How to build a catapult step by step?
To build a catapult you need wood, 3 pieces 12 inches long, 8 pieces 6 inches long, assorted small screws and nails, several small rubber bands, 2 eye hooks and some glue, 1 four inch square of cardboard and 1 6 in long metal bar. Gather all your materials and then cut the wood into the required pieces, cut them in angles. Drill a hole in the catapult arm about 1/2 inches from one end. . This hole should just be a little bit bigger than the metal bar you are using. Now put a hook about three inches from the other end of the arm. Now make the catapult cup by cutting and folding your 4 inch piece of poster board or cardboard. Then glue it to the end of the catapult arm. Put it right up against the hook. This will close off the hook so you can squeeze the rubber band onto the hook and the cup keeps the hook closed and the band can’t escape. There will be about an inch of wood sticking out past the end of the cup. This is perfect, it gives you something to press down on when firing the cat
