Or a really big CO2 cartridge. An upside down can of air like used
for
dusting out computers held upside down will squirt liquid CO2 at
around -100
F. If you try this wear a very thick and well padded glove.

Liquid CO2? Are you sure that those computer dusting cartridges arent
using some sort of flourocarbons?

Yep, chlorofluorocarbons are banned.

You can still buy Halon fire extinguishers. The manufacture of the halogen
compounds is now banned but existing stores may still be sold.
