Description
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. Fireworks take many forms to produce four primary effects: noise, light, smoke, and floating materials. They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple and silver.
