Instructables
This cannon is moderately powerful but fun. DO NOT, UNDER ANY CIRCUMSTANCES HOLD IT. DO NOT POINT AT A PERSON OR ANIMAL. TREAT IT LIKE A REAL GUN. Please, be careful. If you do choose to make one, I take no accountability for anything you may do with it. It is not a toy. If anyone is hurt, that's your fault. This is purely  educational. DO NOT TRY THIS AT HOME. I will add pictures soon.

Step 1: Materials

Pyrodex
Paper index card
Ducktape
Fuse
toilet paper
Bamboo skewer
Drill
BBQ Lighter

Step 2: Making

Roll the index card into a fuse around the barrel of the lighter. Wrap with 1/4 inch of ducktape all the way up the barrel. Cap 1 end with 1/4 inch of ducktape strips and make sure it is tight and firm as well as thick. Drill a hole in the tube at this end. That's your gun.


Step 3: Shooting

Pack with about 1/3 of a teaspoon of gunpowder. Ram in tissue on top gently.  Put fuse in hole at back. Make sure it is at least a 7 second fuse. Light when pointed in a safe direction and run for some kind of cover. Preform while wearing safety goggles. Do not stand directly in front of or behind when it is loaded. 

When I tried it, the kickback destroyed the box it was placed in, but this is because I put in some BB's (A major DO NOT.). A copper pipe properly capped at one end works better, but that's your choice.

NOW, PLEASE BE CAREFUL. DO NOT, UNDER ANY CIRCUMSTANCES HOLD IT. DO NOT POINT AT A PERSON OR ANIMAL. TREAT IT LIKE A REAL GUN. Please, be careful. If you do choose to make one, I take no accountability for anything you may do with it. It is not a toy. If anyone is hurt, that's your fault. This is purely  educational. DO NOT TRY THIS AT HOME

Wow what a way to blow yourself up. We use to do stuff like this to until we overpacked a item and a piece of copper wizzed by our heads. Stuff like this doesn't need to be on instructables. Kids look at this and think its a good idea since in movies and games they get a reset.

I understand your concern, but it has less power than an airsoft gun and the explosive potential of a small firecracker, as well as a VERY STRONG BODY. I have fired one more than ten times in a row without mishap. The only real risk is the gunpowder itself, and if you own some, than you know how dangerous it is and will automatically respect it.
