Pyrotechnic compositionA pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a combination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction.
SkyrocketA skyrocket, also known as a rocket, is a type of firework that uses a solid-fuel rocket to rise quickly into the sky; a bottle rocket is a small skyrocket. At the apex of its ascent, it is usual for a variety of effects (stars, bangs, crackles, etc.) to be emitted. Skyrockets use various stabilisation techniques to ensure the flight follows a predictable course, often a long stick attached to the side of the motor, but also including spin-stabilisation or fins.
List of Chinese inventionsA bronze Chinese crossbow trigger mechanism with a butt plate (the wooden components have since eroded and disappeared), inlaid with silver, from either the late Warring States period (403–256 BC) or the early Han dynasty (202 BC – AD 220)China has been the source of many innovations, scientific discoveries and inventions. This includes the Four Great Inventions: papermaking, the compass, gunpowder, and early printing (both woodblock and movable type).
PyrotechnicsPyrotechnics 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.
DiwaliDipavali (IAST: Dīpāvalī), commonly known as Diwali (), is the Hindu festival of lights, with variations celebrated in other Indian religions such as Jainism and Sikhism. It symbolises the spiritual victory of Dharma over Adharma, light over darkness, good over evil, and knowledge over ignorance. Diwali is celebrated during the Hindu lunisolar months of Ashvin (according to the amanta tradition) and Kārtika – between around mid-October and mid-November.
ExplosiveSubstance that can explode Demonstration of the explosive properties of three different explosives; four explosions are demonstrated. Three are conducted on a solid marble base, and one is conducted on the demonstrator's hand; each is initiated by a splint. An explosive is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure.List of fireworks accidents and incidentsThis is a list of fireworks accidents and incidents, including pyrotechnics fire and explosion. The list is sortable by casualties and date.
CombustionCombustion, or burning, is a high-temperature exothermicredoxchemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion does not always result in fire, because a flame is only visible when substances undergoing combustion vaporize, but when it does, a flame is a characteristic indicator of the reaction.
PaperPaper is a thin sheet of matted cellulosefibers. Largely derived from lignocellulose, paper is created from a pulp dissolved into a slurry that is drained and dried into sheets. Different types of paper are defined by constituent fiber, paper pulp, sizing, coating, paper size, paper density and grammage.
Mortar (weapon)A mortar today is usually a simple, lightweight, man-portable, muzzle-loaded cannon consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically, mortars were heavy siege artillery.
ConfettiConfetti are small pieces or streamers of paper, mylar or metallic material, usually thrown at celebrations, especially parades and weddings. The origins are from the Latinconfectum, with confetti the plural of Italianconfetto, small sweet.
Shell (projectile)A shell, in a modern military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. A shell can hold a tracer.
