I may or may not have any idea what im talking about, but i would just use a regular pneumatic gun that you would shoot spuds out of. and just cram the paper down in their.

If your going to disregard the previous opinions, just remember you arent making a flak cannon or trying to put paper into low orbit, just amuse some people.

Eh no fancy stuff, a crappy valve, not some sci-fi artillery piece that can launch a car 8 miles or something...I really don't know what im talking about when it comes to pneumatic, i generally favor combustions cause the BANG really amuses people. ( and it makes the perfect launcher for skeet shooting )

Well, to me, I am using a regular gun :P . The barrel doesn't need to be 10 feet long, it just needs to look good. And, basically, I am just cramming paper into a spud gun. I just wanted it to be louder.

On a somewhat unrelated note, does anybody know good ways of cutting and working with styrofoam? And a good way of drilling through ~4 feet of styrofoam for a 4" PVC barrel? I was thinking of a hole saw with a piece of threaded rod.

I'm guessing that the 3" barrel was louder because it has a lower volume, thus the air leaves at a higher pressure than with the 4" barrel.

You could probably just use epoxy to attach the hole saw to the rod, and then grip the rod with a drill. Might not be too accurate, but from what I know of your project, high tolerances aren't really necessary.
