Yeah okay... Surprised to see this as the top comment.

> Hexagonal water, also known as gel water, structured water, cluster water,[1] H3O2 or H3O2 is a term used in a marketing scam[2][3] that claims the ability to create a certain configuration of water that is better for the body.[4]

> 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.[7] This contradicts the hexagonal water model's claim that the particular structure of water consumed is the same structure used by the body.

A so-called fourth phase of water (liquid, but with some crystalline organization) that grows on hydrophilic surfaces by absorbing ultraviolet and infrared light, and organizes into a honeycomb-like lattice similar to ice, but lacking the H+ binding layers to make it rigid. It has higher viscosity than bulk water, and a net-negative charge.

Yes, it's a relatively recent concept (decades) pursued mostly by Gerald Pollack at University of Washington and not widely replicated, though there is some replication that has prompted critical review (https://pmc.ncbi.nlm.nih.gov/articles/PMC7404113/). It's also downstream of work by Albert Szent-Györgyi (Nobel prize for vitamin C) and Gilbert Ling. And, of course, there are a bunch of folks Pollack distances himself from commercializing the concept.

If I had a coloring book for every person who cited wikipedia as a reliable source on cutting-edge science... I'd have Christmas presents for a bunch of people I don't know!
