how to build a kids catapult

CATAPULT

How To Build A 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.

Materials

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

    Hmmmmmmm, Interesting! D&T at a Hampshire school have built a spring loaded catapult just 1.5 mtrs tall. It fires a cricket ball 215mtrs. Donating it to the sports dept for catching practice. Year 7 will naever be the same.

    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!

    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!!!
