Introduction: Small and Easy But Powerful Catapult

Picture of Small and Easy But Powerful Catapult

A catapult made out of a paper binder and rubberband. Great for launching things during class. I got this off of Youtube.

Step 1: Make It

Wrap rubberband around the binder.

Step 2: How to Shoot

Hold onto one side of binder. Pull back the other. Put ammo on the one side being pulled back. Let go of one that is pulled back

The only trouble is finding something small.....

Gunbuilder (author)Iman4462009-03-10

the best ammo are small marbles, they fit perfectly in the clip i used XP

You could just use the binder clip but it wouldn't be as powerful.

Mantyke (author)2009-01-29

Nice, it owns!!

h3llo41 (author)2008-09-21

it'll be much stronger if you wrap the rubber band tightly around the silver part of clipper

Nice things to shoot your friends in a boring class at school!

lobo_pal (author)2008-08-25

If you can't figure it out, than you're dumb. You just pull down on one of the handles with a piece of paper or something, and than release. I would suggest adding something to lengthen the handles, or increase the overall size of the catapult though.

The video doesn't work can you please post another link to it.

glycerinate (author)2007-12-13

pacmanjones (author)2007-11-18

thats sweet

Why Does It Hurt (author)2007-07-27

what do you do?

I'm confused


Well if you cant figure this out what's your problem??

Saddam and Osama (author)2007-06-20

I've tried different modifications, and here are some of them: 1) Attach a spoon (preferably metal, plastic might break) on one side and under all the rubber bands. (Also attach rubberbands from the handles to the spoon) 2) To prevent the rubberbands from falling from the bottom, you can tape the sides of the clip or attach rubberbands around the sides.

Add some images

This is so simple and ingenious. I can fire over one-story houses! So small too ... so discreet ...
