While active military and being bored a loong time ago we used to use the co2 fire extinguishers to propell nails and bb's. WE eventually used apiece of pipe and some fittings to propell golf balls. We would unscrew the horn on the extinguisher, and put the "barrel" on it, aim it and then just a quick bump down on the extinguishers handle sent a high pressure charge of CO2 into the barrel and out went the golf ball. On a decent charge it was able to drive nails through 1/2 inch plywood, and when we shot gold balls up against a brick wall actually split some covers on the golf balls......

Since I suck at goll and most other sports it got me to thinking that I may be able to launch these things in some other way than whacking them with a 3 wood (which for some reason I have at least 4 of). So, the question is.. how should I craft a machine to fling these things in a rapid fire fashion very fast and very far? Compressed air might work, spinning wheels a la tennis ball practice machine? gunpowder is not even an option (too loud). Any better Ideas?
