For the love of god, bash that against the sidewalk and throw that out now so no one can ever use it again!

I don't want to sound mean or anything, on the contrary. That pipe is thinwall PVC and is the type of pipe used by the people who you hear stories about. You know, Headline: "Jonny's Potato Cannon Blows up and Kills Dog!" or the classic "My uncle had a potato gun and it blew up and shot pipe all over and those things are really really dangerous and they should be illegal!"

Please, for your sake and mine, don't use this gun. I don't want these guns banned and more importantly, I don't want you hurt.

Otherwise, cool!

Yeah you probablyt shouldn't use it since its thinwall but whatever. What is the hole in the middle for? I'm assuming you just put the projectile right in there but then what do you use to cover it up?

It would blow the hoppers lid off upon firing.
EEK thinwall cheepo pvc.
Fill the gun with propane andrig remote ignition and blow that thing up in a steel box.
