Accessibility Statement


More than just a collection of projects, each toy in this book is designed to demonstrate principles of science, technology, engineering or math. Most importantly, it illustrates creative thinking and problem solving – instead of giving precise instructions for making the toys, Gilsdorf guides the reader through the stages of taking a design from idea to working toy.

Measured drawings and assembly diagrams assist you in building the toys yourself. With a range of designs that includes catapults, candy dispensers and mechanical puzzles, the toys in this book are sure to be a hit with the recipients and inspiration for inventions of your own. Softcover, 7" × 9", 184 pages, 2018.
