How do fireworks get their colors? Every color is a glowing metal, and blue is the hardest one to make.

Each shell is packed with pellets called stars, mixed with metal salts. Heat kicks electrons up, and when they fall back, they release light: strontium red, barium green, copper blue. But copper's blue comes from copper chloride, which only survives in a narrow heat window. Too hot, and the blue washes out. So a deep blue firework means the chemist got the heat just right.

Every firework is a chemistry test, written in the sky.

Send this to a friend who thinks green crackers glow green.
