Helped my student make this catapult for a high school physics project.  Used 2" scrap lumber, screws, 2 cup hooks, and a short bungee cord. Made a projectile seat out of card stock and hot glued it on. Also copied a protractor and taped it to the side for calibration. Throws a small bean bag about 10 meters (32.8 ft) at full force.

If you thought being flicked by a rubber band hurt, imagine being shot at by the Rubber Band Rambo Gatling gun that pings out 672 elastic stingers in just 48 seconds - that's 14 shots per second fired up to 26 feet.  Ukranian student and inventor Alexander Shpetniy created the gun with a $5,000 Kickstarter goal. He's now about to hit $100,000.
