This calls for a "I'm not even mad, that's amazing." meme. It really just shows how deep superstitions can go. Even the company that defended it clearly knew it wasn't an effective method:

Wow, this is the most amazing story I've read in a while. Are dowsing rods really believed to be a successful method of finding water by a decent number of people?
