Fireworks are one of the things us people love and admire, but how do they work? How do these beautiful colors combine and make something so amazing? Well, fireworks were first invented during the Tang Dynasty in the 7th century China, it was used in many festivals and it became part of the Chinese culture. Since then fireworks had been carried out to many countries, it’s colors making a huge impact to the world.
The first firework was made by a Chinese monk, Li Tan, who took a piece of bamboo and put gunpowder inside of it. He put fire to the gunpowder and it made a loud enough sound to scare the evil spirts away. The fireworks these days isn’t different, we use a shell, explosive, and a fuse. The colors were add when they used steel and charcoal making the colors yellow and orange. After a while they started experimenting with other metals that absorb energy. Strontium compounds make red, barium makes green and copper makes blue. When you combine this it’ll show a variety of colors that will light up the night sky.
These fireworks work in a way that is very simple, they load the firework into a tube/cannon and carefully trying not to ignite the gunpowder. Gunpowder is packed on a bottom and when ignited, the gunpowder shoots out a package. The package contains a shell that has gunpowder that has these little shards of metal embedded in them. The little shards of metal is called “stars” and this is what gives it color.
Even though the fireworks are sometimes dangerous it’s worth watching such beautiful colors in the sky. Fireworks were first meant to scare away evil spirts but it soon evolved into something pretty that people can enjoy. People always wait for the fireworks to go up and paint our sky with colors, I can’t wait to see the fireworks on July 4th.
