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.
