Behind the Science of Fireworks: What Makes Our Favorite Fourth of July Tradition So Spectacular

Fireworks are a favorite part of celebrating the Fourth of July, and there’s a lot of science behind their creation. According to Paul Smith, director of lecture demonstrations in the Department of Chemistry at Purdue University, fireworks are a combustion reaction that involves oxygen and other fuels. This reaction produces light, sound, and propels objects through the air.

Smith has over 30 years of experience working with pyrotechnics and explains that the colors in fireworks come from specific elements used in the fireworks. For example, strontium creates red, barium creates green, copper creates blue, calcium creates orange-red, and sodium creates yellow.

To create a successful fireworks show, those who work with shells carefully select different components to ensure that the final product is visually stunning once ignited. The combination of planning and scientific knowledge results in a sensory experience on Independence Day that includes vibrant lights, loud sounds, drifting smoke, and pressure waves that can be felt against the body.
