The Works is a kids science and tech museum in Bloomington, Minnesota, just a few miles from where I live in Minneapolis. Today, they had this cool chart up on their Facebook page, explaining which chemicals produce the colors you see in fireworks. How cool is that? Tomorrow, when the rockets glare red, you'll know that's actually strontium carbonate.
