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 ...

Exhibition Shooting
Exhibition shooting or trick shooting is a sport in which a marksman performs various feats of skill, frequently using non-traditional targets. Exhibition shooting tends to stress both speed and accuracy, often with elements of danger added. Famous shooters Annie Oakley With the advent of rifling came accurate firearms, and many exhibition shooters turned to these, forming the beginnings of western exhibition shooting. The most famous exhibition shooter is Annie Oakley, who toured with Buffalo Bill's Wild West show. While she could shoot well with handguns, rifles, and shotguns, Oakley's preferred firearm was a .22 caliber rifle. Standard tricks of Oakley's included: * Cutting a playing card in half with a rifle bullet at long ranges * Shooting cigarettes in half while they were held by volunteers * Shooting a dime tossed in the air, at range of 90 feet * Shooting long strings of targets tossed in the air; in one instance she hit 4472 out of 5000 in a single day.

Limbo Dance
Limbo is a game, based on traditions that originated on the island of Trinidad . The aim is to pass forwards under a low bar without falling or dislodging the bar. The dance originated as an event that took place at wakes in Tobago. It was popularized in the 1950s by dance pioneer Julia Edwards (known as the First Lady of Limbo) and her company which appeared in several films, in particular ''Fire Down Below'' (1957), and toured widely in the Caribbean, Europe, North America, South America, Asia, and Africa in the 1960s and later. Rules A horizontal bar, known as the limbo bar, is supported by two vertical bars. All contestants must attempt to go under the bar with their backs facing toward the floor. When passing under the bar, players must bend backwards. No part of their body is allowed to touch the bar, and no part other than their feet may touch the ground. They must not turn their head or neck to the side. Whoever knocks the bar off or falls is eliminated. After everyo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coefficient Of Restitution
In physics, the coefficient of restitution (COR, also denoted by ''e''), can be thought of as a measure of the elasticity of a collision between two bodies. It is a dimensionless parameter defined as the ratio of the relative velocity of separation after a two-body collision to the relative velocity of approach before collision. In most real-word collisions, the value of ''e'' lies somewhere between 0 and 1, where 1 represents a perfectly elastic collision (in which the objects rebound with no loss of speed but in the opposite directions) and 0 a perfectly inelastic collision (in which the objects do not rebound at all, and end up touching). The basic equation, sometimes known as Newton's restitution equation, was developed by Sir Isaac Newton in 1687.\text (e) = \frac Introduction As a property of paired objects The COR is a property of a ''pair'' of objects in a collision, not a single object. If a given object collides with two different objects, each collision has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polybutadiene
Polybutadiene utadiene rubber, BRis a synthetic rubber. It offers high elasticity, high resistance to wear, good strength even without fillers, and excellent abrasion resistance when filled and vulcanized. "Polybutadiene" is a collective name for homopolymers formed from the polymerization of the monomer 1,3-butadiene. The IUPAC refers to polybutadiene as "poly(buta-1,3-diene)". Historically, an early generation of synthetic polybutadiene rubber produced in Germany by Bayer using sodium as a catalyst was known as "Buna rubber". Polybutadiene is typically crosslinked with sulphur, however, it has also been shown that it can be UV cured when bis-benzophenone additives are incorporated into the formulation. Polybutadiene rubber (BR) accounted for about 28% of total global consumption of synthetic rubbers in 2020, whereas styrene-butadiene rubber (SBR) was by far the most important grade (S-SBR 12%, E-SBR 27% of the entire synthetic rubber market). It is mainly used in the manuf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Frederick Morrison
Walter Frederick Morrison (January 23, 1920 – February 9, 2010) was an American inventor and entrepreneur, who invented the Frisbee. Early life Walter Fredrick "Fred" Morrison was born on January 23, 1920, in Richfield, Utah, the son of Dr. Walter F. Morrison, an optometrist. Career Morrison stated that the original idea for a flying disc toy came to him in 1937, while throwing a popcorn can lid with his girlfriend, Lucile Eleanor "Lu" Nay (1920–1987), whom he later married on April 3, 1939, in Los Angeles, California. The popcorn can lid soon dented which led to the discovery that cake pans flew better and were more common. A year later, Morrison and Lu were offered 25 cents () for a cake pan that they were tossing back and forth on a Santa Monica, California, beach. Morrison detailed, in a 2007 interview, "That got the wheels turning, because you could buy a cake pan for five cents, and if people on the beach were willing to pay a quarter for it, well—there was a busines ...

Marlex
Marlex is a trademarked name for a crystalline polypropylene and high-density polyethylene (HDPE). These plastics were invented by J. Paul Hogan and Robert Banks, two research chemists at the Phillips Petroleum Company in 1951. Interest in the material in the 1950s arose from its high melting point and tensile strength, making it more desirable than the more common form of polyethylene. For example, the medical community in 1958 was eager to use Marlex 50 crystalline polyethylene which softens at . Objects made of Marlex could be sterilized in high-temperature autoclaves without affecting their form. Marlex was used by Wham-O for their Hula Hoops in the 1950s, which helped create a market for this form of plastic. It is now an integral part to a wide variety of products and markets around the world. Additionally, it can be used surgically as a reinforcing mesh in inguinal hernia repair Inguinal hernia surgery is an operation to repair a weakness in the abdominal wall that ab ...

Frisbee 090719
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 dog ...
