Filled with photos and illustrations, 15 Dangerously Mad Projects for the Evil Genius includes step-by-step directions, as well as a construction primer for those who are new to electronics projects.

Whether playing at defending their own castle or simply chucking pumpkins over a fence, wannabe marauders and tinkerers will become fast acquainted with Ludgar, the War Wolf, Ill Neighbor, Cabulus, and the Wild Donkey--ancient artillery devices known commonly as catapults.

Join a team of top mechanical minds - structural engineers, architects and heavy construction experts - as they battle the clock (and each other) to build the world's largest trebuchet in only seven days. In the spirit of Discovery's hit shows Monster Garage and BIG!, follow the group of seven builders through the actual planning, construction and test-firing of their gigantic, 40-foot slingshot. Then, meet the guys on the launch pad and watch as they try to catapult themselves into the history books by launching a flaming car 500 feet into the air. Whatever happens, you can bet the landing will be explosive.
