Hexagonal water

Hexagonal 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 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.
