Masaru Emoto (江本 勝 Emoto Masaru, July 22, 1943 – October 17, 2014) was a Japanese author, researcher and entrepreneur, who claimed that human consciousness has an effect on the molecular structure of water. Emoto’s conjecture evolved over the years, and his early work explored his belief that water could react to positive thoughts and words, and that polluted water could be cleaned through prayer and positive visualization.
Emoto believed that water was a “blueprint for our reality” 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.
