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.

Fireworks, also known as fireworks, fireworks and firecrackers, were invented earlier by the working people in China and are often used in grand ceremonies or performances. However, the only event in modern China and even the world that can set off fireworks on the same day is regarded as New Year's Eve. 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.
In the process of making fireworks, some luminescent agents and chromophores are added to make the fireworks emit colorful colors. The luminescent agent is powder of metallic magnesium or metallic aluminum. These metals give off incandescent light when they burn. Chromophores are actually just some metal compounds. 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. In order to protect the environment, many fireworks and firecrackers do not use substances containing heavy metals and sulfur elements, thus reducing the production of sulfur dioxide and other sulfides. Secondly, the consumption of metal powder is reduced, and organic matter is basically used as combustible, thus reducing the inhalable particulate matter produced after the combustion of metal powder. The third is to change the oxygen balance and combustion temperature of the system by changing the amount of oxidant and combustible, and control the combustion reaction.
