Fireworks are also called fireworks, fireworks, fireworks and firecrackers. According to "China Fireworks and Firecrackers Standard-Safety and Quality", fireworks and firecrackers are defined as entertainment products that use pyrotechnics as raw materials and produce acousto-optic colors.

Fireworks are actually similar in structure to firecrackers, and they all contain black powder and medicine. In order to achieve good performance, fireworks and fireworks bombs are filled with a lot of gunpowder for launching and explosion. For example, a fireworks bomb with a diameter of 20 cm will explode only when it rises to a height of about 200 meters after launch, and the radius covered by these points can be about 80 meters.

Metal compounds contain metal ions. When these metal ions react violently with oxygen molecules, you will see the compound burn and emit a unique flame color.
