An air gun or airgun is a gun that using energy from compressed air or other gases that are mechanically pressurized and released as propellant for the chosen projectiles based on the principle of the primitive blowgun. This is in contrast to a firearm, which fires projectiles using energy by burning combustible propellants, most often gunpowder.
Airsoft, also known as survival game in Japan where it was first popularized, is a team-based shooting game in which participants eliminate opposing players out of play by tagging them with spherical plastic projectiles shot from low-power airguns called airsoft guns.
A BB gun is a type of air gun designed to shoot metallic spherical projectiles called BBs, which are approximately the same size as BB-size lead birdshot used on shotguns. Modern BB guns usually have a smoothbore barrel with a 4.5 mm (0.177 in) caliber, and use steel balls that measure 4.3–4.4 mm (0.171–0.173 in) in diameter and 0.33–0.35 g (5.1–5.4 gr) in weight, usually zinc- or copper-plated for corrosion resistance. Some manufacturers still make the slightly larger traditional lead balls that weigh around 0.48–0.50 g (7.4–7.7 gr), which are generally intended for use in rifled barrels.
Toy guns are toys which imitate real guns, but are designed for recreational sport or casual play by children. From hand-carved wooden replicas to factory-produced pop guns and cap guns, toy guns come in all sizes, prices and materials such as wood, metal, plastic or any combination thereof. Many newer toy guns are brightly colored and oddly shaped to prevent them from being mistaken for real firearms.
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.
Nerf is a toy brand formed by Parker Brothers and currently owned by Hasbro. Most of the toys are a variety of foam-based weaponry, with other Nerf products including balls for sports such as American football, basketball, and baseball. Their best known toys are their dart guns that shoot ammunition made from "Nerf foam". Their primary slogan, introduced in the 1990s, is "It's Nerf or Nothin'!". Annual revenues under the Nerf brand are approximately US$400 million.
A hydrogel is a biphasic material, a mixture of porous, permeable solids and at least 10% by weight or volume of interstitial fluid composed completely or mainly by water. In hydrogels the porous permeable solid is a water insoluble three dimensional network of natural or synthetic polymers and a fluid, having absorbed a large amount of water or biological fluids. These properties underpin several applications, especially in the biomedical area. Many hydrogels are synthetic, but some are derived from nature. The term 'hydrogel' was coined in 1894.
Super Soaker is an American brand of recreational water gun that uses manually-pressurized air to shoot water with greater power, range, and accuracy than conventional squirt pistols. The Super Soaker was invented in 1989 by engineer Lonnie Johnson. The prototype combined PVC pipe, acrylic glass, and an empty plastic soda bottle.
Alginic acid, also called algin, is a naturally occurring, edible polysaccharide found in brown algae. It is hydrophilic and forms a viscous gum when hydrated. With metals such as sodium and calcium, its salts are known as alginates. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular, or powdered forms.
Entertech was a brand of battery-powered motorized water guns sold in the United States from 1985 to 1990 by the now-defunct LJN. Unlike the colorful designs of many of the simple hand powered pump water guns of that time, most of the Entertech water guns were manufactured from black plastics with a matte finish to resemble real firearms.
Airsoft guns are replica toy guns used in airsoft sports. They are a special type of low-power smoothbore air guns designed to shoot non-metallic spherical projectiles (pb) often colloquially referred to as "BBs", which are typically made of plastic or biodegradable resin materials. Airsoft gun powerplants are designed to have low muzzle energy ratings and the pellets have significantly less penetrative and stopping powers than conventional airguns, and are generally safe for competitive sporting and recreational purposes if proper protective gear is worn.
Sodium polyacrylate (ACR, ASAP, or PAAS), also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [−CH2−CH(CO2Na)−]n and has broad applications in consumer products. This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. It is a chemical polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water. When dissolved in water, it forms a thick and transparent solution due to the ionic interactions of the molecules. Sodium polyacrylate has many favorable mechanical properties. Some of these advantages include good mechanical stability, high heat resistance, and strong hydration. It has been used as an additive for food products including bread, juice, and ice cream.
The Oozinator is a toy water gun manufactured by Hasbro, Inc. It is a member of the Super Soaker family, which includes 10 other squirt-gun toys. It gained notoriety after its release due to its ability to discharge a viscous compound that resembled human semen, as well as its suggestive television advertisements that depicted said compound being forcefully ejected onto unwilling children.
Lonnie George Johnson is an American inventor, aerospace engineer, and entrepreneur, whose work includes a U.S. Air Force-term of service and a twelve-year stint at NASA, where he worked at the Jet Propulsion Laboratory. He invented the Super Soaker water gun in 1989, which has been among the world's bestselling toys ever since.
A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers that can absorb and retain extremely large amounts of a liquid relative to its own mass.
Expandable water toys are novelty items made from a superabsorbent polymer. They are toys that expand after putting them into water for anything between a few hours up to several days, depending on size. They shrink in saltwater or when exposed to air. They are made from polymers that can absorb and retain extremely large amounts of a liquid relative to their own mass.
Water crystal gel or water beads or gel beads is any gel which absorbs and contains a large amount of water. Water gel is usually in spherical form and composed of a water-absorbing superabsorbent polymer such as a polyacrylamide.
Water Warriors is a water gun brand owned by Buzz Bee Toys that was created by the company in 2003. The toy line comprises a large variety of pressurized water guns, as well as smaller water guns for younger children.
Common hydrogel agriculture's ingredient is potassium polyacrylate or sodium polyacrylate. As a superabsorbent material, it can absorb plenty of water and turn water to gel to store water.
A gel ball blaster, also known as a gel gun, gel shooter, gel marker, hydro marker, hydro blaster, water bead blaster or gelsoft, is a toy gun similar in design to airsoft guns, but the projectiles they shoot are 6–8 mm (0.24–0.31 in) superabsorbent polymer water beads, which are often sold commercially as moisture retainers for gardening and pot/vase floriculture.
