The smallest car race in the world (w/video)

(Nanowerk News) The first-ever international race of molecule-cars (Nanocar Race) will take place at the CEMES laboratory in Toulouse this fall.
Five teams are fine-tuning their cars—each made up of around a hundred atoms and measuring a few nanometers in length. They will be propelled by an electric current on a gold atom "race track."
We take you behind the scenes to see how these researcher-racers are preparing for the NanoCar Race:
