A pack of mad scientists at Waterloo Labs have managed to do the seemingly impossible: they've created real life Mario Kart.  Marvel at the way their cars spin out and crash when hit with foam Koopa shells.  Gasp as lightning bolts send all the other karts into a crawl.  Stare in awed amazement as mushrooms send karts zipping down the track.

If you watch one YouTube video today, make it this one.
