Have you ever wondered how certain fireworks can make awesome displays of color and explosion?  There’s actually quite a bit of science behind it.  Basically, the fireworks designers have to figure out how to slow down the chemical reaction and explosion to make them look better.  And the light comes from them cooling down.  I won’t bore you with the technical details.  You can visit this site to get a more detailed explanation.

I’ve dreamed of a job designing fireworks, and I still think it would be fun, but I’d rather learn by trial and experiment rather than all the scientific formulations and stuff…  🙂
