In addition to the boatbuilding activities, author Ed Sobey includes instructions on how to build an “ocean” to test the boats, as well as accessories such as four different water pumps, waterproof battery and motor cases, and a working foghorn. Most of the boats are built from recycled and easy-to-find materials, but an appendix lists local and online sources for wire, plastic propellers, small motors, and more. Educators will appreciate the Meeting Science Standards summary at the end of the book.
Ed Sobey is the author of Unscrewed, The Way Toys Work, and The Way Kitchens Work, and many other titles.
