Starting with a mixture of iron filings and sulphur, Uncle Paul awakens in his young nephews an eagerness to learn more about the properties of the elements. Through a series of carefullydevised experiments and conversations about the experiments, he leads the boys to an understanding of some of the basic principles of chemistry. Excellent as a followon to 'The Story Book of Science' and 'The Secret of Everyday Things' by the same author. Suitable for ages 11 and up.
