Gunpowder (video link)

Description:

In the mid-ninth century, Chinese chemists, hard at work on an immortality potion, instead invented gunpowder. They soon found that this highly inflammable powder was far from an elixir of life -- they put it to use in bombs against Mongol invaders, and the rest was history. This video details how gunpowder has caused devastation around the world, despite the incandescent beauty of fireworks. Ask yourself, how did such a discovery radically change society and warfare as it spread to areas outside of China?
