Fun facts about fireworks:
Fireworks are a class of low explosive pyrotechnic devices used for
aesthetic and entertainment purposes. They are most commonly used in
fireworks displays (also called a fireworks show or pyrotechnics),
combining a large number of devices in an outdoor setting. Such displays
are the focal point of many cultural and religious celebrations. Fireworks
take many forms to produce four primary effects: noise, light, smoke, and
floating materials (confetti most notably). They may be designed to burn
with colored flames and sparks including red, orange, yellow, green, blue,
purple and silver.
