With this book, you can build 10 interactive models, creating large-scale toy machines with moving parts from only paper. All parts are provided, printed on large heavy-stock paper with perforations to make it easy to pop out the detailed pieces before gluing them together.

Each project includes a history of the machine followed by color-coded, numbered instructions on how to assemble the model. In order of difficulty, they include a steamboat, dirigible, ladder truck, haul truck, locomotive, excavator, concrete mixer, front loader, helicopter and space shuttle. Each takes from 45 minutes to three hours to complete. An irresistible family activity.

Softcover, 11" × 17", 46 pages of instructions plus 41 sheets of pop-out parts, 2015.
