HOW FIREWORKS WORK - AN INTRODUCTION TO FIREWORK SCIENCE

http://www.explainthatstuff.com/howfireworkswork.html

An easy-to-understand introduction to the science of fireworks: how do they get into the sky and where do all the different colours come from?

It's just as well fireworks were invented in ancient times, because such an outrageous invention surely wouldn't be allowed in our risk-averse society today. Just imagine if fireworks didn't exist and someone suddenly suggested the idea of allowing people to fire lots of explosives into the air! Fortunately, that's not the case and we can still enjoy the dazzling magic of these psychedelic aerial displays every time we feel like a joyous outdoor celebration.

Fireworks teach us some interesting physics and chemistry, this site takes a closer look at what they are and how they work!
