An Indonesian man has created a cool little toy car which is driven by a rubber band powered propeller. In the same way an airplane flies through the skies, this car can drive very fast on the ground, using these aerodynamic principals. The design, which is currently available on Thingiverse can travel up to 4 meters per wind of the propeller, and at the same time can go super fast (see video and more details at http://3dprint.com/84539/rubber-band-powered-car-3d/).
