With this rubber-band powered catapult you'll send ping pong balls flying through the air to learn about physics and math.

Designed by professors at the University of Pennsylvania, this catapult is ideally suited for scientific exploration. Unlike most wooden catapults, this catapult allows you to easily reproduce a precise launch angle, and measure the amount of potential energy stored before launch. This level of precision provides you with valid data, which can be used to explore all kinds of different scientific questions, while having fun launching projectiles through the air!

To get you started, Science Buddies scientists have created a series of Ping Pong Catapult Projects, providing easy-to-follow online instructions for science fair projects that use the catapult. Use one of the Science Buddies project ideas for your project, or use them as inspiration to create your own unique physics or math exploration!

Instructions for this kit are available online. See below for links to the instructions and more.


Instructions are NOT included with the kit, but are available online from Science Buddies.
