Knex Handheld / Portable Cannon

This handheld cannon is very easy on the pieces and still has a lot of power. It can shoot up to twenty-five feet, which is pretty good for a cannon this size. It even has a handle on the bottom so you can hold it.
The way to building this cannon is pretty self-explanatory, and it took me about 15 minutes max to build it.

I highly recommend it, and it’s pretty good for battle, too.

Supplies

It uses a small amount of pieces, and only one rubber band!
