The Motorboat Book: Build & Launch 20 Jet Boats, Paddle-Wheelers, Electric Submarines & More (Science in Motion)

I've been fooling around with electrical stuff since I was a kid. This book is not only fun to read but it answered many questions and provided me with lots of new info to work with. Highly recommended.Fred

This is exacting the kind of activities that activates thinking and creativity. I'm impressed to see that Ed has, once again, opened up the "fun for all box" and invited us to play! I will continue to look to invention as great social/cultural activity for my students. It is also access for younger learners and yet has real grit for older learners as well.
