Paint The Fireworks

OK, I know it's not really painting. but couldn't think of a good title..

Did you know that the fireworks were invented in China about 2,000 years ago? Did you know that a monk named Li Tian invented the fire crackers 1,000 years ago?

History of the Fireworks

How are fireworks are colored? Well, it's all bout chemistry ;-) From the "How Stuff Works?" website.

By the way, I found this site helpful in the past. It's an excellent site. I am surprised they changed the layout though, they had a really nice layout previously.
