Intended to arouse interest in science, this is the author's third book in the series. The experiments are relatively simple to perform. The explanations are adequate, but far from complete which, for an appetizer, is no fault. The author's bantering style comes across quite well, supported by the humorous illustrations. The organization is fairly relaxed, with occasional full introductions, one including information on lasers. Altogether, it is an enjoyable book for browsing, and the basic concepts become readily apparent.
