Improvements to the Spud Gun Potato Launcher

The 2008 basic PVC spud gun has been improved with a better way to inject a measured amount of propane gas into the combustion chamber for quicker loading and consistent results. Its always fun to launch a few potatoes on the 4th of July. Propane produces a loud, high pitched, boom and a blue color. A shot of hairspray gives a great orange glow and a lower pitched sound, so maybe next year I'll find a way to blend both gases for good spud distance, barrel sound and color.

I've never seen a Fuel Meter done with PVC (or such a low pressure). But it seems to work and that's what counts...
