A Ouija board, also known as a spirit board or talking board, is a flat board marked with the letters of the alphabet, the numbers 0-9, and the words “yes” and “no”. It is used during sances to facilitate communication with the dead. Participants place their fingers on a planchette, a small heart-shaped piece of wood or plastic, and ask questions. The planchette is then said to move around the board, spelling out answers to the questions.
Ouija boards have been around for centuries, and their popularity has waxed and waned over time. Today, they are still used by some people who believe that they can communicate with the dead. However, there is no scientific evidence to support this claim. Most scientists believe that the movement of the planchette is caused by the unconscious movement of the participants’ fingers.
