Come to the construction site and try your hand at operating the big machines with the help of amazing pop-ups, pull-out play pieces, and plenty more.

When is a pop-up book not a pop-up book? When it’s also a play space, promising hours of fun! Master paper engineer Robert Crowther has outdone himself with this celebration of captivating machines, each commanding its own space: a dump truck, bulldozer, tractor, forklift, and tower crane. Included on each spread:
* One giant pop-up machine with movable parts (and some smaller machines, too)
* A fascinating description of what the machine is and what it can do
* A fact file of cool details such as measurements and weights
* A pouch containing pull-out, easy-to-construct items such as boxes and bricks
* Tips on how to work the big machine — and get busy playing! (Sound effects to be happily provided by users.)
