🎆 Fireworks — Chemistry of Colour
Launch fireworks and discover the chemistry of colour! Different metal salts burn in different colours — strontium for red, copper for blue, sodium for yellow. Each firework is a tiny chemistry experiment in the sky.
🔬 What It Demonstrates
When metal atoms are heated, electrons jump to higher energy levels and emit light when they fall back. Each element emits specific colours: strontium = red, barium = green, copper = blue. This is the same physics used in atomic emission spectroscopy.
🎮 How to Use
Click anywhere to launch a firework. Choose different chemical colours in the panel. Adjust launch angle, burst size, and sparkle duration to create your own display!
💡 Did You Know?
Blue fireworks are the hardest colour to make. Copper compounds burn blue, but copper chloride becomes unstable at high temperatures and turns green. Fireworks chemists spent decades perfecting stable blue — it was solved only in the 1990s.
