How It's Made: Fireworks?

Fireworks are like exploding balloons that light up the sky with colors and shapes.

Inside a firework is a special kind of powder, called gunpowder. When you light it, it starts to burn really fast, like when you strike a match but much quicker! This burning makes a lot of heat and gas, which pushes against the outside of the firework, making it burst open.

Some fireworks have little pieces inside called stars. These are tiny bits of powder mixed with special chemicals that make colors when they burn. Different chemicals give different colors, like red, blue, or green. It’s like mixing food coloring in water, but instead of making a pretty drink, you’re making a pretty explosion!

When the firework bursts, all these stars fly out and light up the sky. It's like throwing confetti that also shines bright!
