Why does a stair runner run down the stairs? The stretched stair runner contracts, causing the rear section to swing forward, making it appear that the stair runner is somersaulting. This spring lets you perform lots of hands-on experiments on momentum, gravity and wave propagations. Read about it in the educational booklet that is included!
