Dude, is that seriously a coil on the side of that? You have to post the instructions later!

Yes, that's an automotive ignition coil, and yes, it's got a hell of a kick... I will post a tutorial soon. :-)

Oowwww.

I was thinking the same thing as Toasty; car parts as part of a weapon. Fucking awesome. 5 stars for the humorous credits, the brutality of the potato cannon, and the editing.

That was one sheet of 3/4 ply. I have gone through 2 sheets. I use about a 3 second spray of Aquanet. :-D

The ignition system really makes a difference. I have three spark gaps that ignite the fuel at three points simultaneously, spread the length of the chamber. When you ignite the fuel more rapidly like that, it has mucho more punch.

I'll be making an article on the gun soon. I actually have to rebuild it before I can use it again. Wifey 'accidentally' knocked it over and broke the chamber. X-)

Oowwww.
