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

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

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

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

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.

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 ...
