Well, Dusty, it doesn't really matter if you think dowsing is paranormal or not. It's not your million bucks that's on the line. Randi says it's bunk, all you have to do is prove him wrong. Many have tried and failed.
Of course there is a good explanation for dowsing: the wires, stick or whatever is completely controlled by the dowser. Just put a blindfold on the dowser and see what happens.
