how to build a kids catapult


How To Build A Catapult


A catapult was a medieval rocket launcher it was used to hurl stones rocks and even tar covered rocks which had been set alight,they were designed for maximum damage to property and people.

the catapult I am showing you here won't be as dangerous, but it will fire a ping-pong ball about 30 meters.


1) 1 small block of wood approx 6 inches long 2 inches wide and 1 inch deep.

2) 1 springed clothes pin.

3) 1 cube of wood 1inch x 1inch

4) 1 ice lolly stick (popsicle)

5) 1 cap from a plastic bottle.

6) wood glue

Take the 6inch block and lay it on a flat surface

Then glue the clothes pin to it centred lenghtwise (see pic)

When the glue has set glue the 1 inch cube to the open end of the clothes pin (see pic)

Then glue the popsicle stick to the cube as in the pic

Next glue the bottle lid to the popsicle stick leaving enough space to push it down to fire your catapult.

And there you have it a catapult to fire at your toys.

I hope you have fun with your new toy .....jimmy

I reckon this must be one of those 'weapons of mass destruction' Bush & Blair were hoping for.

Pity they missed this one - would have given them something to crow about. Tom.

lala 9 years ago

this is a really cool catapult! I would use it, but i have to make one so its powered with a rubber band. O well.....It will help me with my science project tho. It will give me some ideas at least!!!!! Seee Yaaaa aroundddd!!!!!!!!!!!!

lala 9 years ago

this catapolt would be PERFECTO if i didn't have to use a rubber band!

If i didn't, i would totally use urs!!! not to be a copy cat or any thing.....LOL

Both my kids are involved in a science week and are having a ping pong ball catapulting comp this week. Was looking at doing something based around a mousetrap but this was so much quicker, easier and it worked, plus there's less chance of a trip to casulty with severed fingers!!

Made one or two little design alterations, used an egg box and cut the ball holder out. Plus we didn't have any wooden pegs but used plastic instead and drilled two little holes one side and screwed the peg to the base.

terifo 7 years ago

Thanks for such an easy plan for a catapult!! Someone posted using 5 clothespins to make it go further, but where would you put them?? My son's teacher is having them launch golf balls. Would extending the launch arm make it go further?? (longer lever?)

Thanks again!! We just finished making balloon powered trash cars and it was frustrating for my son with Aspergers. Hopefully this will be easier!!!

Madeline, Lisa, and Wendy 7 years ago

Thank you very much for this design! My friends and I needed a simple design for a class project. This makes it so much easier. I will let you know if we win :D

hey im doing a physics project and this is like the most simple design i have seen yet..but will it be able to launch a hackey sack 15 feet?

Andrewtheballer 7 years ago

I need to make a medieval catapult for social studies, can this launch a big marshmellow at least 7 feet.

Andrewtheballer 7 years ago

It Works!!! thank you for the idea all though I changed the catapult. I realized that the clothes pin doesn't have very much force to it, so i replaced it with a "Chip Clip." It launched a marshmellow almost 9 feet and is really fun to bug my dogs with!
