You really don't need to enclose the lock in styrofoam. Just pouring 
enough of the stuff over the lock should do it. I've even seen "spray 
cans" that let you aim the nitrogen at a specific spot. And, if the 
nitrogen evaporates violently, you know it's cooling something. The thing 
that worried me is that liq. nitrogen is so easy to get at (you're in the 
phys dept, so you know what i mean).

If it's so well known, how come we never hear about it from the lock 
manufacturers?

Good point abou the torch, though! But, I guess that would take longer than 
the freezing method (i've seen it done in a matter of seconds, 
but not on a lock).
