Nerf Blaster
A Nerf Blaster or Nerf Gun is a toy gun made by Hasbro that fires foam darts, arrows, discs, or foam balls. “Nerf blaster” or more commonly “Nerf gun” are often used to describe the toy. Nerf blasters are manufactured in multiple forms; the first Nerf blasters emerged in the late 1980s with the release of the Nerf Blast-a-Ball (1989) and the Sharpshooter (1992). Today, Hasbro has produced over twenty unique lines of Nerf-brand blasters, with each line centered on a particular theme or type of ammunition. Hasbro has also produced Nerf blasters based on specific franchises, including Marvel Comics, ''Star Wars'', ''G.I. Joe'', ''Fortnite'', ''Transformers'', ''Overwatch'', ''Halo Infinite'', ''Roblox'' and ''Minecraft''. Nerf blasters are available in several international marketplaces, although some blasters have their names changed or are not sold in certain countries due to laws surrounding toy safety franchises. Most Nerf brands are packaged with a set of the ammunitio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nerf N-Strike Vulcan
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 (referred to by Hasbro as "blasters") that shoot ammunition made from "Nerf foam" (partially reticulated polyether type polyurethane foam). Their primary slogan, introduced in the 1990s, is ''"It's Nerf or Nothin'!"''. Annual revenues under the Nerf brand are approximately . History Parker Brothers originally developed Nerf, beginning with a polyurethane foam ball. In 1969, Reyn Guyer, a Minnesota-based games inventor, and Minnesota Vikings kicker Fred Cox came to the company with a football game that was safe for indoor play, and after studying it carefully, Parker Brothers decided to eliminate everything but the foam ball. The inventors' in-house name for the ball was the " falsie-ball," re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paintball
Paintball is a competitive sport, competitive team sport, team shooting sport in which players eliminate opponents from play by hitting them with spherical dye-filled gelatin capsules called Paintball equipment#Paintballs, paintballs that break upon impact. Paintballs are usually shot using low-energy air gun, air weapons called paintball markers that are powered by compressed air or carbon dioxide and were originally designed for remotely marking trees and cattle. The game was invented in Henniker, New Hampshire, Henniker, New Hampshire, June 27, 1981, by Hayes Noel, a Wall Street stock trader, and Charles Gaines (writer), Charles Gaines, an outdoorsman and writer. A debate arose between the two men about whether a city-dweller had the instinct to survive in the woods against someone who had spent his youth hunting, fishing, and building cabins. A friend of the pair chanced upon an advertisement for ''Nel-Spot'' cattle marking guns in a farm catalogue and they were inspired ...

Chute (gravity)
A chute is a vertical or inclined plane, channel, or passage through which objects are moved by means of gravity. Landform A chute, also known as a race, flume, cat, or river canyon, is a steep-sided passage through which water flows rapidly. Akin to these, man-made chutes, such as the timber slide and log flume, were used in the logging industry to facilitate the downstream transportation of timber along rivers. These are no longer in common use. Man-made chutes may also be a feature of spillways on some dams. Some types of water supply and irrigation systems are gravity fed, hence chutes. These include aqueducts, puquios, and acequias. Building chutes Chutes are in common use in tall buildings to allow fast and efficient transport of items and materials from the upper floors to a central location on one of the lower floors, especially the basement. Chutes may be of a round, square or rectangular cross-section at the top and/or the bottom. * Laundry chutes in hotels are pl ...

Projectile
A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow, stone released from catapult). In ballistics, mathematical equations of motion are used to analyze projectile trajectories through launch, flight, and impact. Motive force Blowguns and pneumatic rifles use compressed gases, while most other guns and cannons utilize expanding gases liberated by sudden chemical reactions by propellants like smokeless powder. Light-gas guns use a combination of these mechanisms. Railguns utilize electromagnetic fields to provide acceleration along the entire length of the device, greatly increasing the muzzle velocity. Some projectiles provide propulsion during flight by means of a rocket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magazine (firearms)
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridge (firearms), cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the gun barrel, barrel chamber (firearms), chamber by the firearm's moving action (firearms), action. The detachable magazine is sometimes colloquially referred to as a "clip (ammunition), clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder. Magazines come in many shapes and sizes, from integral tubular magazines on lever-action and pump-action rifles and shotguns, that may hold more than five rounds, to detachable box magazines and drum magazines for automatic rifles and light machine guns, that may h ...

Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air in vehicle tires and shock absorbers are commonly used for improved traction and reduced vibration. Compressed air is an important medium for the transfer of energy in industrial processes and is used for power tools such as air hammer (fabrication), air hammers, Jackhammer, drills, power wrench, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater diving, underwater divers. The diver may carry it in a high-pressure diving cylinder, or surface supplied diving, supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigger (firearms)
A trigger is a mechanism (engineering), mechanism that Actuator, actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a animal trap, trap, a power tool, or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flat or slightly curved lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on crossbow#Medieval Europe, medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer ...

Flywheel
A flywheel is a mechanical device that 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 (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical Inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical veloc ...

Plunger (hydraulics)
A plunger is a Cylinder, cylindrical rod used to transmit Hydraulics, hydraulic compression force. It is characterized by its length being much greater than its diameter, and it is thus distinguished from a regular piston (where the working surface is larger than the thickness of the rod, i.e. more like a Disk (mathematics), disk). They are mainly used as part of certain types of pumps and hydraulic machines. Plungers are used for Fluid mechanics, fluid-mechanical power transmission in pumps (Plunger pump, plunger pumps), Hydraulic transmission, hydraulic gearboxes, high-pressure diesel Injection pump, injection pumps, Hydraulic press, hydraulic workshop presses and Jack (device), jacks, and other equipment, and are distinguished in fluid mechanics by being a piston without moving seals. The seals are instead located in the wall through which the plunger slides (as opposed to Piston ring, piston rings on a piston). Plungers are often supplied with a suitable stationary plunger bus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propulsion
Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid. The term is derived from two Latin words: ''wikt:pro, pro'', meaning'' before'' or ''forward''; and ''wikt:pellere, pellere'', meaning ''to drive''. A propulsion system consists of a source of mechanical power, and a ''propulsor'' (means of converting this power into propulsive force). Plucking a guitar string to induce a vibration, vibratory translation is technically a form of propulsion of the guitar string; this is not commonly depicted in this vocabulary, even though human muscles are considered to propel the fingertips. The motion of an object moving through a gravitational field is affected by the field, and within some frames of reference physicists speak of the gravitational field generating a force upon the object, but for general relativity, deep the ...

Ammo
Ammunition, also known as ammo, is the material fired, scattered, dropped, or detonated from any weapon or weapon system. The term includes both expendable weapons (e.g., bombs, missiles, grenades, land mines), and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across differe ...
