A whistle is an instrument which produces sound from a stream of gas, most commonly air. It may be mouth-operated, or powered by air pressure, steam, or other means. Whistles vary in size from a small slide whistle or nose flute type to a large multi-piped church organ.
A model aircraft is a physical model of an existing or imagined aircraft, and is built typically for display, research, or amusement. Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models.
Singing sand, also called whistling sand, barking sand or singing dune, is sand that produces sound. The sound emission may be caused by wind passing over dunes or by walking on the sand.
An inflatable is an object that can be inflated with a gas, usually with air, but hydrogen, helium, and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags, and inflatable space habitats employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, blowing, and suction.
A whoopee cushion is a practical joke device, which emulates the sound of flatulence.
A flue pipe is an organ pipe that produces sound through the vibration of air molecules, in the same manner as a recorder or a whistle, in a pipe organ. Air under pressure is driven through a flue and against a sharp lip called a labium, causing the column of air in the pipe to resonate at a frequency determined by the pipe length. Thus, there are no moving parts in a flue pipe. This is in contrast to reed pipes, whose sound is driven by beating reeds, as in a clarinet.
An organ pipe is a sound-producing element of the pipe organ that resonates at a specific pitch when pressurized air is driven through it. Each pipe is tuned to a note of the musical scale. A set of organ pipes of similar timbre comprising the complete scale is known as a rank; one or more ranks constitutes a stop.
Sweep is a British puppet and television character popular in the United Kingdom, United States, Canada, Australia, Ireland, New Zealand and other countries.
A steam whistle is a device used to produce sound in the form of a whistle using live steam, which creates, projects, and amplifies its sound by acting as a vibrating system.
A toy balloon or party balloon is a small balloon mostly used for decoration, advertising and as a toy. Toy balloons are usually made of rubber or aluminized plastic and inflated with air or helium. They come in a great variety of sizes and shapes but are most commonly 10 to 30 centimetres in diameter. Toy balloons are not considered to include "sky lanterns", although these too are or were used as child toys in some parts of the world.
Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine investigation for hearing loss usually involves an audiogram which shows threshold levels relative to a normal.
Littlest Pet Shop is a toy franchise and cartoon series owned by Hasbro and currently under license with Basic Fun!. The original toy series was produced by Kenner in the early 1990s. An animated television series was made in 1995 by Sunbow Productions and Jean Chalopin Creativite et Developpement, based on the franchise.
A stress ball or hand exercise ball is a malleable toy, usually not more than 7 centimetres (2.8 in) in diameter. It is squeezed in the hand and manipulated by the fingers, ostensibly to relieve stress and muscle tension or to exercise the muscles of the hand.
A cat organ, also called cat piano, is a hypothetical musical instrument which consists of a line of cats fixed in place with their tails stretched out underneath a keyboard so that they cry out when a key is pressed. The cats would be arranged according to the natural tone of their voices.
Weatherstripping is the process of sealing openings such as doors, windows, and trunks from the waters above. The term can also refer to the materials used to carry out such sealing processes. The goal of weatherstripping is to prevent rain and water from entering entirely or partially and accomplishes this by either returning or rerouting water. A secondary goal of weatherstripping is to keep interior air in, thus saving energy on heating and air conditioning.
The Auburn Rubber Company was a rubber products manufacturer best known for its line of children's toys. It was probably the largest producer of rubber and vinyl toys in the world, though Norway's Tomte Laerdal, Finland's Plasto, and Sweden's Galanite were major European producers.
Toys specifically marketed for dogs to play with come in many varieties, including dog bones, puppy toys, balls, tug toys, training aids, squeaky toys, discs and frisbees, plush toys, and sticks.
Henry Dagg is a sound sculptor and builder of experimental musical instruments who formerly worked as a sound engineer for the BBC. His works include a pin barrel harp or sharpsichord which was commissioned for the English Folk Dance and Song Society, a pair of steel sculptural musical gates for Rochester Independent College and an artificial "cat organ", which he played to the amusement of an audience of celebrities at a garden party hosted by Prince Charles.
A vessel flute is a type of flute with a body which acts as a Helmholtz resonator. The body is vessel-shaped, not tube- or cone-shaped; that is, the far end is closed.
Libuše Niklová was a Czech toy designer and national treasure. A world-renowned designer and innovator, she created over 230 original toys. Well-known are her rubber figurines, accordion animals, and inflatable toys. Her work is represented in museum collections around the world, including at the Musée des Arts décoratifs in Paris, the Museum of Modern Art in New York, the Victoria and Albert Museum in London, the National Museum of Modern Art in Tokyo, and the Museum of Decorative Arts in Prague in Prague. In 2012, on the occasion of the annual Czech Grand Design Awards, she was the first female designer ever to be inducted into the Hall of Fame.
