He's quite a character to talk to.

Glad you dropped in. For general edification, can you give an example of what Mr. Randi would consider a double blind test?
Flyingorb, for a brief description of what a double blind test is, check out this link: http://www.skepdic.com/control.html
I'll see if I can find specific examples in tests that Randi has overseen by searching his weekly commentary archives - it may take a while though. As a general rule it'll go something like this:
A dowser says he can detect water using dowsing rods. He agrees to a test in which a volume of water is placed within one of ten sealed containers. These containers would be given an ID by an independent third party and randomly arranged such that only this third party knows which container holds the water. The dowser would then attempt to detect the water, overseen by another group who will ensure the tests are carried out correctly. In this way, neither the dowser nor the 'test overseers' would be aware of where the water was. Once the dowser has identified which container he thinks holds the water, the third party will be brought in to reveal whether the 'guess' was correct.

I promised you a clear example of a JREF double-blind test, FlyingOrb - and here it is: Randi's suggestion of a protocol for testing Penta water. It's towards the bottom of the page - Randi's response to the Penta water seller's recommendation of the use of a Bio Impedance Analyzer. Hope it helps.

Smaller clusters of water indeed! Even ice is more of a crystal lattace. This nonsence about the "smaller clusters" of water is the kind of fraud I like to see exposed.
