Fireworks are a kind of low explosive pyrotechnic equipment used for aesthetic and entertainment purposes. The most common use of fireworks is as part of a fireworks show (also known as a fireworks show or fireworks show), which is the display of effects produced by fireworks equipment. Fireworks competitions are also held regularly in many places.

Fireworks take many forms to produce four main effects: noise, light, smoke and floats (such as confetti). They may be designed to burn colored flames and sparks, including red, orange, yellow, green, blue, purple and silver. Exhibitions are common all over the world and are the focus of many cultural and religious celebrations.

Fireworks was invented in the middle ages of the 7th century in China with the aim of eliminating demons. It is one of the four great inventions in ancient China, the natural application of gunpowder. Important events and celebrations, such as the Lunar New Year and the Mid Autumn Festival, are and still are a time to ensure fireworks. China is the world's largest producer and exporter of fireworks.

Fireworks are generally classified according to the location of their performances, including ground fireworks or air fireworks. In the latter case, they may provide their own propulsion (soaring rockets) or be fired into the air by mortars (aircraft).

The most common feature of fireworks is a paper or cardboard board or sleeve filled with combustible materials (usually fireworks stars). Many of these tubes or shells are usually combined to produce a variety of shiny shapes, usually of various colors, when lit. Rockets are a common form of fireworks, although the first rockets were used in war. However, the aviation shell is the foundation of today's commercial aviation display. In the United States, the smaller Festival ball for consumers is called Festival ball. This rocket technology has also been used for mail delivery and propulsion of most model rockets.
