Pyrotechnics


Pyrotechnics is the science of using materials capable of undergoing self-contained and self-sustained exothermic chemical reactions for the production of heat, light, gas, smoke and/or sound. Its etymology stems from the Greek words pyro ("fire") and tekhnikos ("made by art"). Pyrotechnics include not only the manufacture of fireworks but items such as safety matches, oxygen candles, explosive bolts and fasteners, components of the automotive airbag and gas pressure blasting in mining, quarrying and demolition.

Individuals responsible for the safe storage, handling, and functioning of pyrotechnic devices are referred to as pyrotechnicians.

Explosions, flashes, smoke, flames, fireworks or other pyrotechnic driven effects used in the entertainment industry are referred to as theatrical special effects, special effects, or 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 pyrotechnics.

Many musical groups use pyrotechnics to enhance their live shows. Pink Floyd were without a doubt the innovators of pyrotechnic use in concerts. For instance, at the climax of their song "Careful with That Axe, Eugene", a blast of smoke was set off at the back of the stage. Bands such as The Who, KISS and Queen, soon followed use of pyrotechnics in their shows. Michael Jackson attempted using pyrotechnics in a 1984 Pepsi advertisement, where a stray spark caused a small fire in his hair. German industrial metal band Rammstein are renowned for their large variety of pyrotechnics, which range from flaming costumes to face-mounted flamethrowers. Nightwish, Lordi and Green Day are also known for their vivid pyrotechnics in concert. Many professional wrestlers have also used pyrotechnics as part of their entrances to the ring.
