PROVIDENCE -- Scientific sleuths from Brown University are in California trying to figure out what makes the great jumping frogs of Calaveras County jump so far. "They're spectacular," Manny Azizi, a postdoctoral fellow at Brown, said of the bullfrogs. The contest requires frogs to make three consecutive jumps. Then the total distance is measured. The record is 21 feet.
Mark Twain's famous and fictional tale of a frog-jumping contest started the whole thing. It has now been turned into a real-life, annual event at the Calaveras County Fair and Jumping Frog Jubilee in Angels City, Calif. ( See more at Providence Journal, May 14, 2009 and July 14, 2010)
