With this rubber-band powered catapult, you'll send ping pong balls flying through the air to learn about physics and math! This ping pong ball launcher provides a memorable way for students to learn about projectile motion. Providing hours of fun, this simple machine is an educational and engaging STEM activity for curious and creative minds!

Designed by professors at the University of Pennsylvania, this ping pong ball 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 and catapult ammo (like ping pong balls) 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 ping pong catapult. Use one of the Science Buddies project ideas for your physics project, or use them as inspiration to create your own unique DIY physics or math exploration!

Instructions for this ping pong catapult kit are available online. See below for links to the instructions, frequently asked questions, and more.
