Mad Machines and Dotty Devices

Mess up your hair and work on your crazy laugh, it's time to bring out your inner mad scientist

From using a balloon to create a rocket, to powering bottles through the water with paddles, these tried and tested ideas will soon have you on your way to techno-wizardry. You'll also learn to spy on neighbors with a secret Spyscope, or look at your friends upside down with a pin-hole camera. All the projects use everyday materials, a brief fact file explains the science and technology, and there is extra information on nutty inventors and amazing machines.
