A spirit board, often known as a Ouija board, is a flat board marked with letters, numbers, and other symbols. Users place a planchette, a small heart-shaped piece, on the board and lightly touch it with their fingers. The idea is that spirits can communicate by moving the planchette to spell out messages. Spirit boards have been used for centuries in various cultures for divination and spiritual communication. They gained popularity in the 19th century during the Spiritualism movement, where people sought to connect with the deceased. While many view them as a fun game, others take them seriously as a tool for contacting the spirit world.
