I need to make a catapult that shoots a 5 gram weight 3 meters. Preferably made out of wood. It doesn't need a trigger. Any help please?

cut out 2 bits of wood as right angle triangles bigger better a rectangle piece of wood to go on the longer straight side on the two right angles get a elastic band a very big one put it through the right angle triangles at the top angle and stick like a tea spoon plastic spoon or anything you want to use that throws it in between the band and twist it round as many times as possible then pull it back and let go you can put a square bit of wood where the front is bu don't have to
