Things You'll Need
Wooden block, 6-by-2-by-1-inches
Springed clothes pin
Cube of wood
Popsicle stick
Cap from a plastic bottle
Wood glue
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!
Step 1
Take the 6-inch wooden block and lie it on a flat surface.

Step 2
Glue a clothes pin to the wooden block. Center it lengthwise.
Step 3
Attach the bottle lid to the end of the Popsicle stick. Leave enough space to push it down before firing your catapult.
Step 4
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.
Step 5
Paint your catapult.
Tip
Use different-sized springs to create a longer catapult distance.
