How to Build a Catapult That Shoots 50 Yards

Updated April 17, 2017

Catapults were used to tear down castle walls in the middle ages. Create your own mini-version of a catapult and shoot things far into the distance. Make your own catapult with a 50-yard range and build your own homemade "medieval rocket launcher," although not as dangerous. Make one from bits and bobs you find around the house. Once you build a catapult that shoots 50 yards, pick up a ping pong ball and aim, set, fire!

Take the 6-inch wooden block and lie it on a flat surface.

Glue a clothes pin to the wooden block. Center it lengthwise.

Attach the bottle lid to the end of the Popsicle stick. Leave enough space to push it down before firing your catapult.

Place a ping pong ball on top of your bottle lid and test your catapult. Measure the distance it fires. It should reach up to 50 yards but, if not, find a large clothes peg and a separate spring to attach underneath to create more elasticity.

Paint your catapult.

Tip

Use different-sized springs to create a longer catapult distance.
