This Week in Science Part 2:

A study on the physics of skipping stones across water found it might be fun to use round rocks sometimes.  Flat rocks will give you more skips.  But heavier, rounder stones are more likely to give you one big “mega-bounce.” The stone is important, but successful skimming is also about good technique. The Guinness World Record for most skips of a skimming stone belongs to Kurt Steiner, who generated an astounding 88 skips in 2013. Steiner prefers thin, smooth, flat-bottomed stones. Guinness currently keeps records for most skips and farthest distance. Maybe it’s time to add a category for highest bounce.
