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.
