i have found that a gas that is used to power airsoft guns works quite well for launching spuds...its simply called green gas and you can find it at a piant ball or airsoft shop for around 15$

i belive it works better than anything else i have found, and i thought i should let every one know about it

Sorry to steal your thunder, but green gas is basically just propane - and we've been using propane to fuel cannons for years and years now.
Does that thing kinda look like a big cat to you?

Yep- ragnarok is correct. "green gas" is simply a term for canned propane that was used in slightly older pellet and bb guns, and sometimes in pneumatic air soft weapons rather than CO2, HPA, freon's etc..

Yep- gasses such as propane, butane etc have an unpleasant and irregular scent added to them to alert people to possible leakages. While it may stink, it's a good method of checking if there are leaks or rich mixtures.

The technical term is "odorfactant". From the Latin meaning "smells like someone had burritos for lunch".
