A paper pop-up book that is an imaginative leap from anything you've seen before! Calling all boys and girls: the most amazing show on earth is about to begin. You'll hardly believe it even when you see it-six awesome pop-up acts presented by "invisible bugs." Move a tag and you'll thrill with excitement as fleas fly through the air on a pop-up trapeze. Pull the tab at the top of the page and a hidden wire will make you believe these tiny insects are taking the dive of death in to an impossibly small pool below. Want to see the world's scariest light show? Shine your flashlight behind a large pop-up screen and it will illuminate dozens of gruesome mites.Plus: a host of mechanisms let you control the juggling genius, fire the fleas from a pop-up cannon, and more! Watch, wonder, and learn a load about science as each performance illustrates the star's skill...plus principles such as gravity, force and movement, speed and momentum, light, balance, and friction.
