Rubber Band Gun
A rubber band gun is a toy gun used to fire one or more rubber bands (or "elastic bands"). Rubber band guns are often used in live-action games such as Assassins, in which they are common and popular toy weapons. They are also common in offices and classrooms. Rubber band guns have been popular toys that date back to the invention of rubber bands, which were patented in England on March 17, 1845 by Stephen Perry.How rubber bands are made
This reference states that the rubber is vulcanized before it is extruded. The rubber is then "cured" on mandrels. The "Made How" reference appears to directly copy text from other sources, some of which appears to be incorrect. The exact same text regarding Thomas Hancock appears in a 1995 book entitled "CD's, super glue and salsa: how everyday products are made" by Kathleen Witman, Kyung ...

Rubber Band
A rubber band (also known as an elastic band, gum band or lacky band) is a loop of rubber, usually ring or oval shaped, and commonly used to hold multiple objects together. The rubber band was patented in England on March 17, 1845 by Stephen Perry. Most rubber bands are manufactured out of natural rubber or, especially at larger sizes, an elastomer, and are sold in a variety of sizes. Notable developments in the evolution of rubber bands began in 1923 when William H. Spencer obtained a few Goodyear inner tubes and cut the bands by hand in his basement, where he founded Alliance Rubber Company. Spencer persuaded the ''Akron Beacon Journal'' as well as the ''Tulsa World'' to try wrapping their newspapers with one of his rubber bands to prevent them from blowing across lawns. He went on to pioneer other new markets for rubber bands such as: agricultural and industrial applications and a myriad of other uses. Spencer obtained a patent on February 19, 1957 for a new "Method for Maki ...

Potential Energy
In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is the joule, which has the symbol J. The term ''potential energy'' was introduced by the 19th-century Scottish engineer and physicist William Rankine, although it has links to Greek philosopher Aristotle's concept of potentiality. Potential energy is associated with forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space. These forces, that are called ''conservative forces'', can be represented at every point in space by vec ...

K'Nex
K'Nex is a construction toy system founded by Joel Glickman. It was first introduced in America in 1992. K'Nex is designed and produced by K'Nex Industries Inc. of Hatfield, Pennsylvania. K'Nex was purchased by Florida-based company Basic Fun! in 2018. The toy's building system consists of interlocking plastic rods, connectors, blocks, gears, wheels, and other components, which can be assembled to form a wide variety of models, machines, and architectural structures. While K'Nex is designed for children ages 5-12, a larger version, Kid K'Nex, is aimed towards children 5 and younger. The toy has been released and marketed in various stores, as well as online websites. K'Nex has released various sets, educational kits, and models consisting of assorted parts, the last of which includes parts and instructions specifically packaged to be assembled into a specific model. History The concept behind K'Nex was originally conceived by Joel Glickman while attending a wedding. There, h ...

Magazine (firearms)
A magazine 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 cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of semi-au ...

Foregrip
A vertical forward grip or foregrip is a vertical pistol grip mounted on the fore-end of a long-barrel firearm, designed for grasping by the frontal support hand (or "off hand"). Use Forward grips aid in the maneuverability of the firearm, since the natural angle of a person's outstretched hand is more oriented to grasping objects at a vertical angle, rather than a horizontal one perpendicular to the body. Foregrips can decrease accuracy in precision rifle shooting if the shooter tends to "muscle the weapon". Vertical foregrips can have features located inside the inner diameter, such as a deployable bipod inside the grip's housing. The M4 Carbine's with similar weapons' different Grip Pod Systems, AKA "Grip Pods" created in 2003 are still used by the American (Include the US Army, USMC, National Guard, US Air Force, FBI, CIA, DEA, Customs Border Patrol, etc), British and Australian armed forces is such a device. The grip may also have a tactical light and the control sw ...

Sniper
A sniper is a military/paramilitary marksman who engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with high-precision rifles and high-magnification optics, and often also serve as scouts/observers feeding tactical information back to their units or command headquarters. In addition to long-range and high-grade marksmanship, military snipers are trained in a variety of special operation techniques: detection, stalking, target range estimation methods, camouflage, tracking, bushcraft, field craft, infiltration, special reconnaissance and observation, surveillance and target acquisition. Etymology The name "sniper" comes from the verb "to snipe", which originated in the 1770s among soldiers in British India in reference to shooting snipes, a wader that was considered an extremely challenging game bird for hunters due to its alertness, camouflaging color ...

Crank (mechanism)
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning Wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Starting ...

Rotary Cannon
A rotary cannon, rotary autocannon, rotary gun or Gatling cannon, is any large-caliber multiple-barreled automatic firearm that uses a Gatling-type rotating barrel assembly to deliver a sustained saturational direct fire at much greater rates of fire than single-barreled autocannons of the same caliber. The loading, firing and ejection functions are performed simultaneously in different barrels as the whole assembly rotates, and the rotation also permits the barrels some time to cool. The rotating barrels on nearly all modern Gatling-type guns are powered by an external force such as an electric motor, although internally powered gas-operated versions have also been developed. The cyclic multi-barrel design synchronizes the firing/reloading sequence. Each barrel fires a single cartridge when it reaches a certain position in the rotation, after which the spent casing is ejected at a different position and then a new round is loaded at another position. During the cycle, the b ...
