Abstract
IN his book on “Gyrostatics and Rotational Motion”, the late Prof. Andrew Gray explained how a top can be made to move along two parallel horizontal wires when they are rocked so as to change the point of support from one wire to the other. A few years ago, I discovered that a spinning top will automatically walk down two parallel wires arranged as an inclined plane.
