Some people, when faced with claims like Dr. Emoto's "intention affects the formation of water cystals," immediately dismiss it as nonsense. Others uncritically accept the claim because it sounds nice. My first reaction is to try to replicate the claim to see it for myself. I conducted such a test with Dr. Emoto, where he and his staff were kept blind as to which bottles of water had been treated. The paper reporting the experiment has just come out. Here's the abstract:
DOUBLE-BLIND TEST OF THE EFFECTS OF DISTANT INTENTION ON WATER CRYSTAL FORMATION
The hypothesis that water “treated” with intention can affect ice crystals formed from that water was pilot tested under double-blind conditions. A group of approximately 2,000 people in Tokyo focused positive intentions towards water samples located inside an electromagnetically shielded room in California. That group was unaware of similar water samples set aside in a different location as controls. Ice crystals formed from both sets of water samples were blindly identified and photographed by an analyst, and the resulting images were blindly assessed for aesthetic appeal by 100 independent judges. Results indicated that crystals from the treated water were given higher scores for aesthetic appeal than those from the control water (p = 0.001, one-tailed), lending support to the hypothesis.

A triple-blind replication of this effect is presently underway.
