Introduction: My Knex Catapult
I built some ones catapult that shot marbles but i have made it to shoot knex wheels, i have also added a firing mechanism on it .
I give credit to the original catapult's owner
funniest thing I ever flung with it was a bit of turkey burger at my mum
i will post when i get positive comments
it need's a lot of modification
it's the best i could do with limited suply of knex
