Aitch Two Oh

My daughter was thirsty the other day when we were visiting the "Specialty" grocery store, and she found this on the shelf. She wanted to buy it, but I didn't think snake oil was a healthy drink.

Seriously, hydrogen infused water?

Somebody explain to me how this can possibly be a thing? Does the H in H2O not mean anything? How did they infuse the water with hydrogen? If they put extra hydrogen in water, doesn't it stop being water? What is H3O? I know that CO2 changes substantially when it becomes simply CO.

Anyway, humans don't need crap like this. We evolved to eat and drink certain stuff, and snake oil was not one of them. There just wasn't enough snakes around to be a large part of our diet.
