DO NOT USE ANYTHING in ANY of these DEVICES EXCEPT Marshmallows. IF YOU LAUNCH anything else with these catapults you could injure your eye or someone else's eye or other parts of someone's body. If you do launch marshmallows be certain they are the large ones not the small ones because a small one could get stuck in a child's throat.

Scouts and Schools enjoy a game I teach called catapult. I bring a catapult with me. Marshmallows are hurled at a target, sometimes the target is me, and we determine who would have made the best catapultists. However, some groups make their own catapults before I come and they determine who has made the best catapult by firing marshmallows at each other's open mouths.
Here are some other examples of catapults you can build:
