A substantially spherical ball to be used in a cursor controlling mouse. The mouse ball is formed from a composition of silicone having zirconium dust dispersed uniformly throughout. The zirconium provides the added weight necessary to keep the ball rolling on a working surface, but is not sufficiently conductive to short electrical components in mouse. The uniform composition provides for the mouse ball to have its gravitional center coincident with its geometric center to inhibit cursor jitter when the mouse is manually moved.
