Though funnily enough, you can make real 'structured water' at home in your freezer. Making your ice crystals hexagonal is theoretically possible, but it's really, really hard to grow monocrystaline water ice. That might be a really interesting niche hobby, though.

See https://www.youtube.com/watch?v=VA710QYxEu0 for the latter.

Well yes, that’s in a solid state. Lots of crystals have hexagonal structures since it’s the optimal packing distribution.

If “structured water” just means that there are tiny ice crystals in water, sure that’s very plausible, but I doubt it would have much of an effect.

PS: Trying to grow crystals of different challenging structures does sound like an awesome hobby.

Oh, the pseudo-science 'structured water' is absolutely bonkers. I just went off on a mildly interesting tangent.
