Whammo
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 competitive ta ...

Jaws (film)
''Jaws'' is a 1975 American thriller film directed by Steven Spielberg, based on the 1974 novel by Peter Benchley. It stars Roy Scheider as police chief Martin Brody, who, with the help of a marine biologist ( Richard Dreyfuss) and a professional shark hunter ( Robert Shaw), hunts a man-eating great white shark that attacks beachgoers at a summer resort town. Murray Hamilton plays the mayor, and Lorraine Gary portrays Brody's wife. The screenplay is credited to Benchley, who wrote the first drafts, and actor-writer Carl Gottlieb, who rewrote the script during principal photography. Shot mostly on location on Martha's Vineyard in Massachusetts, ''Jaws'' was the first major motion picture to be shot on the ocean, and consequently had a troubled production with issues such as going over budget and past schedule. As the art department's mechanical sharks often malfunctioned, Spielberg decided mostly to suggest the shark's presence, employing an ominous and minimalist theme cre ...

Limbo Dance
Limbo is a popular 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 Trinidad. 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. Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bomb Shelter
A bomb shelter is a structure designed to provide protection against the effects of a bomb. Types of shelter Different kinds of bomb shelters are configured to protect against different kinds of attack and strengths of hostile explosives. Air raid shelter An air raid shelter is a structure built to protect against bomber planes dropping bombs over a large area. These were commonly seen during World War II, such as the "Anderson shelters" of the United Kingdom. Fallout shelter A fallout shelter is a shelter designed specifically for a nuclear war, with thick walls made from materials intended to block the radiation from fallout resulting from a nuclear explosion. Many such shelters were constructed as civil defense measures during the Cold War. A blast shelter protects against more conventional bomb blasts. Its main purpose is to protect from shock waves and overpressure and also from earthquake. Bunker While these forms of bomb shelters are equally amenable to ci ...

Super Bowl
The Super Bowl is the annual final playoff game of the National Football League (NFL) to determine the league champion. It has served as the final game of every NFL season since 1966, replacing the NFL Championship Game. Since 2022, the game is played on the second Sunday in February. Prior Super Bowls were played on Sundays in early to mid-January from 1967 to 1978, late January from 1979 to 2003, and the first Sunday of February from 2004 to 2021. Winning teams are awarded the Vince Lombardi Trophy, named for the coach who won the first two Super Bowls. Due to the NFL restricting use of its "Super Bowl" trademark, it is frequently referred to as the "big game" or other generic terms by non-sponsoring corporations. The day the game is played is often referred to as "Super Bowl Sunday" or simply "Super Sunday". The game was created as part of a 1966 merger agreement between the NFL and the competing American Football League (AFL) to have their best teams compete for a champi ...

Coefficient Of Restitution
The coefficient of restitution (COR, also denoted by ''e''), is the ratio of the final to initial relative speed between two objects after they collide. It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision. A perfectly inelastic collision has a coefficient of 0, but a 0 value does not have to be perfectly inelastic. It is measured in the Leeb rebound hardness test, expressed as 1000 times the COR, but it is only a valid COR for the test, not as a universal COR for the material being tested. The value is almost always less than 1 due to initial translational kinetic energy being lost to rotational kinetic energy, plastic deformation, and heat. It can be more than 1 if there is an energy gain during the collision from a chemical reaction, a reduction in rotational energy, or another internal energy decrease that contributes to the post-collision velocity. \text (e) = \frac The mathematics were developed by Sir Isaac Newton in 1687. It is also known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polybutadiene
Polybutadiene utadiene rubber BRis a synthetic rubber. Polybutadiene rubber is a polymer formed from the polymerization of the monomer 1,3-butadiene. Polybutadiene has a high resistance to wear and is used especially in the manufacture of tires, which consumes about 70% of the production. Another 25% is used as an additive to improve the toughness (impact resistance) of plastics such as polystyrene and acrylonitrile butadiene styrene (ABS). Polybutadiene rubber accounted for about a quarter of total global consumption of synthetic rubbers in 2012. It is also used to manufacture golf balls, various elastic objects and to coat or encapsulate electronic assemblies, offering high electrical resistivity. The IUPAC refers to polybutadiene as poly (buta-1,3-diene). Buna rubber is a term used to describe an early generation of synthetic polybutadiene rubber produced in Germany by Bayer using sodium as a catalyst.

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 business."

Marlex
Marlex is a trademarked name for 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. 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 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 abnormally allows abdominal contents to slip into a narrow tube called the inguinal canal in the groin region.
