Coat Hanger Catapults - Prototype 3

Well first you need to have a coat hanger, a plastic spoon and two normal rubber bands. Bend the coat hanger so it looks a bit like wings poking upwards. Then put your arm in the middle of both the wings so it's straight. Bend the front part of it into a 'v' shape. Then once you've finished the wire body, get the first rubber band and put it over each arm and stick the spoon through it and twist/wind it up in the direction away from the hook. Once you have turned the rubber band with the spoon in it as far as you want you need to slide the first rubber band down further so that the second rubber band can go about 2 inches. Wind up the second rubber band with your hands but still leave a hole in the middle for the spoon head to poke through.  

Once you've finished that you are ready to fire.  We took our catapult to our school hall and brought jellybeans marshmallows with us to fire.  The first marshamallow went about 6 metres. The jellybeans rolled too much so we had to mark the distances from were they landed. 

The best bit was probably eating the giant jellybeans after we fired them.  Our group only got one jellybean so we had to split it in half and share it.
