Tiniest car... ever!
Ever wanted to cruise down a nanoscopic highway 1/20,000 the width of a human hair? Boy is today ever your lucky day - Read this article about the invention of a nano car! Some scientists at Rice University have developed a 'nano car' with a working engine. When light is shined upon the car 'molecule', there is a particle on the car that begins to turn in one direction. This nano-motor powers the nano car such that it moves off in a straight direction. Pretty wild technology!
