Today's style of pinwheels is rooted in East Asia. The design for example is typical of a japanese Origami folding technique for a pinwheel.[ citation needed ]
During the nineteenth century in the United States, any wind-driven toy held aloft by a running child was characterized as a whirligig, including pinwheels. Pinwheels provided many children with numerous minutes of enjoyment and amusement. [1]
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant then the stored (rotational) energy is directly associated with the square of its rotational speed.
A toy or plaything is an object that is used primarily to provide entertainment. Simple examples include toy blocks, board games, and dolls. Toys are often designed for use by children, although many are designed specifically for adults and pets. Toys can provide utilitarian benefits, including physical exercise, cultural awareness, or academic education. Additionally, utilitarian objects, especially those which are no longer needed for their original purpose, can be used as toys. Examples include children building a fort with empty cereal boxes and tissue paper spools, or a toddler playing with a broken TV remote control. The term "toy" can also be used to refer to utilitarian objects purchased for enjoyment rather than need, or for expensive necessities for which a large fraction of the cost represents its ability to provide enjoyment to the owner, such as luxury cars, high-end motorcycles, gaming computers, and flagship smartphones.
Pioneer 6, 7, 8, and 9 were space probes in the Pioneer program, launched between 1965 and 1969. They were a series of solar-orbiting, spin-stabilized, solar cell- and battery-powered satellites designed to obtain measurements on a continuing basis of interplanetary phenomena from widely separated points in space. They were also known as Pioneer A, B, C, and D. The fifth was lost in a launch accident, and therefore did not receive a numerical designation.
A wind vane, weather vane, or weathercock is an instrument used for showing the direction of the wind. It is typically used as an architectural ornament to the highest point of a building. The word vane comes from the Old English word fana, meaning "flag".
The Easy-Bake Oven is a working toy oven introduced in 1963 by Kenner and currently manufactured by Hasbro. The original toy used a pair of ordinary incandescent light bulbs as a heat source; current versions use a true heating element. Kenner sold 500,000 Easy-Bake Ovens in the first year of production. By 1997, more than 16 million Easy-Bake Ovens had been sold.
Pinwheel is an American children's television series that was the first show to air on the then-rebranded Nickelodeon, as well as the first to appear on its Nick Jr. block along reruns until 1990. The show was aimed at preschoolers aged 3–5. It was created by Vivian Horner, an educator who spent her earlier career at the Children's Television Workshop, the company behind PBS's Sesame Street. The show was geared to the "short attention span of preschoolers," with each episode divided into short, self-contained segments including songs, skits, and animations from all over the world.
Die Sendung mit der Maus, often Die Maus, is a German children's television series, popular nationwide for its educational content. The show first aired on 7 March 1971. Originally called Lach- und Sachgeschichten für Fernsehanfänger, it was controversial because West German law prohibited television for children under six years of age. The program was initially condemned by teachers and childcare professionals as bad for children's development, but is now hailed for its ability to convey information to children, having received over 75 awards. On 7 March 1999 the program's Internet site was launched and received 2,400 e-mails and 4 million hits on the first day.
Circuit bending is the creative, chance-based customization of the circuits within electronic devices such as low-voltage, battery-powered guitar effects, children's toys and digital synthesizers to create new musical or visual instruments and sound generators.
A whirligig is an object that spins or whirls, or has at least one part that spins or whirls. It can also be a pinwheel, spinning top, buzzer, comic weathervane, gee-haw, spinner, whirlygig, whirlijig, whirlyjig, whirlybird, or simply a whirly. They are most commonly powered by the wind but can be hand-, friction- or motor-powered. They can be used as kinetic garden ornaments, and can be designed to transmit sound and vibration into the ground to repel burrowing rodents.
Inflatable castles are temporary inflatable structures and buildings and similar items that are rented for backyard and block party functions, school and church festivals and village fetes and used for recreational purposes, particularly for children, but have been found recently being used for teens and adult parties. The growth in the use of such devices has led to a rental industry that includes inflatable slides, inflatable water slides, obstacle courses, and giant games, carnival games, and more. Inflatables are ideal for portable amusements because they are easy to transport and store.
In aeronautics, an aircraft propeller, also called an airscrew, converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type.
Toy safety is the practice of ensuring that toys, especially those made for children, are safe, usually through the application of set safety standards. In many countries, commercial toys must be able to pass safety tests in order to be sold. In the U.S., some toys must meet national standards, while other toys may not have to meet a defined safety standard. In countries where standards exist, they exist in order to prevent accidents, but there have still been some high-profile product recalls after such problems have occurred. The danger is often not due to faulty design; usage and chance both play a role in injury and death incidents as well.
Monarch High School (MHS) is a public high school located in Coconut Creek, Florida. Monarch is a part of the Broward County Public Schools system, and serves neighborhoods in: Coconut Creek, Deerfield Beach, Margate, and Pompano Beach.
The Omaha Children's Museum is a nonprofit learning and exploration space for young people located at 500 South 20th Street in downtown Omaha, Nebraska. The museum has received a national award from the Association of Science and Technology Museums.
A smart toy is an interactive toy which effectively has its own intelligence by virtue of on-board electronics. These enable it to learn, behave according to preset patterns, and alter its actions depending upon environmental stimuli and user input. Typically, it can adjust to the abilities of the player. A modern smart toy has electronics consisting of one or more microprocessors or microcontrollers, volatile and/or non-volatile memory, storage devices, and various forms of input–output devices. It may be networked together with other smart toys or a personal computer in order to enhance its play value or educational features. Generally, the smart toy may be controlled by software which is embedded in firmware or else loaded from an input device such as a USB flash drive, Memory Stick or CD-ROM. Smart toys frequently have extensive multimedia capabilities, and these can be utilized to produce a realistic, animated, simulated personality for the toy. Some commercial examples of smart toys are Amazing Amanda, Furby and iDog. The first smart-toy was the Mego Corporation's 2-XL robot (2XL), invented in the 1970s
Wind-powered vehicles derive their power from sails, kites or rotors and ride on wheels—which may be linked to a wind-powered rotor—or runners. Whether powered by sail, kite or rotor, these vehicles share a common trait: As the vehicle increases in speed, the advancing airfoil encounters an increasing apparent wind at an angle of attack that is increasingly smaller. At the same time, such vehicles are subject to relatively low forward resistance, compared with traditional sailing craft. As a result, such vehicles are often capable of speeds exceeding that of the wind.
Vollis Simpson was an American "outsider" folk artist known for large kinetic sculptures called "whirligigs", which Simpson made from salvaged metal. He lived and worked in Lucama, North Carolina. Many of his larger pieces are on display at the Vollis Simpson Whirligig Park in Wilson, North Carolina, about 10 miles from Lucama.
Apep is a triple star system containing a Wolf–Rayet binary and a hot supergiant, located in the constellation of Norma. Named after the serpent deity from Egyptian mythology, the star system is surrounded by a vast complex of stellar wind and cosmic dust thrown into space by the high rotation speed of the binary's primary star and formed into a "pinwheel" shape by the secondary star's influence. Ground-based studies of the system in the 2010s concluded that the system was the best-known gamma-ray burst progenitor candidate in the Milky Way galaxy.
