As your friends and family are "oooh-ing" and "ahhh-ing" over fireworks on the Fourth of July, you can pipe in: "Red is likely produced by strontium nitrate" and "blue is the hardest color to produce pyrotechnically."
That, is of course, if you watch a new video from the American Chemical Society.
As part of the group's "Reactions" series, the video follows a Washington College chemistry professor as he takes you through both the chemical processes that produce the vibrant hues and the physical process that launches the brilliant balls of light.
Armed with this information, you can declare your independence from ignorance this Fourth and illuminate your companions with your knowledge. Either that, or you'll annoy the heck out of them and they'll never take you to another fireworks display again.
