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, a display of the effects produced by firework devices. Fireworks take many forms to produce the four primary effects: noise, light, smoke, as well as floating materials. 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 are generally classified as to where they perform, either as a ground or aerial firework. In the latter case they may provide their own propulsion or be shot into the air by a mortar. The most common feature of fireworks is a paper or pasteboard tube or casing filled with the combustible material, often pyrotechnic stars.
