Unraveling the Science of Fireworks: The Chemistry Behind Independence Day Displays

Fireworks displays on the Fourth of July involve a complex chemistry reaction that produces light, sound, and propulsion. Paul Smith, director of lecture demonstrations in the Department of Chemistry at Purdue University, explains that fireworks are a combustion reaction involving oxygen and other fuels. The different colors of fireworks are produced by the elements used in them, such as strontium for red, barium for green, copper for blue, calcium for orange, and sodium for yellow.

Creating a fireworks show requires a deep understanding of how the chemicals will react and perform in the air. Those who create fireworks carefully combine different components to achieve a variety of effects when ignited and in flight. The science behind fireworks displays is ultimately what makes them such a sensory experience on Independence Day. This includes not only the visual display but also the sound produced by the fireworks, the smoke that accompanies them, and even the pressure wave created by the loud noises that can be felt against the body.
