Single-molecule 'electric car' taken for test drive

Scientists have shown off what can be described as the world's smallest electric car - made of a single, carefully designed molecule.

The molecule has four branches that act as wheels, rotating when a tiny metal tip applied a small current to them.

With 10 electric bursts, the car was made to move six billionths of a metre.
