Tcar, out of interest, pure water can be cooler that 32F/0C and remain liquid. It's called "Stoke's Theorum". Basically when you cool water it can "dip" below 32F/0C in a kind of "spike"... not for very long mind you

Thanks, I'd vaguely heard something like that...but couldn't remember any details.

You can make solutions out of many chemicals, not just NaCl (table salt).

Solutions don't just lower the freezing point, they also raise the boiling point. Antifreeze is a solution (ethylene glycol and water). Salt doesn't work because it destroys the metal, but some early manufacturers (early 1900's) used sugar water in the cooling system.

I'm still waiting for them to light farts. Never had the nerve to try it myself. Probably best left to professionals.

It definitely works, I've done it several times.

A trick I heard about used during WWII-- they would put their beers in a 55 gallon drum full of aviation gasoline, and put an air line at the bottom. The bubbles from the line caused the gas to evaporate, cooling the beers.
