The ouija also known as a spirit board or talking board, is a flat board marked with the letters of the alphabet, the numbers 0–9, the words "yes", "no", "hello" (occasionally), and "goodbye", along with various symbols and graphics. It uses a small heart-shaped piece of wood or plastic called a planchette. Participants place their fingers on the planchette, and it is moved about the board to spell out words. "Ouija" is a trademark of Hasbro, Inc., but is often used generically to refer to any talking board.Is the Ouija board dangerous? Most paranormal researchers advise against the casual use of the Ouija board, suggesting that it can be a doorway to unknown dimensions. Religious believers worry that it may result in a form of possession. Skeptics may dismiss the question, say you are opening yourself to manipulation by other people, or exaggerating the fears deep inside you.
