Science Friction (Curling)


Curling has been in the Winter Olympics for four years 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 Vancouver, 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.
