Using the simple and direct instructions, kids can build each machine in minutes. The projects include: incline planes, levers, wheels and axles, gears (spur, compound, rack and pinion, and planetary), cams, cranks, pulleys, ratchets, and springs. Includes timelines detailing the history of each machine.  Hands-on, interactive, and engaging, this kit will bring out the DIY and inventor spirit in every child. Launch date: October 2011.
