It’s the night tonight for fireworks and bonfires – bright coloured lights in a dark sky. The colours are made by chemistry. Metallic salts burn with different colours. If red is wanted, it needs strontium carbonate in a firework. Copper makes blue, and strontium and copper together make purple. Other metals include barium (for green), calcium (for orange) and sodium (for yellow). Children like fireworks but dogs do not like them.
