Researchers at the Japan Institute of Technology have a killer demo for their controlled quantum levitation technology: they outfitted little slot-car-style RC cars with liquid nitrogen tanks and sent them whizzing around a track modelled on the classic video game Wipe Out.
Update: Many commenters believe that this is faked. They can tell by the pixels apparently. And the physics. It's still awful fun to watch.
