This 2006 gameshow clip shows contestants running back and forth atop a deep pool of non-Newtonian fluid -- ooblek -- without sinking in. They run, they skip, they hop, and maintain admirable aplomb atop the surface. It gets especially nice when the host stops in his tracks and sinks down into the mucky depths.
Running on a long, deep pool of ooblek
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
