Japanese scientist Masaru Emoto discovered that human intention and consciousness have an impact on the structure of water. He demonstrated this through experiments where he would freeze a drop of water and observe the structure under a microscope. He used different people and had them say positive or negative statements to the water.
Under the microscope, positive statements would show beautiful structures, while negative statements showed chaotic and ugly structures. More interesting still, even labeling the containers with positive and negative statement would yield the same results.
