That’s unfathomable. How is that physically possible? What type of rock is it? What’s the salinity of the water? Can this be considered a superpower? Is this legal? Is there a special grip involved? How long do you have to practice to do this?
The skipper's name is Kurt Steiner, and he made the throw in September 2013 in the Allegheny National Forest in Pennsylvania.
The most consecutive skips of a stone on water is 88 and was achieved by Kurt Steiner (USA). The cast was achieved at Red Bridge, near Kane, Pennsylvania, USA on 6 September 2013.
Kurt, being the previous record holder for this category from 2002-2007, has been practicing for the past few years to improve his skills. He has collected more than 10,000 "quality rocks" and has sorted each according to its type, to prepare for the best possible throw. He looks for stones "that weigh between 3 - 8 ounces... that are very smooth (they don't have to be perfectly round), flat bottoms and are between 1/4 - 5/16th of an inch thick."
