Russell Byars’ managed to get the pebble to travel 250 feet (76 meters). He managed to ‘skim’ a stone across water 51 times, shattering the old world record of 40.

Before declaring him a record holder, Guinness World Records experts analyzed film of Byars’ toss, checking the concentric circles in the water by each skip.

“I actually threw 40 stones that day, but that was the first skip that I threw,” Byars told the Pittsburgh Post-Gazette newspaper, which confirmed the record with Guinness officials.

The old record was set in 2002.
