Do you remember watching with amazement when those cartoon heroes constructed machines to catch someone or start something? Those very complicated Rube Goldberg-like ones with knives, toasters, anvils etc? Or did you ever wonder how it would feel to construct a mouse-powered device to cook some eggs and launch a rocket? Well, the answer is here! Build monkey or mouse-powered machines, use lasers and fire fireworks, start fires using a bowling ball and flint, throw things with anti gravity platforms or a jack-in-the-box or crack open an aquarium with a cat, mouse, alligator, cannon, cheese and more!
