Hexagonal water, also known as gel water, structured water, H3O2 or H3O2 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. Gel water is referenced in the version of the hoax in which plants or animal fascia are said to create or contain a "fourth phase" of water with an extra hydrogen and an extra oxygen, despite the simple reality that this compound is neither water, nor stable—in other words it doesn't exist in any practical sense.
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.
Proponents of the hexagonal water model claim that the measurable differences between commercially available "hexagonal water" products and tap water under 17O Nuclear magnetic resonance spectroscopy indicate hexagonal water's special properties. However, this technique shows no significant differences between the supposed "hexagonal water", ultrapure water, and human urine. The experimental observation of water clusters requires spectroscopic tools such as Far-infrared (FIR) vibration-rotation-tunneling (VRT) spectroscopy (an infrared spectroscopy technique).
