Indeed the chemistry and/or physics departments often have a fairly large 
dewar around.  If you talk to the right people (the "lab manager") and give 
them a good story about how you're going to experiment with Tesla coils, 
you could walk away with several liters for free.  Local manufacturing 
plants use LN2 to cool bushings and other such interference-fit items prior 
o installation.  (Watching an 8" bushing get stuck on instll once was 
interesting....  Lots of LN2 and big torches :o )

A styrofoam cooler may work for stationary storage, I would strongly 
discourage anyone from using it as a mobile storage....
