Big-Bang Cannon
The Big-Bang Cannon, also known as the Calcium Cannon, is an American toy cannon first manufactured in the early 20th-century. Numerous consumer fireworks injuries convinced a physics professor at Lehigh University in Bethlehem, Pennsylvania to patent a "Gas Gun" in 1907, and the manufacturing of Big-Bang Cannons started in 1912, from the Gas Cannon Company. History In 1916, the name was changed to the Toy Cannon Works. In 1924, the company changed names again, to The Conestoga Company, Inc. An assistant professor from the same physics department at Lehigh was the company founder and owner until 1955. The Conestoga Company manufactures nineteen models of Big-Bang Cannon in Allentown, Pennsylvania. A bombing plane, tank, boat and pistol were manufactured during the 1920s, firing on the same principle as the cannons. 1930s designs included a Giant Roller Coaster, Ro-To-Top, Spinning Top, Field Glasses and G-Gun. Repurposed for toymaking, the historic 4-story wood and brick pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighters
A lighter is a portable device which uses mechanical or electrical means to create a controlled flame, and can be used to ignite a variety of flammable items, such as cigarettes, butane gas, fireworks, candles, or campfires. A lighter typically consists of a metal or plastic container filled with a flammable liquid, a compressed flammable gas, or in rarer cases a flammable solid (e.g. rope in a trench lighter); a means of ignition to produce the flame; and some provision for extinguishing the flame or else controlling it to such a degree that users may extinguish it with their breath. Alternatively, a lighter can be one that uses electricity to create an electric arc using the created plasma as the source of ignition or a heating element can be used in a similar vein to heat the target to its ignition temperatures, as first formally used by Friedrich Wilhelm Schindler to light cigars and now more commonly seen incorporated into the automobile auxiliary power outlet to igni ...

Fireworks
Fireworks are Explosive, low explosive Pyrotechnics, pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays (also called a fireworks show or pyrotechnics), combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious Celebration (party), celebrations, though mismanagement could lead to List of fireworks accidents and incidents, fireworks accidents. Fireworks take many forms to produce four primary effects: noise, light, smoke, and floating materials (confetti most notably). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple and silver. They are generally classified by where they perform, either 'ground' or 'aerial'. Aerial fireworks may have their own Air propulsion, propulsion (skyrocket) or be shot into the air by a Mortar (weapon), mortar (aerial shell). Most fireworks consist of a paper or ...

Companies Based In Allentown, Pennsylvania
A company, abbreviated as co., is a legal entity representing an association of legal people, whether natural, juridical or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Over time, companies have evolved to have the following features: "separate legal personality, limited liability, transferable shares, investor ownership, and a managerial hierarchy". The company, as an entity, was created by the state which granted the privilege of incorporation. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is to generate sales, revenue, and profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duties according to the publicly declared incorporation pu ...

Carbides
In chemistry, a carbide usually describes a compound composed of carbon and a metal. In metallurgy, carbiding or carburizing is the process for producing carbide coatings on a metal piece. Interstitial / Metallic carbides The carbides of the group 4, 5 and 6 transition metals (with the exception of chromium) are often described as interstitial compounds. These carbides have metallic properties and are refractory. Some exhibit a range of stoichiometries, being a non-stoichiometric mixture of various carbides arising due to crystal defects. Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: *When the metal atoms are cubic close-packed, (ccp), then filling all of the octahedral interstices with carbon achieves 1: ...

Air Vortex Cannon
An air vortex cannon is a toy that releases doughnut-shaped air vortices — similar to smoke rings but larger, stronger and invisible. The vortices can ruffle hair, disturb papers or blow out candles after travelling several metres. An air vortex cannon can be made easily at home, from just a cardboard box.The Vortex Cannon - Student Science at YouTube. Accessed February 2013. Air cannons are used in some s such as to spook or surprise visitors. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potato Cannon
A potato cannon, also known as a potato gun or potato launcher, is a pipe-based cannon that uses air pressure (pneumatic), or combustion of a flammable gas (aerosol, propane, etc.), to fire projectiles, usually potatoes. A simple design consists of a pipe sealed on one end, with a reducer on the other end to lower the diameter of the pipe, which has the corresponding lower-diameter pipe attached to it, called the barrel. Generally, the operator loads the projectile into the barrel, then utilizes a fuel or air pressure (or sometimes both) to propel the projectile out of the cannon. The potato cannon can trace its origin to the World War II-era Holman Projector, which was a shipboard anti-aircraft weapon. Operation methods Combustion Combustion powered potato cannons typically have the least complex designs; the four basic elements of which are: * A fuel-air mixture * A combustion chamber * An ignition source * A barrel In order to fire, the operator loads a projectile into the bar ...

