The 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, the words “yes,” “no,” “hello,” and “goodbye,” and various symbols and graphics. It is used as a tool for communicating with the spirit world. The origins of the Ouija board are unclear, but it was first patented and sold as a commercial product in 1891 by the Kennard Novelty Company.

The Ouija board became popular in the late 19th and early 20th centuries as a tool for spiritualism and mediumship. Its use has also been associated with the occult and paranormal activity. Despite its controversial reputation, the Ouija board remains a popular tool for communicating with the spirit world in modern times.
