Each of the ten machine projects are printed on sturdy card stock in full color with detailed step-by-step instructions, so all kids need to do is pop out, fold, and glue to create their own working colossal machines. What are the machines? Kids will make a steamship, dirigible, ladder truck, dump truck, locomotive, excavator, concrete mixed, front loader, Chinook helicopter, and space shuttle. Don't know what a Chinook is? That’s okay, because the book also explains the inner workings of these colossal machines: how they work, who invented them, and what they’re used for. Perfect for any child who loves big machines or who likes to build paper toys.
