What Is A Firework?

Have you ever watched the sky explode in colours on Bonfire Night or New Year's Eve? That’s all thanks to fireworks! But what is a firework, really?

A firework is like a mini rocket filled with powder, colours, and really cool science. Inside, there’s something called gunpowder that helps it shoot into the sky. Once it's up high, it bursts open, and boom - you get a colourful explosion!

The colours come from different chemicals. Red comes from strontium, green from barium, and blue from copper. Each chemical burns a different colour when it gets really hot.

The patterns you see - like stars or rings - are made by the way the stuff inside the firework is arranged. It’s like a tiny puzzle with a super cool ending!

So next time you see fireworks, remember: it’s not just magic. It’s science lighting up the sky!
