Personally, I use butane. It doesn't leave residue and Is easy to induce using an old blowtorch without an ignition flint. Just open up the valve for 15-20 seconds and seal the chamber. Add the projectile and pressurize the whole unit using a broomstick to push the projectile into the barrel and pressurize the chamber. Finally, aim and fire.

* Note: Never use a propellant that leaves residue, so for the love of god, don't use hairspray .

Depends on what size your cannon is, and how much you are willing to spend per shot. My main cannon is pneumatic so it is virtually free. but my smaller cannon is run of of bug spray, (its made of a ballpoint pen and a chapstick container). Use this website as a reference http://www.aaroncake.net/spuds/boom.asp, they have a list of pros and cons of each Propellant.  http://www.spudfiles.com/ also gives you good information on potato cannons. The three most used propellants are hairspray, propane and deodorants. Propane is expensive and hard to use but burns the best, the other two are good but can gum up your chamber. best of luck to you.
