Aw, do want!

What the hell?! damn that's amazingly powerful D:

Damn, imagine the amount of damage a life size cannon will do..

holy crap I'm surprised you guys are amazed by this.

I guess I was lucky enough growing up to know a gunsmith. Its not hard to make guns and bombs and such. The physics are rather simple.

^ any chance you can tell your gunsmith to make me one of em mini cannons then :)

I'm not sure what the laws are like but if you have something that can fire a projectile over a certain velocity its Illegal.

The way any projectile works is, as long as your backing is stronger then the projectile, your charge will 'shoot' the lighter smaller material.

another interesting thing is if you take a stick of dynamite, you put some thick puddy or cement on one side of it, you can direct the blast. Pipe bombs and IED are actually simple to make.

that being said, I'm not going to go into detail on an internet forum, thats just stupid. lol.
