Joshua's Catapult

Hooray!  Joshua fixed the kinks in his catapult with great success!  At first he was trying to load ammunition into a yogurt container attached to the end of the arm.  Then he hit on this idea, which is a rope tied to a potato and looped (loosely) around the end of the arm.  He tried launching water balloons too, but they kept bursting before they were launched!
