| Fireworks are a class of explosive pyrotechnic devices used
for aesthetic and entertainment purposes. The most common use of
a firework is as part of a fireworks display. A fireworks event
(also called a fireworks show or pyrotechnics) is a display of
the effects produced by firework devices. Fireworks competitions
are also regularly held at a number of places. Fireworks
(devices) 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 the world and are the
focal point of many cultural and religious celebrations.
Fireworks were invented in China in the 7th century to scare
away evil spirits, as a natural extension of one of the Four
Great Inventions of ancient China, gunpowder. Such important
events and festivities as Chinese New Year and the Mid-Autumn
Moon Festival were and still are times
