Fireworks are beautiful displays we often see lighting up the sky on special occasions.
They were first made in China about 2,000 years ago and were used to scare away bad spirits.
Every bright and colorful firework begins as a simple cardboard tube filled with special materials.
First, there’s a fuse on the outside that is lit to get the firework started.
Once lit, the fuse burns down into the tube and hits a charge called the lift charge, which bursts and sends the firework high in the sky.
Then, the fuse reaches the main part of the firework, called the stars, and that’s where the magic happens.
Stars are small balls made of some chemicals that burn in bright and dazzling colors.
Depending on what chemicals the stars contain, they can burn in reds, blues, greens, purples, and many other colors.
So, the next time you’re watching a firework display, remember all the amazing science that’s happening right before your eyes!
