Why fireworks explode 800 feet in the air and form perfect shapes

Fireworks may look like simple explosions in the night sky, but the science behind them is surprisingly complex. Their origins date back more than 2,000 years to China, where early experiments with gunpowder eventually evolved into modern displays. Today’s fireworks rely on carefully engineered shells, chemical reactions, and precise fuses to launch explosions hundreds of feet into the air and create vivid colors. The physics behind the light, shapes, and timing involves everything from combustion chemistry to quantum mechanics.
