Abstract
A selector apparatus is disclosed herein for randomly selecting a predetermined quantity of numbered spheres or balls which includes a cylindrical housing having an internal storage compartment occupied by the numbered spheres in a liquid solution such as oil. The compartment is connected to a display chamber by a funnel whereby the numbered spheres are introduced to the display chamber in a randomly selected order. At least the display chamber is defined by a transparent window permitting visual observation of the selected spheres. The storage compartment is of greater area than the display chamber and a support base or chain device may support the apparatus.
