Stone cuttings (or skimming stones ) is the art of throwing flat stones across the water in such a way that it bounces off the surface, preferably many times over. The purpose of the game is to see how many times a rock can soar before drowning.

Championships and recordings

The North American Skipping Stone Association (NASSA), founded by Coleman-McGhee, in 1989 and based in Driftwood, Texas, supported the four-year world championships from 1989 to 1992 in Wimberley, Texas. The next official NASSA World Championships are expected to be held at Platja d'en Ros beach in CadaquÃÆ'Â © s, Catalonia, Spain.

The world record for the number of jumps Guinness Book of Records was 88 by Kurt "Mountain Man" Steiner, age 48. The cast was reached on September 6, 2013 at Red Bridge in Allegheny National Forest, Pennsylvania. The previous record was 65 skips, by Max Steiner, set at Riverfront Park, Franklin, Pennsylvania. Before him, the record was 51 jumped, set by Russell Byars on July 19, 2007, skipping in the same location. Kurt Steiner also holds the world record between 2002 and 2007. US champion Rock Skipping 2017 at Franklin is Drew Quayle with 40 jumps.

Different rock-hunting championships take place every year in Easdale, Scotland, where distance is measured as opposed to the number of jumps, as is likely to occur outside the US. Since 1997, competitors from around the world have taken part in the World Stone Skimming Championships at a quarry excavated on Easdale Island using Easdale slabs worn at sea with a maximum diameter of 3. "Each participant gets three throws and the stone must bounce/jump at least three times to count.The current world champion is Keisuke Hashimoto from Japan, who is also the national champion of Japan.Holder holders from competitions held in the past year include Nina Luginbuhl (Switzerland) World Women's Champion 2017 and Welsh Open 2018 women champion : Gareth Twamley (Wales) 2017 All England, Barbara Maher (England) All England Women 2017, Alex Lewis (Scotland) 2017 England, Charlotte Greenway 2017 British Woman, Kurt Steiner (USA) 2018 Welsh Open A table holder of WSSC Easdale title follows Paul Crabtree (UK) is the first European champion in 2012 to repeat for 2013 & 2014. Events require users aan natural stone course, except for Wales. The world record for long range skiing mmed using laser-surveyed natural rocks at 121.8 meters (400Ã, ft), at a Guinness-backed event held at Abernant Lake, Llanwrtyd Wells, Powys, Wales on Monday 28 May 2018. The toss created by Dougie Isaacs of Scotland. The first female long-distance recording was also established at the same event - 52.5 m (172Ã, ft) cast by Nina Luginbuhl of Switzerland.

Scientific explanation

Early explanations of stone jump physics were given by Lazzaro Spallanzani in the 18th century.

The stone produces the same force as a flying disc, by pushing water downward as it travels across the water at an angle. Surface tension is very small to do with it. The rock rotation acts to stabilize it against the applied torque backward.

Research conducted by a team led by the French physicist LydÃÆ' Â © ric Bocquet found that an angle of about 20 Â ° between the rock and the water surface was optimal. Bocquet and his colleagues were surprised to find that changes in speed and rotation did not change this fact. Work by Hewitt, Balmforth and McElwaine has shown that if horizontal speeds can be maintained skipping can continue indefinitely. Previous research reported by Bocquet calculated that 38 rebound world records created by Coleman-McGhee, unparalleled for years, requires a speed of 12 m/s (25 mph), with a rotation of 14 revolutions per second.
