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

Iman446 says: Jan 22, 2009. 4:50 AM

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

Gunbuilder in reply to Iman446Mar 10, 2009. 6:17 AM

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

Mantyke in reply to Iman446Jan 29, 2009. 12:56 PM

RUBBER!!! :D

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

Mantyke says: Jan 29, 2009. 12:56 PM

Nice, it owns!!

h3llo41 says: Sep 21, 2008. 11:53 AM

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

How does it work?

maharg20 in reply to mrgboardSep 10, 2008. 5:53 PM

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

lobo_pal says: Aug 25, 2008. 5:28 PM

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.

Nevermind

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

Saddam and Osama says: Jun 20, 2007. 9:20 AM

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.

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