Pyrotechnic Compositions
Pyrotechnics is the science and craft of creating such things as fireworks, 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'' ("fire") and ''tekhnikos'' ("made by art"). 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 training and licensing must be obtained from local authorities to legally prepare and use proximate ...

Rammstein
Rammstein (, "ramming stone") is a German Neue Deutsche Härte 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 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxidizer
An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or " accepts"/"receives" an electron from a (called the , , or ). In other words, an oxidizer is any substance that oxidizes another substance. The oxidation state, which describes the degree of loss of electrons, of the oxidizer decreases while that of the reductant increases; this is expressed by saying that oxidizers "undergo reduction" and "are reduced" while reducers "undergo oxidation" and "are oxidized". Common oxidizing agents are oxygen, hydrogen peroxide and the halogens. In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction. In the second sense, an oxidizing agent is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate. C ...

Gerb Schematic
GERB ( bg, ГЕРБ, translation=coat of arms, acronym for Citizens for European Development of Bulgaria) is a conservative, populist political party which was the ruling party of Bulgaria between 2009 and 2021. History GERB is headed by former Prime Minister of Bulgaria Boyko Borisov, the former mayor of Sofia, former member of the National Movement Simeon II and former personal guard of Todor Zhivkov in the 1990s. The establishment of the party followed the creation of a non-profit organization with the acronym (in Bulgarian) GERB — ''Citizens for European Development of Bulgaria'', earlier the same year. In early January 2007, and early February 2007, the party came second in public polls on party support with around 14%, trailing the Bulgarian Socialist Party which had around 25%. Its stated priorities are fighting crime and corruption, preserving family as the cornerstone of society and achieving energy independence. GERB won the 2009 European Parliament ele ...

Saxon (firework)
{{other uses, Saxon (other) The Saxon is a rapidly spinning ground-based firework that is basic in design and construction. There are slight variations but typically the Saxon consists of two tubes which are filled with composition and have a clay plug at the end. They are joined in the centre by wooden dowel and pivot at point in the middle. It is driven by exhaust or vents located on the sides of the tube near the end plugs which are at right angles to the tube axis.

Strobe
A strobe light or stroboscopic lamp, commonly called a strobe, is a device used to produce regular flashes of light. It is one of a number of devices that can be used as a stroboscope. The word originated from the Ancient Greek ('), meaning "act of whirling". A typical commercial strobe light has a flash energy in the region of 10 to 150 joules, and discharge times as short as a few milliseconds, often resulting in a flash power of several kilowatts. Larger strobe lights can be used in “continuous” mode, producing extremely intense illumination. The light source is commonly a xenon flash lamp, or ''flashtube'', which has a complex spectrum and a color temperature of approximately 5,600 kelvins. To obtain colored light, colored gels may be used. Scientific explanation of flashtubes Strobe lights usually use flashtubes with energy supplied from a capacitor, an energy storage device much like a battery, but capable of charging and releasing energy much faster.

Gerb (pyrotechnic)
A gerb is a type of firework which produces a jet of sparks, usually lasting between 15 and 60 seconds. It is a thick-walled tube filled with pyrotechnic composition and possessing a choke, which is a narrowing in the tube. Gerbs are often referred to as 'fountains' (spark fountain). Sometimes a small charge of black powder is added to the bottom of a gerb to make it finish with a bang: this charge is known as the 'bounce'. These are commonly used at sporting events. Gerbs intended for use indoors near a proximate audience, such as at a rock concert, typically have shorter durations (from {{frac, 1, 8 to 30 seconds) and heights (4 to 50 feet). Gerbs are usually measured in terms of time and height. For example, a 4×4 burns for 4 seconds at a height of 4 feet.

Flare
A flare, also sometimes called a fusée, fusee, or bengala in some Latin-speaking 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. History 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 dating ...

Meteoroid
A meteoroid () is a small rocky or metallic body in outer space. Meteoroids are defined as objects significantly smaller than asteroids, ranging in size from grains to objects up to a meter wide. Objects smaller than this are classified as micrometeoroids or space dust. Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies such as the Moon or Mars. When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of , aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". Meteors typically become visible when they are about 100 km above sea level. 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. A meteorite is the remains of a meteor ...

Bullet Hit Squib
A bullet hit squib or a blood squib is a practical, pyrotechnic special effect device used in the film industry, theatre productions and first responder moulage training to simulate a bullet wound spurting blood. Typically, the effect is carried out with clothing instead of on bare skin in order to conceal the device. Even if the portrayal is not necessarily accurate or is exaggerated compared to real-life (in the example of the main figure, blood spews out of a thick coat while emitting smoke), filmmakers and the audience have become accustomed to associating this aesthetic with a gunshot wound. A bullet hit squib device comprises a squib (a small, firecracker-like explosive), an electric match, a small pack of simulant (most commonly fake blood), a protective plate and some padding attached to the actor's costume. The device is then connected to a battery and a remote, with which the squib can be triggered by the actor or a crew member, creating the visual effect of a gu ...
