How Do Fireworks Actually Work ? [VIDEO]

We line up in droves every July 4'th and ohh and Ahh at the spectacle and booms of fireworks. It's not magic it's science, and very dangerous for those lighting them off.

We all have a basic knowledge of how they work, and what they are made of, but I came across this dorky tutorial to break it down for us. I found this really interesting, even though sometimes Science can get a little boring.

Be safe this July 4'th leave the big booms to the experts, and just lean back look to the skies and mutter, I know how they make them do that!
