Hexagonal water, also known as structured water, is a term used in a marketing scam that claims the ability to create a certain configuration of water that is better for the body. The term "hexagonal water" refers to a cluster of water molecules forming a hexagonal shape that supposedly enhances nutrient absorption, removes metabolic wastes, and enhances cellular communication, among other things. Similar to the dihydrogen monoxide hoax, the scam takes advantage of the consumer's limited knowledge of chemistry, physics, and physiology.
Incompatibilities with science
The concept of hexagonal water clashes with several established scientific ideas. Although water clusters have been observed experimentally, they have a very short lifetime: the hydrogen bonds are continually breaking and reforming at timescales shorter than 200 femtoseconds. This contradicts the hexagonal water model's claim that the particular structure of water consumed is the same structure used by the body. Similarly, the hexagonal water model claims that this particular structure of water "resonates with energetic vibrations of the body to amplify life force". Although water molecules strongly absorb energy in the infrared range of the electromagnetic spectrum, there is no scientific evidence that supports the theory that hexagon-shaped water polymers would be created through bombardment of energy of these frequencies.
In addition, the hexagonal water model's claim that water's structure can be determined through nuclear magnetic resonance (NMR) imaging is inconsistent with the limitations of the method. In laboratory settings, NMR imaging instruments cannot distinguish between pure water, impure water, or urine. The experimental observation of water clusters requires spectroscopic tools such as Far-infrared (FIR) vibration-rotation-tunneling (VRT) spectroscopy (an infrared spectroscopy technique).
