A local TV station is showing "Water Revitalizer" which supposedly produces a purer "hexagonal water" which is supposedly better for you. (in case you are in the SF Bay Area, it's on the ICN channel, I think it's 26-4 or something like that)
First of all, there is no such thing as hexagonal water. It's something invented by quacks as "pseudo-science" to explain the hexagonal shape crystals the water forms when it freezes, and claims if you can generate hexagonal water it's better for you. Why? Nobody can actually explain.
Chemically it's exactly the same as normal water. It doesn't go through any sort of filter or purification in this special pitcher. All it does, as far as I can tell, is it uses induction to 'spin' the water (kinda like that Nu Wave oven demo). How that generates hexagonal water? No ****ing clue.
Yet you can find one for sale on Amazon for $500 USD ?!?!?! AND books that touts the supposedly benefits.
It's gotten so bad, even WIRED magazine have an article busting this scam.
