The Ultimate Book of Saturday Science – The Very Best Backyard Science Experiments You Can Do Yourself

"This is the most extensive collection of project ideas at this level that I know of. Downie gives better 'how to' explanations and takes the ideas further than most other books of this kind. The Ultimate Book of Saturday Science is a true omnibus."--David Willey, University of Pittsburgh at Johnstown

"The projects in this book are interesting and thought provoking, and some are quite creative and unique. Educators can use the projects to enhance their teaching, and hobbyists will also enjoy them."--Kenneth G. Libbrecht, California Institute of Technology
