From the sizzle of the fuse to the boom and burst of colors ––a new American Chemical Society (ACS) video brings you all of the exciting sights and sounds of Fourth of July fireworks. The Chemistry of Fireworks, part of the ACS Holiday Video Series, ...illustrates in brilliant high-definition detail how the familiar rockets and other neat products that light up the night sky all represent chemistry in action. The video, released today, features a demonstration by fireworks expert John A. Conkling, Ph.D., Washington College, Chestertown, Md., author of The Chemistry of Pyrotechnics, Basic Principles and Theory. The video was produced by the ACS Office of Public Affairs and takes a close look at the components of fireworks, including time fuses, fuel and bursting charges, and explains how the vibrant colors are generated.

The video gives step by step directions on how to make sidewalk chalk using plaster of paris, water, and powdered tempera paint. The instructor also explains the science behind the craft. Most kids think of solids turning to liquids and liquids to so...lids because of a temperature change. In this experiment, a chemical reaction causes the mixture to change from a liquid to a solid. As the chemical reaction occurs it also gives off heat which is called an exothermic reaction. This instructor makes a "holiday gift" with her sidewalk chalk, but this activity could be done any time of the year. Run time 04:20.

How can something submerged in water stay dry? When ordinary sand gets wet, the result is a clumpy mess. However, "Magic Sand" begins as normal looking sand, until it's coated with a substance that repels water. This special coating keeps the sand dr...y even after it has been dumped into a container of water. Build castles and other structures under the water, then simply pour the water off when you're finished and the sand is still dry. Students are going to like to watch this and learn how it is done.

This 4:26 long video shows how to combine sand with a water-resistant chemical you create a product that is easy for students to make and can result in exciting new art projects as well as science lessons on chemical reactions. Shows how this substan...ce attracts oil as well. Commercial starts at about three minutes so you might want to end the video at that time.
