I've just finished a year as secretary of the Cambridge University
Scientific Society, and I remember one of the talks I couldn't make was by
a dowser. His name was Guy Hudson, and he was scientific advisor to the
British Society of Dowsers. He was going to do a demo/workshop but we
couldn't find an appropriate floor in the centre of Cambridge. Sounds like
some research has been going on, though.
