Query: Humbug

This Board dose not work. I dare anyone who believes in this board to try it with a blindfold on. ghosts (if real) don't use this or any other board to talk to the living. Penn and Teller debunked this board on their showtime show. buyer beware this board is what Houdini would call "Humbug"
