While some people claim to communicate with spirit entities through Ouija boards, scientists don't believe that the boards really work. They explain that the Ouija board functions due to the ideomotor effect, in which the body makes movements unconsciously.
The Ouija board primarily consists of a flat board and a pointer that is used as a divination tool. Users touch their fingertips to the pointer and wait until it moves, spelling out words and messages. While many people consider the Ouija board to be a harmless parlor game, some Christian denominations believe that its use can lead to demonic possession. The Ouija board was patented as the "Ouija Egyptian Luck-Board" by attorney Elijah Bond in 1891.
