The Way Toys Work: The Science Behind the Magic 8 Ball, Etch A Sketch, Boomerang, and More
By Ed Sobey and Woody Sobey
Ed Sobey and Woody Sobey love toys and like to know how they work. Ed founded the National Toy Hall of Fame and cofounded Kids Invent Toys at California State University, Fresno. Woody is the state coordinator for Invent Idaho and director of education for the Discovery Center of Idaho. It must be great to make a career studying and inventing toys.
Every boy I’ve every known has tried to take toys apart to find out how they work. Well, Ed and Woody have taken apart all these toys, figured out how they work, and even put them back together. Toys may appear to be magical, but they really work on scientific principles. Once we see how they work, they may lose part of their mystique but we have learned a lot. Take the Wiffle ball for example. Originally, inventor David N. Mullany wanted to help his son throw curves without hurting his arm. The asymmetric forces created by slots in the ball cause the ball to spin, thus to curve. Air flows over one side differently than over the other side. Beyond that, there are principles to explain the phenomenon that have something to do with why airplanes lift. Cool. And speaking of asymmetry, that’s the main reason a boomerang comes back.
At the beginning of the book, the authors give guidelines for Reverse Engineering, what I would call taking apart the toys to see what’s inside. Of course, you will need proper tools, some safety rules, stuff to take apart, and curiosity. They also give some advice on building your own versions of toys and maybe looking at patents to find even more information on a favorite. After the introduction, the book lists toys alphabetically giving the history, a summary of how they work, suggestions for building your own, and related scientific experiments. There are resources for further investigation listed in the chapters and at the end of the book.
Children of all ages will enjoy this book.
