This volume of the “Chemtastrophe!” series shows how most of the medical and personal care items we use every day, from aspirin to toothpaste to deodorant, were developed using chemistry. A brief overview of chemistry sets the stage for this slim volume. “Fun Facts” sidebars reveal chemistry-related tidbits such as the fact that talc is the world’s softest known substance. Inset “How We Know” sections offer historical information such as why the Federal Food, Drug, and Cosmetic Act was written. Additionally, the scientific method is outlined. Each book in the series provides two simple experiments for readers to try.
