The Mill model with an open mechanism and a secret drawer is a challenging model to keep you entertained for hours. Wind transforms into kinetic energy through the rotation of the blades. This is how a real mill works. You, on the other hand will power your own Mill. Its blades turn according to your desire; all it takes is to turn a special key. A few turns of the key activates the rubber band drive of your Mill! This sets in motion all the cogs, among which there is a flywheel, and a real planetary gear. Ages 14+.
