Skeptics know Ouija boards aren’t real. The “spirit” can’t answer your questions. Any movement of the “planchette” is done by the people asking the questions. And it’s all in your head.
But there are people who think otherwise, in part because of viral videos showing the board’s supposed psychic powers.
YouTuber Stephen Woodford addresses all of those concerns in this video.

He offers some excellent suggestions for how we can tell the board has no powers.
If only the gullible believers would ever give them a shot.
