Fireworks

Fireworks operate through an explosive chemical reaction involving gunpowder, which contains potassium nitrate and carbon. A fuse ignites the gunpowder, launching the firework and causing it to explode. Metal salts in the fireworks produce vibrant colors when ignited, such as green from copper sulphate, red from lithium carbonate, and yellow from sodium nitrate. These chemical reactions create the spectacular displays seen during celebrations.
