    The gift that inspires.


    A great way to get your kids or grandchildren interested in the principles of physics, engineering, and math.


    Like "The Crank", this spiral toy is hand-powered but twice the fun.  Marbles go up the center  elevator then race down both sides.


    Dimensions:  3 1/2"D, 8 1/2" W, 16" H


    The toy is made from Vermont Maple and comes with 32 self contained marbles .
