ESP cards were developed and introduced by Dr. J. B. Rhine of Duke University for the purpose of testing for Extrasensory Perception. They consist of five basic symbols: Circle, Cross, Wavy Lines, Square, and Star. It is very easy to remember these symbols by using a quick and easy numbering system. A circle is one continuous line. A cross is two lines. There are three wavy lines in the third symbol. A square has four lines. The star used has five points. This deck consists of twenty-five cards, five cards of each design. There are many effects that can be performed with this deck of cards. For example:
