If I thought Steve Spangler hit a home run with "Naked Eggs and Flying Potatoes," then I must say this work is a Grand Slam! It is a marvelous companion volume to his other book, but it is also a wonderful edition on its own. The text is easy to understand, and children can follow the directions with minimal supervision. It gives them a great sense of accomplishment to be able to say they did it themselves. The pictures are vivid and entertaining, and the actual experiments are lots of fun in addition to being invaluable teaching moments. I have this paperbound tome, and I am eagerly anticipating the iTunes version as well. I would highly recommend this book to teachers, parents, those interested in easy science demonstrations, and the fine folks who are still children at heart - it's fun for everyone!
