Introduction: Bean Air Cannon
I made a cannon out of a bean can, here are the steps: #1=find a can and cut out both sides. Next you drill a hole in the bottom cap of the can(about the size of a penny, nickle). Next you take a plastic bag and get it as tight as you can. Then tape it to the can to keep it tight. Now you tape the rest of it (the edge of the can with more duck tape) to keep the bag on. Now you use scissors to cut the bag of. Finally you put duck tape over the bag so it won't rip. Flick the end and this can can blow out a lighter at two meters if you aim right. If you want to make a scope you need to duck tape a small magnifying glass to the front. It will make images upside down but it will work.
