On the Fourth of July, fireworks displays are a beloved tradition that combine science and art to create a sensory experience unlike any other. According to Paul Smith, director of lecture demonstrations in the Department of Chemistry at Purdue University, fireworks are combustion reactions that involve oxygen and fuels to produce light, sound, and propel objects through the air.
Smith, who has over 30 years of experience working with pyrotechnics, explains how the colors in fireworks come from different elements used in their composition. For example, strontium creates red lights, barium produces green hues, copper results in blue flames, calcium creates orange-red tones, and sodium produces yellow explosions.
Creating a fireworks show requires careful planning and scientific knowledge to ensure that each component performs as intended when ignited. Those involved in creating fireworks shells must select specific components to achieve the desired visual effects and sounds. From vibrant colors to booming sounds and drifting smoke, fireworks displays are a true feast for the senses on Independence Day.
