Pyrotechnic Fuels
Pyrotechnics is the science and craft of creating fireworks, but also includes safety matches, oxygen candles, explosive bolts (and other fasteners), parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name comes from the Greek words ''pyr'' (πυρ; 'fire') and ''technikós'' (τεχνικός; 'artistic'). Improper use of pyrotechnics could lead to pyrotechnic accidents. People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians. Proximate pyrotechnics Explosions, flashes, smoke, flames, fireworks and other pyrotechnic-driven effects used in the entertainment industry are referred to as proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to an audience. In the majority of jurisdictions, special train ...

Rammstein
Rammstein (, "ramming stone") is a German band formed in Berlin in 1994. The band's lineup—consisting of lead vocalist Till Lindemann, lead guitarist Richard Kruspe, rhythm guitarist Paul Landers, bassist Oliver Riedel, drummer Christoph Schneider, and keyboardist Christian "Flake" Lorenz—has remained unchanged throughout their history, along with their approach to songwriting, which consists of Lindemann writing and singing the lyrics over instrumental pieces the rest of the band has completed beforehand. Prior to their formation, some members were associated with the punk rock acts Feeling B and First Arsch. After winning a local contest, Rammstein was able to record Demo (music), demos and send them to different record labels, eventually signing with Motor Music. Working with producer Jacob Hellner, they released their debut album ''Herzeleid'' in 1995. Though the album initially sold poorly, the band gained popularity through their live performances and the album e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sparklers
A sparkler is a type of hand-held firework that burns slowly while emitting bright, colored sparks. It burns in high temperature (over 1000°C), so it can be very dangerous. Sparklers are particularly popular with children. In the United Kingdom, a sparkler is often used by children at bonfire and fireworks displays on Guy Fawkes Night, the fifth of November, and in the United States on Independence Day. They are called ''phuljhadi'' in Hindi and are especially popular during the Diwali festival. Composition Sparklers are generally formed around a thin non-combustible metallic wire, about long, that has been dipped in a thick batter of slow-burning pyrotechnic composition and allowed to dry. The combustible coating contains the following components; multiple ingredients can be used: * Metallic fuel, main reactive ingredient; type of metals influences the color of sparks; size of particles influences shape and size of the sparks ** Aluminium, magnesium or magnalium, fo ...

Flares
A flare, also sometimes called a fusée, fusee, or bengala, bengalo in several European countries, is a type of pyrotechnic that produces a bright light or intense heat without an explosion. Flares are used for distress signaling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or handheld percussive tubes. Origin The earliest recorded use of gunpowder for signaling purposes was the 'signal bomb' used by the Chinese Song Dynasty (960–1279) as the Mongol-led Yuan Dynasty (1271–1368) besieged Yangzhou in 1276. These soft-shelled bombs, timed to explode in midair, were used to send messages to a detachment of troops far in the distance. Another mention of the signal bomb appears in a text da ...

Model Rocket
A model rocket is a small rocket designed to reach low altitudes (e.g., for a model) and #Model rocket recovery methods, be recovered by a variety of means. According to the United States National Association of Rocketry, National Association of Rocketry (NAR)'s Safety Code, model rockets are constructed out of lightweight and non metallic parts. The materials are typically paper, cardboard, balsa wood or plastic. The code also provides guidelines for motor use, launch site selection, launch methods, launcher placement, recovery system design and deployment and more. Since the early 1960s, a copy of the Model Rocket Safety Code has been provided with most model rocket kits and motors. Despite its inherent association with extremely flammable substances and objects with a pointed tip traveling at high speeds, model rocketry historically has proven to be a very safe hobby and has been credited as a significant source of inspiration for children who have eventually become scient ...

General Public
In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the ''Öffentlichkeit'' or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, and suffered more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder. Etymology and definitions The name "public" originates with the Latin '' publicus'' (also '' poplicus''), from ''populus'', to the English word ' populace', and in general denotes some mass population ("the ...

Electric Match
An electric match is a device that uses an externally applied electric current to ignite a combustible compound. Electric matches use a bridgewire consisting of a heating element to ignite a pyrogen, which is a quantity of readily ignited pyrotechnic initiator composition. Electric matches can be used in any application where source of heat is needed at a precisely controlled point in time, typically to ignite a propellant or explosive. Examples include airbags, pyrotechnics, and military or commercial explosives. Design Electric matches consist of two parts, a bridgewire and a Pyrogen (pyrotechnics), pyrogen. The bridgewire is a heating element, typically in the form of a loop or coil of thin wire, which is encased in the pyrogen, which is a quantity of readily ignited pyrotechnic initiator composition. If the pyrogen is sufficiently conductive, it can act as the bridgewire as well. Electric matches also come with provisions for attaching an electric current source, and they ...

Meteoroid
A meteoroid ( ) is a small rocky or metallic body in outer space. Meteoroids are distinguished as objects significantly smaller than ''asteroids'', ranging in size from grains to objects up to wide. Objects smaller than meteoroids are classified as ''micrometeoroids'' or ''space dust''. Many are fragments from comets or asteroids, whereas others are impact event, collision impact space debris, debris ejected from bodies such as the Moon or Mars. The visible passage of a meteoroid, comet, or asteroid atmospheric entry, entering Earth's atmosphere is called a meteor, and a series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. An estimated 25 million meteoroids, micrometeoroids and other space debris enter Earth's atmosphere each day, which results in an estimated 15,000 tonnes of that material entering the atmosphere each year. A ''meteorite'' is the remains of a meteoroid that has surv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
