I really enjoyed this interactive book as a kid. An engrossing way to pass those hours in the backseat driving to Florida every Christmas. (Way before I started to get carsick riding in the backseat.) Then, as now, I loved the fun, funny and old-timey photos. But I never, not once, did any of the experiments. And, although I enjoyed the trip down memory lane, rereading it now, the book seems very wordy and complex (that is, boring) for a kids book.
