I recently discovered James Randi on YouTube. He is an ex-conjurer and "professional sceptic" who debunks so-called claims of psychic powers. Indeed, he's put up a prize of one million dollars to anyone who can prove these powers under scientific conditions. He's still got the million dollars. He debunked Yuri Geller and even demonstrated how spoon bending etc. were done. Geller tried to sue him and lost.
