Japanese author and doctor of alternative medicine, Masaru Emoto claims that water can react to intentions. Talk nice to water and you get nice looking ice crystals from it. Mention Adolf Hitler near water and the ice crystals are all distorted and ugly.
Let's not discuss theoretical objections to this. I'm interested in experiments that tried to test this. Do you know any?
Only studies I could find were conducted by the Emoto and his colleagues.
For example, Wikipedia mentions the following experiment as a criticism:
A better-controlled "triple-blind" follow-up study published in the Journal of Scientific Exploration did not yield positive results. More than 1,900 of Mr. Emoto's followers focused gratitude on water bottles in a vault over a period of three days. The water was then frozen and compared to two different sets of controls. Crystals from all three groups were not considered to be particularly beautiful (scoring 1.7 on a scale of 0 to 6, where 6 was very beautiful). An objective comparison of contrast did not reveal any significant differences among the samples.
Here is a beauty rating graph of 3 sets of water:
In the paper they reduce the result set (use beauty > 1 ratings) to prove them right.
But even if results do not really support Emoto claims, why is there a difference in beauty ratings of different sets of water at all? Shouldn't the ratings be about equal?
