Through a series of carefully-devised experiments and conversations about the experiments, he leads the boys to an understanding of some of the basic principles of chemistry. Excellent as a follow-on to "The Story Book of Science" and "The Secret of Everyday Things" by the same author. Suitable for ages 11 and up.
