Buy a section of metal water pipe 1/2 by 6 inches long, threaded on both ends. Buy two metal caps to fit. These are standard items in hardware stores. Drill a 1/16th hole in the center of the pipe. This is easy with a good drill bit. Hanson is a good brand to use. Screw a metal cap tightly on one end. Fill the pipe to within 1/2 inch of the top with black powder. Do not pack the powder. Don't even tap the bottom of the pipe to make it settle. You want the powder loose. For maximum explosive effect, you need dry, fine powder sitting loose in a very rigid container.

I do believe you forgot the fuse... Electrical ignition elements, such as the ones used to launch model rockets should work just fine. -- Lucky Green <mailto:shamrock@netcom.com> PGP encrypted mail preferred.
