The screw, another of the simple machines, converts a circular motion (the turning of the screw) into a linear motion. It also lets you amplify the force a great deal, since turning the screw only moves the end of the screw a small amount. This classic wooden model offers children a basic concept of the laws of physics. Desktop sized.
