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

Paper index card
toilet paper
Bamboo skewer
BBQ Lighter

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.
<p>But a firecracker can blow your hand off if you hold it in your hand right? That's probably what he means.</p>
<p>To your comment, The1andonlyDaniel, it isn't a good idea to light it, and hold it. You throw them, not hold them. Yes the are dangerous, but if you know how bad they can be, you will respect them far more than if you don't know the damage.</p>
This is really stupid, you are basically making a bomb, if our going to make something like this use a stronger material like steel and *small* powder charges. NO!! smokeless powder, it has a quicker combustion and gas expansion than black powder. If you want to make a bomb use proper safety precautions and don't post it on the internet, unless you want to end up on criminal watch list.<br><br><br>Light things on fire--Stay safe.
