Wine 'legs' and minibot motors (video)

(American Chemical Society) As any wine enthusiast knows, the 'legs' that run down a glass after a gentle swirl of vino can yield clues about alcohol content. Interestingly, the physical phenomenon that helps create these legs can be harnessed to propel tiny motors to carry out tasks on the surface of water. Scientists demonstrate the motors in a report in ACS' journal Langmuir.
