Ouija Board

The Ouija board began as a novelty game which could magically identify answers to questions by using a planchette which seemingly moved on its own. The board appeared to suddenly appear into game culture, but in reality a prototype was previously used by individuals attempting seances or communicate with spirits. Some psychologists believe there to be a link between the known and unknown through the board. Once Hollywood began using the board in movies, they became a taboo overnight.

In reality, the movement of the planchette is determined by the users' slight unconscious movement of their fingers. Powerful messages from the Ouija board on impressionable people leads to extreme belief in the power of the board. Psychics, mediums, and everyday believers continue to use these boards and feel that they do in fact contact the dead.
