Explore physics and math while launching ping pong balls, with this catapult designed for precision!

Ideal for grades 4+

"The catapult kit was excellent. It shoots ping-pong balls repeatably, with the goal of creating histograms of the results. Thanks so much for making this project a success!"




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!

Each kit contains: 

1   Catapult with locking pin
1 Clamp for attaching catapult to table
1 Ping pong ball
1 Light plastic ball with holes
3 Rubber band, 3" x 1/8"


Instructions for this kit are available online, see Additional Information for links to the instructions and more.

Good Catapult Science Fair for Middle School
This was a quick all-inclusive purchase for the materials for a fun and pretty easy science fair project for my son in 7th grade. His science teacher loves it, since it is a math related project that she will send him to the regional science fair with. The materials seem to be of good quality and it was shipped and received quickly and safely.
