A slingshot or catapult is a small hand-powered projectile weapon. The classic form consists of a Y-shaped frame, with two natural rubber strips or tubes attached to the upper two ends. The other ends of the strips lead back to a pouch that holds the projectile. One hand holds the frame, while the other hand grasps the pocket and draws it back to the desired extent to provide power for the projectile—up to a full span of the arms with sufficiently long bands.
The Magic 8 Ball is a plastic sphere, made to look like an oversized eight ball, that is used for fortune-telling or seeking advice. It was invented in 1946 by Albert C. Carter and Abe Bookman and is currently manufactured by Mattel. The user asks a yes–no question to the ball, then turns it over to reveal an answer that floats up into a window.
In thermodynamics, superheating is the phenomenon in which a liquid is heated to a temperature higher than its boiling point, without boiling. This is a so-called metastable state or metastate, where boiling might occur at any time, induced by external or internal effects. Superheating is achieved by heating a homogeneous substance in a clean container, free of nucleation sites, while taking care not to disturb the liquid.
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 hula hoop is a toy hoop that is twirled around the waist, limbs or neck. It can also be wheeled along the ground like a wheel, with careful execution. They have been used by children and adults since at least 500 BC. The modern hula hoop was inspired by Australian bamboo hoops. Common lore posits the creators of the plastic hoop popularised in the US witnessed Australian children playing with bamboo hoops while driving past in an automobile. The new plastic version was popularized in 1958 by the Wham-O toy company and became a fad.
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.
A water gun is a type of toy gun designed to shoot jets of water. Similar to water balloons, the primary purpose of the toy is to soak another person in a recreational game such as water fight.
A whoopee cushion is a practical joke device involving flatulence humor, which produces a noise resembling human flatulence.
An air vortex cannon is a toy that releases doughnut-shaped air vortices — similar to smoke rings but larger, stronger and invisible. The vortices are able to ruffle hair, disturb papers or blow out candles after travelling several metres.
A Super Ball or Superball is a toy bouncy ball based on a type of synthetic rubber invented in 1964 by chemist Norman Stingley. It is an extremely elastic ball made of Zectron, which contains the synthetic polymer polybutadiene as well as hydrated silica, zinc oxide, stearic acid, and other ingredients. This compound is vulcanized with sulfur at a temperature of 165 °C (329 °F) and formed at a pressure of 3,500 psi (24 MPa). The resulting Super Ball has a very high coefficient of restitution, and if dropped from shoulder level on a hard surface, a Super Ball bounces nearly all the way back; thrown down onto a hard surface by an average adult, it can fly over a three-story building.
Acetone is an organic compound with the formula (CH3)2CO. It is the simplest and smallest ketone. It is a colorless, highly volatile and flammable liquid with a characteristic pungent odor.
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.
A bubble light is a decorative device consisting of a liquid-filled vial that is heated and illuminated by an incandescent light bulb. Because of the liquid's low boiling point, 39.6°C (103.3°F), the modest heat generated by the lamp causes the liquid to boil and bubble up from the vial's base thus creating a decorative effect.
Silly String is a toy of flexible, sometimes brightly colored, plastic string propelled as a stream of liquid from an aerosol can. The solvent in the string quickly evaporates in mid-air, creating a continuous strand. Silly String is often used during weddings, birthday parties, carnivals and other festive occasions, and has also been used by the US military to detect tripwires.
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.
Dulcop International S.p.A. (Dulcop) is an Italian company, founded in 1938, which produces soap bubbles and bubble toys. The company's headquarters is located in San Lazzaro di Savena, Bologna, Italy.
A balloon is a flexible membrane that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, and air. For special tasks, balloons can be filled with smoke, liquid water, granular media, or light sources. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or a nylon fabric, and can come in many different colors. Some early balloons were made of dried animal bladders, such as the pig bladder. Some balloons are used for decorative purposes or entertaining purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. A balloon's properties, including its low density and low cost, have led to a wide range of applications.
A squeaky toy, squeak toy, squeaker toy, or squeeze toy, is a soft, hollow toy made from flexible materials such as rubber or vinyl, and usually equipped with a small device known as a squeaker.
Stretch Screamers was a series of electronic toys by Manley Toys Limited of Hong Kong.
