For the coherent structure of the full spectrum coherent water contained inside the vial to be successfully copied to surrounding water molecules, the vial had to be designed in a specific way. During development, we tried out numerous materials before we found that quartz has a specific physical composition which allows a seamless transfer of energy between the inside and outside of the vial. The ultra-thin quartz vial holds the mother water inside, but at the same time allows the transfer of its coherent structure.
