Fireworks work through a series of chemical reactions that produce light, heat, and sound. The primary reaction involved is combustion, where fuel, such as charcoal or sulfur, reacts with oxygen from the air to release energy in the form of heat and light. This energy is what powers the explosion and the brightness of the firework. The different colors produced in fireworks come from the metal salts used in the mixture. For example, strontium salts create red colors, copper compounds create blue, and barium compounds create green. These metals release energy when heated, causing the colors to appear. Additionally, oxidation-reduction reactions occur when oxidizers like potassium nitrate provide oxygen to the fuel, allowing the reaction to take place. Some fireworks also use explosive reactions, like the ones in black powder, which create a loud bang and forceful explosion by rapidly releasing gases. These chemical reactions work together to produce the dazzling visual and auditory effects we enjoy during fireworks displays.
