Frisbees
A frisbee (pronounced ), also called a flying disc or simply a disc, is a gliding toy or sporting item generally made of injection-molded plastic and roughly in diameter with a pronounced lip. It is used recreationally and competitively for throwing and catching, as in flying disc games. The shape of the disc is an airfoil in cross-section which allows it to fly by reducing the drag and increasing lift as it moves through the air, compared to a flat plate. Spinning the disc imparts a stabilizing gyroscopic force, allowing it to be both aimed with accuracy and thrown for distance. A wide range is available of flying disc variants. Those for disc golf are usually smaller but denser compared to ultimate frisbee, and tailored for particular flight profiles to increase or decrease stability and distance. The longest recorded disc throw is by David Wiggins Jr. with a distance of . Disc dog sports use relatively slow-flying discs made of more pliable material to better resist a do ...

Wham-O
Wham-O Inc. is an American toy company based in Carson, California, United States. It is known for creating and marketing many popular toys for nearly 70 years, including the Hula hoop, Frisbee, Slip 'N Slide, Super Ball, Trac-Ball, Silly String, Hacky sack, Wham-O Bird Ornithopter and Boogie Board, many of which have become genericized trademarks. Corporate history Richard Knerr (1925–2008) and Arthur "Spud" Melin (1924–2002), two University of Southern California graduates who were friends since their teens, were unhappy with their jobs and decided to start their own business. In 1948 they formed the WHAM-O Manufacturing Company in the Knerr family garage in South Pasadena. Their first product was the Wham-O Slingshot, made of ash wood, which Knerr and Melin promoted by holding demonstrations of their own slingshot skills. The name "Wham-O" was inspired by the sound of the slingshot's shot hitting the target. The powerful slingshot was adopted by clubs for competi ...

Ed Headrick
Edward Early Headrick, known as "Steady" Ed Headrick, (June 28, 1924 – August 12, 2002) was the father of the modern-day frisbee, creator of disc golf, and inventor of the metal cage disc golf targets. Per his request, his ashes were incorporated into discs, which were sold to fund a museum and disc golf center in Columbia County, Georgia. Early life and Wham-O career Headrick was born in South Pasadena, California on June 28, 1924. Before his career in the toy industry, he fought in the army in Europe during WWII and worked several jobs including deep-sea welder and water heater salesman. He was connected with Arthur Melin, who co-owned Wham-O, and in 1964 he worked three months without pay to prove his worth. He then led Wham-O's research and development where he evaluated new toy ideas such as the highly successful Super Ball, which he market-tested at a liquor store before release ensure its appeal with adults. He was tasked with repurposing excess plastic leftover fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultimate Frisbee
Ultimate frisbee (officially simply called ultimate) is a non-contact team sport played with a disc flung by hand. Ultimate was developed in 1968 by Joel Silver, Buzzy Hellring, and Jonny Hines in Maplewood, New Jersey. Although ultimate resembles many traditional sports in its athletic requirements, it is unlike most sports due to its focus on self-officiating, even at the highest levels of competition. The term "frisbee" is a registered trademark of the Wham-O toy company, and thus the sport is not formally called "ultimate frisbee", though this name is still in common casual use (and the trademark was licensed to the Ultimate Frisbee Association in 2024). Points are scored by passing the disc to a teammate in the opposing end zone. Other basic rules are that players must not take steps while holding the disc, and interceptions, incomplete passes, and passes out of bounds are turnovers. Rain, wind, or occasionally other adversities can make for a testing match with rapid tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guts (flying Disc Game)
Guts or disc guts (sometimes guts Frisbee in reference to the trademarked brand name) is a disc game inspired by dodgeball, involving teams throwing a flying disc (rather than balls) at members of the opposing team. Game play One to five team members stand in a line facing the opposing team across the court, with the two teams lined up parallel to each other. Which team begins play is determined by "flipping the disc", an action similar to a coin toss, but using the disc itself. One member of the team is then selected to start play. That member then raises an arm to indicate readiness to throw, at which point the members of the opposing team freeze in position. The thrower then throws the disc as hard as possible at someone on the opposing team. If the thrower misses the "scoring area" (a demarcated area a bit larger than the space occupied by the opposing team), the receiving team scores a point. If a member of the receiving team catches the disc cleanly, neither team scor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kenneth Arnold UFO Sighting
On June 24, 1947, private pilot Kenneth Arnold claimed that he saw a string of nine, shiny unidentified flying objects flying past Mount Rainier at speeds that he estimated to be at least . This was the first post-World War II sighting in the United States that garnered nationwide news coverage and is credited with being the first of the modern era of UFO sightings, including numerous reported sightings over the next two to three weeks. Arnold's description of the objects also led to the press quickly coining the terms ''flying saucer'' and ''flying disc'' as popular descriptive terms for UFOs. Sighting On June 24, 1947, Arnold was flying from Chehalis, Washington, to Yakima, Washington, in a CallAir A-2 on a business trip. He made a brief detour after learning of a $5,000 reward (equivalent to $ today) for the discovery of a U.S. Marine Corps C-46 Commando, C-46 transport airplane that had crashed near Mount Rainier. The skies were completely clear and there was a mild wind. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Disc Freestyle
Flying disc freestyle, also known as freestyle Frisbee in reference to the trademarked brand name, is a sport and performing art characterized by creative, acrobatic, and athletic maneuvers with a flying disc. Freestyle is performed individually or more commonly in groups, both competitively and recreationally. The Freestyle Players Association (FPA) is the governing body of freestyle, "dedicated to the growth of freestyle disc play as a lifetime recreation and competitive sport. The organization is involved in international tournaments and rankings as well as education grants and promotional activities. Every year, the FPA holds a world championship with divisions in Open Pairs, Mixed Pairs, Open Co-op, and Women's Pairs. Competitive freestyle is usually judged on execution, difficulty, and artistic impression by a panel of players. History By the late 1960s and early 1970s, modern flying discs had become a popular pastime in the United States, developing into various discipli ...

Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest Chord (geometry), chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. The word "diameter" is derived from (), "diameter of a circle", from (), "across, through" and (), "measure". It is often abbreviated \text, \text, d, or \varnothing. Constructions With straightedge and compass, a diameter of a given circle can be constructed as the perpendicular bisector of an arbitrary chord. Drawing two diameters in this way can be used to locate the center of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
