How It Works
A catapult works like a lever, which is a simple machine. When you push down on one end of the lever and then let go, it changes the direction of the force and pushes the marshmallow in the opposite direction. Levers are used all around us. For example, a seesaw is a lever and so is a pair of scissors!