Vortex Ring Gun
The vortex ring gun is an experimental non-lethal weapon for crowd control that uses high-energy vortex rings of gas to knock down people or spray them with marking ink or other chemicals. The concept was explored by the US Army starting in 1998, and by some commercial firms. Knockdown of distant individuals currently seems unlikely even if the rings are launched at theoretical maximum speed. As for the delivery of chemicals, leakage during flight is still a problem. Weapons based on similar principles but different designs and purposes have been described before, typically using acetylene-air or hydrogen–oxygen explosions to create and propel the vortices. Operation In a typical concept, a blank cartridge is fired into a gun barrel that has a diverging nozzle screwed onto the muzzle. In the nozzle, the short pulse of high pressure gas briefly accelerates to a supersonic exit velocity, whereupon a portion of the exhaust transforms from axial flow into a subsonic, high ...

Bubble Ring
A bubble ring, or toroidal bubble, is an underwater vortex ring where an air bubble occupies the core of the vortex, forming a ring shape. The ring of air as well as the nearby water spins Toroidal and poloidal, poloidally as it travels through the water, much like a flexible bracelet might spin when it is rolled on to a person's arm. The faster the bubble ring spins, the more stable it becomes. The physics of vortex rings are still under active study in fluid dynamics. Devices have been invented which generate bubble vortex rings. Physics As the bubble ring rises, a lift force pointing downward that is generated by the vorticity acts on the bubble in order to counteract the buoyancy force. This reduces the bubble's velocity and increases its diameter. The ring becomes thinner, despite the total volume inside the bubble increasing as the external water pressure decreases. Bubble rings fragment into rings of spherical bubbles when the ring becomes thinner than a few millimetres. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boga (noisemaker)
A bamboo cannon (, Jawi script, Jawi: مريام بولوه ; ; , Indonesian language, Indonesian: ''meriam bambu'', Javanese language, Javanese: ''mercon bumbung'') is a type of home-made firecracker which is popular during the Eid al-Fitr, Eid season in Malaysia and Indonesia, as well as during New Year's Eve celebrations in the Philippines. Operation A typical bamboo cannon consists of a large bamboo node or tube containing some water to which a little calcium carbide is added. The carbide reacts immediately with the water releasing acetylene gas, which has the widest range of explosive limit of any common chemical and a very low minimum ignition energy, ignition energy. A sharp report is produced when a flame is introduced into the bamboo chamber. However, the low density of the acetylene/air mixture is such that the total combustion energy is quite low and weak containers such as bamboo or even glass rarely shatter. Adding too much carbide does not increase the energy of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferrocerium
Ferrocerium (also known in Europe as Auermetall) is a synthetic pyrophoric alloy of mischmetal (cerium, lanthanum, neodymium, other trace lanthanides and some iron – about 95% lanthanides and 5% iron) hardened by blending in oxides of iron and/or magnesium. When struck with a harder material, friction produces hot fragments that oxidize rapidly when exposed to the oxygen in the air, producing sparks that can reach temperatures of . The effect is due to the low ignition temperature of cerium, between . Ferrocerium has many commercial applications, such as the ignition source for lighters, strikers for gas welding and cutting torches, deoxidization in metallurgy, and ferrocerium rods. Because of ferrocerium's ability to ignite in adverse conditions, rods of ferrocerium (also called ferro rods, spark rods, and flint-spark-lighters) are commonly used as an emergency firelighting device in survival kits. The ferrocerium is referred to as a "flint" in this case, as bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
