Fireworks are like mini-explosions that create dazzling displays of colors and sounds. They are made up of different parts that work together to create magic in the sky. Let's explore how they do it:
Fireworks have an outer shell made of paper or cardboard. It's like a protective cover that keeps everything inside safe.
There is a special fuse attached to the firework. When we light the fuse, it starts to burn slowly. Think of it like a little sparkler that sets off the firework.
The Lift Charge
Inside the firework, at the bottom, there is a small explosive called a lift charge. When the fuse burns down to the lift charge, it goes "boom!" and gives the firework a big push up into the sky.
Inside the firework shell, there are small compartments filled with tiny chemical pellets called stars. These stars are what create the beautiful colors we see in the sky. Each star has different chemicals inside that make it produce a specific color when they burn. Some chemicals make red, some make green, and others make blue. When the lift charge explodes, it lights up the stars.
The Burst Charge
As the firework goes up, it reaches a special part called the burst charge. It's a bigger explosion that sets off all the stars at once. This is when we see the firework burst open and create a bright and colorful explosion in the sky.
Sounds and Effects
Fireworks can also make cool sounds and effects. There are special compounds inside that burn quickly and create loud bangs or crackling noises. They add extra excitement to the show!
Remember, fireworks are made by experts who know how to handle them safely. It's important to only try to make your own fireworks or play with them with an adult. Fireworks should always be enjoyed from a safe distance to keep everyone happy and safe.
So the next time you watch fireworks, you'll know that they are like a combination of explosions, colorful stars, and special effects, all carefully designed to create a spectacular show in the sky!
