Build a material lift, a stationary bike, a crane bridge, a blender, a construction crane, and a windmill, then see how pulley drives transfer force with reduced friction and boost force or speed. Easy-to-follow building instructions guide the way as kids move from one working model to the next, testing mechanical advantage with real, functioning machines.
