Just for fun:Do you believe in Ghost?
Ouija Board:

Science has it own explanation to it called as <a href="https://en.wikipedia.org/wiki/Ideomotor_phenomenon" target="_blank" rel="nofollow noopener noreferrer">Ideomotor Phenomenon</a> which explains that the user himself move it and the messages ostensibly spelled out by spirits were similar to whatever was going through the minds of the users, But i do have my personal experience with it where two of my friends are operating it ,and it is spelling out answer to the questions which i was even thinking in my minds, Nobody except me know what was going in my mind.
That's was mine experience ,Do you have any? My friends and cousin's used it a lot, They also believe in It.
