You can't out-think a thinking man

[Red Arrow]

Wonder what sort of spud gun we could create with 2" x 20ft. of Sch. 80 pipe?  I bet it would take one heck of an Aqua-Net charge.  I'm thinking you could launch a huge russet from the Holly east refinery to at least the Blue Rose without bowing the barrel.  Rifling would be a nice touch too

You might be able to get some ideas from the punkin chunkin' guys.  I've seen them on Discovery channel or something like that a few times.

I want a trebuchet that can launch a piano!

Might be a little safer to use compressed air rather than AquaNet for the potato chunker.  Control max pressure better.

Rifling?  Hmmm...maybe a groove cutter of some sort?

No, that's the point!  The unpredictability of a flammable and rapidly-expanding charge is the whole idea!

We're gonna need bigger pipe!  And a LOT more AquaNet!!

One thing you need to know - I am ALL about the LOUD noises and BIG flashes of light!!  Love 'em!!!

This is about the right size!  Just take a large commercial water heater, insert fusionable materials to the fill line, the light 'er up!!
And William Shattner, to boot!!
