Google has hosted a series of talks by famous persons. One of the series is from authors.
James Randi was one of the guests, and spoke about homeopathy, dowsers, and other pseudoscience.
If that topic tweaks your interest, you can see a 45 minute documentary about Randi's trip to Australia to test dowsers. This is a very entertaining and often humorous video.
You might also enjoy a televised test of a guy who claimed he could move phone book pages with mind power. This one is really funny!
