...based on the work of Japanese scientist Dr Masaru Emoto. He's done countless studies that suggest the molecules in water crystals could be affected by our thoughts, words and feelings, thus determining the shape of the crystals.
His tests reveal that molecules exposed to happy or loving environments form beautiful, symmetrical crystals, while those exposed to unpleasant influences are misshapen.
