles cracked - right across the
insteps.

The van had not left yet for the day, so he went back there
and said "hey, look what happened to these brand new shoes!"

"Oh my god, that must be some kind of manufacturing defect"
was the response, and they gave him a brand new pair of
shoes in exhange for the 'defective' ones.

So you think it's funny that someone cheated the shoe salesman and
someone else had to pay for his own carelessness?


Another fun-n-games is to wait until the mark is about
to re-enter his office - and pour a couple of quarts of
LN2 into his chair. The look when he comes in and finds
his seat cushion frosted and smoking is amazing. Reverse
hot-foot if you will.

You're about as funny as a fart at a funeral.
