Here it is the best of the best life size (or almost life size) war cannon. Yes I know there are lots of knex cannons on Instructables but this one is different from the rest. It looks like a cannon. It will shoot 60 - 70 feet with 2 rubber bands ,and will shoot though 4 pieces of paper. This does use ALOT of parts so I took the time to take a part count so you don't waste your time. It uses a more simple trigger Then IAC cannon but it(kinda) uses the same mech.
