Fireworks are like little chemical explosions in the sky. When they go off, tiny bits of chemicals inside them get super hot and start to glow. Different colors come from different types of chemicals, red might be from strontium, blue from copper, and green from barium. It’s like when you mix paint, but instead of paints, fireworks use special powders that make light.
Examples
- A red firework might have strontium compounds inside it, like Sr(NO₃)₂.
- Blue fireworks often use copper chloride to create their bright color.
- Green fireworks come from barium salts that glow when heated.
