From the sizzle of the fuse to the boom and burst of colors, this video brings you all of the exciting sights and sounds of Fourth of July fireworks, plus a little chemical knowhow. The video features John A. Conkling, Ph.D., who literally wrote the book on fireworks — he is the author of The Chemistry of Pyrotechnics, Basic Principles and Theory. Conkling shows how the familiar rockets and other neat products that light up the night sky all represent chemistry in action.
