Chemistry on Display

One of the things I most look forward to on Independence Day is watching the city fireworks display. Everyone in the crowd is enchanted by the bright colors and booming explosions. Did you know that the different varieties of firework shells have names? Some of my favorites are the glitter palm, the dahlia and the peony. The different shapes and hues are designed by pyrotechnicians, who apply their knowledge of physics and chemistry to bring the night sky to life. See if you can identify the different shell shapes at pbs.org/wgbh/nova/fireworks/gallery.html.

Metal salts create the different colored explosions. For example, calcium salts emit orange, and copper compounds burn blue. These salts are mixed with other chemicals and formed into small balls called stars. The stars are arranged inside the shell to produce the different designs.
