A firework is classified as a low explosive pyrotechnic device used primarily for aesthetic and entertainment purposes. The most common use of a firework is as part of a fireworks display.
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. Displays are common throughout the world and are the focal point of many different cultural and religious celebrations.
Fireworks were originally invented by the Chinese, for entertainment purposes, as a natural extension of the Chinese invention of gunpowder. In China, they were first made by firework masters who were well respected for their knowledge of the many complex techniques used to create truly dazzling firework displays. Such important events and festivities as New Year's and the Mid-Autumn Moon Festival were and still are times when fireworks are guaranteed sights.
