ABSTRACT
This paper describes a device, consisting of a central source and two widely separated detectors
with six switch settings each, that provides a simple gedanken demonstration of the non-classical
correlations that are the subject of Bell's theorem without relying on either statistical effects or the
occurrence of rare events. The mechanism underlying the operation of the device is revealed for
readers with a knowledge of quantum mechanics.
This paper appeared in Am.J.Phys. 72, 1303-7 (2004).

1. Introduction
This paper presents a gedanken experiment involving a source and two widely separated
detectors/observers that conveys the essence of the non-classical correlations that are the
subject of Bell's theorem [1] to a lay audience without relying on either statistical correlations or
the occurrence of rare events. The device on which this demonstration is based was suggested
by the work of David Mermin and Asher Peres (see Sec.4 for a more detailed statement of
