National Science Foundation: Science of the Winter Olympics: Science Friction

Curling has been in the Winter Olympics for a while now, but it still seems a little strange to most of us. John Shuster, the captain - or "skip" - of the U.S. Curling Team in the Vancouver Winter Olympics, explains this unusual sport, and NSF-funded scientists Sam Colbeck, a retired scientist from the U.S. Army Cold Regions Lab, and physicist George Tuthill of Plymouth State University explain the friction that makes it all work.
