A catapult is a type of lever that uses a fulcrum to launch a projectile. There are many types of levers but in order to launch something, the catapult needs a fulcrum. A fulcrum is a pivot point or the point on which the lever turns to lift something. In this instance, the more force applied to the fulcrum, the further an object will travel.

Step 1: Combine
Use the rubber bands to tightly bind 2 popsicle sticks at one end.
Step 2: Wedge
Place a wedge material as close as you can in between popsicle sticks to the rubber band end. Your wedge material can be a piece of paper, a piece of plastic, or a piece of rubber. Experiment with different materials!
