Step 5Almost ready.
You have put some tape around the lip of the container for a better seal. Push it down to the last 12 inches of your cannon with a broom stick. Put your candy in. and you're in business.
The finer points of potato guns are widely available on the internet. This one is probably pretty crude. The point of this instructable is again, about delivering candy without dangerous projectiles. A giant slingshot, or pneumatic cannon might be better alternatives, but I like the explosion, and so do the neighborhood kids. Their parents not so much.
- leaves or toilet paper or confetti can enhance the effect.
- Rice cakes are another safe item to add to your load
- you fill it up with water if you like, or paint for that matter, but I find even the moisture from the combustion makes for a lot of mis-fires.
- to make retrieval of the container easier, i tried attaching a tether and it tore right off. good luck with that!
-for a good shot keep in mind, the projectile's friction holding it in the barrel is crucial. the longer the pressure can build up, the better the force of the cannon. a loose fitting container may not even leave the barrel, but still move the candy out.
