Use half of an Easter Egg instead of a bottlecap. Much easier

i just tightened the stick i put in the string and it shoots even further.
A helpful tip : instead of putting a hole through the bottle cap to attach it, just tape it ( it is easier and works just as good).

I Made it!!!!!!! It came out awesome. I did one modification though; I made mine with popsicle sticks. I had to apply masking tape to the corners to strengthen it. A helpful tip: put a small piece of wood of popsicle stick (or anything small) and use that to twirl between the string, then tape or glue on your catapult arm(a pencil or popsicle stick).
