With his latest project, master slingshot builder Joerg Sprave has taken a dangerous classroom weapon -- the rubber band-launched, sharpened pencil -- and turned it deadly.

His "Nerd Revenge 2000" is a pump-action slingshot that can empty a 10-pencil magazine in under five seconds, firing pencils at a range of around 15 feet.

Once he adds field tips from actual arrows to the pencils, they pack even more power, traveling at around 97 MPH.

Sprave has declared this his most fun slingshot ever, which is high praise coming from the guy who invented a slingshot that shoots saw blades.
