🎆 How do fireworks and firework displays work?

Fireworks are like magic lights in the sky! 🎇 They are made of special powders that make bright colors when they burn. A little fire makes them fly up high, and then they explode with beautiful sparkles and booms! 💥

People use fireworks to celebrate big days, like New Year's Eve or Independence Day. They light them carefully so everyone stays safe.

Fireworks are made of gunpowder and chemicals that create colors when they burn. 🧪 Here’s how they work:

• A fuse is lit, which starts a small explosion to launch the firework into the sky.
• Inside, a time-delay fuse burns until the firework reaches the right height.
• Then, the main charge explodes, scattering colorful sparks!

Different metals make different colors—copper for blue, strontium for red, and magnesium for white! 🌈

The Science Behind Fireworks

Fireworks are pyrotechnic devices designed for entertainment. Here’s a detailed breakdown:

1. Launch: A mortar tube propels the firework using a lifting charge (black powder).
2. Timing: A time-delay fuse ensures the explosion happens at the right altitude.
3. Explosion: The bursting charge ignites stars (small pellets with metal salts) that create colors.

Color Chemistry:
- Red: Strontium compounds
- Blue: Copper compounds
- Green: Barium compounds

Modern displays use computer systems for precise timing and synchronization with music! 🎵
