Fireworks

Fireworks are a special type of explosive that is set off in the night sky, known for its colorful lights and dazzling effects. It is an art performance that combines chemicals and explosive materials such as gunpowder to cause explosions and flames by igniting a fuse.

Fireworks usually consist of several main parts. The first is the shell of the firework, which is a container made of paper, filled with gunpowder and chemical fluorescent agents of various colors. When the fuse is ignited, the gunpowder explodes and sprays the chemical fluorescent agent into the air.

The explosion of fireworks produces colorful lights and shapes. Different chemical fluorescent agents can produce different colors, such as red, green, blue, yellow, and purple. By controlling the combination and spraying method of gunpowder, various shapes can be formed, such as flowers, stars, hearts, willow leaves, and rotating patterns.
