Catapult

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.

• 2 popsicle sticks
• 2 rubber bands
• Wedge material (paper, cork, plastic, etc)
• Holder (bottle cap, cardboard, aluminum foil, etc.)

Use the rubber bands to tightly bind 2 popsicle sticks at one end.

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!

Create and attach your holder to the non- rubber band end. Your holder can be made a bottle cap, cardboard, or plastic.

Place a projectile in your holder, press down and release!
