Really? A working mini-cannon made out of paper?
This little cannon is a homemade device that is actually made out of paper!
In the video, the cannon is test fired against an offending tin can, and the results are quite amusing. Please do not try this at home.
Different projectiles are tried and documented on the video, who knows what else would have worked. It amazes us that someone would come up with the idea of a paper cannon, and even more, that it actually works!
