How do fireworks work?

There's only a couple of days until we gaze at explosive eliminations, jaws agape while vocalizing ooos and aaahs rivaling those coming out of a streetwalker's boudoir. But what makes them work? The fireworks, that is.

Those colorful detonations are chemical-laced bombs, carefully configured for explosive effect, and launched with lift charges from mortars, with fuses lit by brave souls wearing fire suits. Sometimes, they're lit by computers and remote controls.

We got to see 10,000 of these bombs lit, fired and launched, up close and personal last year. It was unforgettable.
