This work contains Science with the squishy bits left in. It's time to gear-up for some evil inventions. Dare you discover: the bottom-stabbing bike saddle? The head-chopping machine operated by a sheep? The terrible toilet snorkel? If you think you can stomach the sick side of science, then read on as we get to grips with gruesome gadgets and murderous machines that killed their inventors. With fantastic fact files, quirky quizzes and crazy cartoons, "Evil Inventions" is buzzing with brilliant brainwaves. Science has never been so horrible.
