TUCSON - Behind the big boom, there's an exact science for those fireworks displays.

Different elements are in play to light up the night skies. Here's a quick chemistry lesson.

Compounds of strontium are the reason for the radiant red fireworks. Strontium also helps produce vivid violets, teaming up with copper to do so.

Greens glow thanks to compounds of barium or boron. Copper, a common element in Arizona, plays a role in beautiful blue. Orange fireworks are created with the element calcium.

Silver shimmers in the night sky, due to superheating the elements of magnesium or aluminum. Whimsical whites also get their fantastic finish from these two elements. Titanium can also create white fireworks.

Finally, combining calcium with barium produces yellow fireworks. Other times, yellow colors come from components of sodium.
