You usually have to choose between passing grades and being a mischief maker in grade school. But with this brilliant Lego contraption created by NXTLOG member hknssn13, you can be both. It automatically grabs a sheet of paper from a stack, folds it into a paper airplane, and then launches it towards your target.

Built with five servos, ten motors, sensors galore, and a pair of Lego Mindstorms NXT bricks controlling the whole assembly line, the engineering side of this project isn't for the faint of heart. And yes, as far as airplanes go the final product doesn't quite represent the cutting edge paper aircraft design. But they fly, and that's more than can be said for the half-billion dollar F-22.
