Here it is: my cannon. It shoots large missiles, and shoots them hard. It is powered by 48 rubber bands, tied together into 8 strings of 6. It is 2 feet wide (on the bow) and 5 feet long. It has an average range of about 100 feet shot from the resting position. It uses a ton of pieces, I know, though I might work on a smaller version later. If you do build my cannon, please know that I am in no way responsible for any damage done with it.
I have made a few other versions of this gun. Check them out!MiniNanoMicroHandheld
