James Randi in Australia, 1981 

All credit should go to Australian Skeptics, as well as the copyright. Found this on the web way back and thought I would post it to give it - hopefully - the wider audience it deserves.
The classic documentary produced by Dick Smith. James Randi travels to Sydney in 1980 to conduct a thorough and fair test of water divining or water dowsing. This event was one of the inspirations that led to the formation of Australian Skeptics in 1981.
