That spudgun link brought tears to my eyes. Thing is I'm at work so I have been painfully trying to surpress laughterfor the Last 20 minutes.

Would it be possible to build one of those using scaffolding pipe as the barrel? I guess it would be heavy, but you wouldn't have to worry about muzzle explosions.

Another link for spudguns...

Air Spud potato cannon

Just a thought relating this to the orignal post. You could build a gravity railgun. Have a point of extreme gravity attraction at the tip of the barrel, the potato/nail/object will accelerate towards the point, then right as it gets to it, you turn the gravity point off and let inertia do its trick.

Of course, having the same weapons as everyone else but "gravity powered" might be boring
