The Chemistry of Fireworks - Reactions This video explains the chemical reactions that occur inside of a firework that creates explosions of beautiful colors. The oxidizers, fuels like sulfur are products, substances that provide color, and the source of energy is fire. The reaction is colorful and powerful, this is the firework. In the experiment portion, he adds potassium perchlorate + red gum to make the firework explosion with fire as his energy source.
The Chemistry of Firework Colors: Creating firework colors is a complex endeavor, requiring considerable art and application of physical science. Excluding propellants or special effects, the points of light ejected from fireworks, termed 'stars', generally require an oxygen-producer, fuel, binder (to keep everything where it needs to be), and color producer. There are two main mechanisms of color production in fireworks, incandescence and luminescence.
