Emoto believed that water was a “blueprint for our reality”[clarification needed] and that emotional “energies” and “vibrations” could change the physical structure of water. Emoto’s water crystal experiments consisted of exposing water in glasses to different words, pictures or music, and then freezing and examining the aesthetic properties of the resulting crystals with microscopic photography.Emoto made the claim that water exposed to positive speech and thoughts would result in visually pleasing crystals being formed when that water was frozen, and that negative intention would yield “ugly” frozen crystal formations. This phenomenon was not published in any peer reviewed scientific journal, and the best quality study Emoto published on the effects of human intention on the structure of water did not yield positive results.

Emoto claimed that different water sources would produce different crystalline structures when frozen. For example, he claimed that a water sample from a mountain stream when frozen would show structures of beautifully-shaped geometric design, but those structures would be distorted and randomly formed if the sample were taken from a polluted water source. Emoto believed that these changes could be eliminated by exposing water to ultraviolet light or certain electromagnetic waves.
