Colorful fireworks: The color of a fireworks burst is created by adding metallic compounds that flame with a known color to the stars within a fireworks shell. This photo shows fireworks bursts with a variety of color.
Lights, Colors, Sounds, Shapes and Surprises!
Why do fireworks displays attract so many people? There are many answers to this question, but most people simply enjoy the bright explosions of light, color and sound. Others enjoy being surprised by the shape and color of the fireworks bursts. These shapes and colors do not happen by chance. They are deliberately produced by a careful combination of art, chemistry, physics and math!
Aerial fireworks display: The vibrant colors in a fireworks display are made possible by minerals. Each color streak in the display above is formed by a burning particle as it travels through the air. Metal salts in the burning particles absorb heat energy and release it in the form of colored light.
