Make sure Dad’s never bored with this DIY catapult that doubles as a desk toy! It’s easy to build from common office supplies and fun to use at work or at home.


This is also the perfect gift to make to give to your Dad for Father’s Day! Now when he takes a break to launch a few pom-poms from his DIY catapult, he can think of you. Or better yet, maybe you can launch some pom-poms, too, and turn it into a contest!

How We Did It

Desk Catapult
Gather the materials you need to make your DIY catapult desk toy. 
Desk Catapult

Fold up one arm of the binder clip.

Desk Catapult
Wrap a rubber band around the middle of the binder clip. If it’s loose, keep wrapping it around until it’s tight. I had to wrap mine around three times.
Desk Catapult
Switch the arms, so the one that was up is down and the one that was down is up.
Desk Catapult
Loop a rubber band around the lowered arm and through itself. Pull it tight to attach the band to the arm.
Desk Catapult
Pull the other end of the rubber band through the raised arm. Slot a pencil in between the rubber band loop and the binder clip arm so the rubber band holds the pencil against the arm.
Desk Catapult
Slide the pencil up or down so the end of the pencil is just above the main body of the binder clip. Tape the pencil to the arm of the binder clip.
Desk Catapult
Stick the bottle cap onto the other end of the pencil. We used sticky foam, but you can also use tape or glue. (Make sure the bottle cap is facing forward!)
Desk Catapult

You’re ready for launch! Put a pom-pom in the bottle cap, then hold the binder clip down with one hand and pull the pencil back with the other. Let it go and watch the pom-pom fly from the desk toy!


For extra fun, try seeing how far you can launch your pom-poms, throwing several pom-poms at once, or set out a cup as a target and see if you can land a pom-pom in it!
