Fireworks Fireworks Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. The most common use of a firework is as part of a fireworks display (also called a fireworks show or pyrotechnics), a display of the effects produced by firework devices. Fireworks competitions are also regularly held at a number of places. Fireworks take many forms to produce the four primary effects: noise, light, smoke, and floating materials (confetti for example). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple, and silver. Displays are common throughout
Isotopes of barium exceptions are Ba, which has a half-life of 10.51 years, Ba (11.5 days), and Ba (2.55 minutes), which is the decay product of Cs (30.17 years, and a common fission product). Barium-114 is predicted to undergo cluster decay, emitting a nucleus of stable C to produce Sn. However this decay is not yet observed; the upper limit on the branching ratio of such decay is 0.0034%. Isotopes of barium Naturally occurring barium (Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, recently identified as being unstable by geochemical means (from analysis of the
