Spring water. You forgot to mention spring water. (... and distilled water isn't water at all. it lacks almost all properties of real water. Specifically, it tastes horribly, as opposed to spring water)
@helenS Ok explain that. You are saying that water converted to steam is not water? And that steam condensation is not water? And that its toxic to consume and will kill you? None of that is true.
@helenS Distilled is the purest water in the world, and has no taste, I drank it for years, until a dr told me to stop as it was leaching electrolytes from my body.
@LeopoldBloom I think scientists shouldn't use ordinary language words to give a chemical substance a name. I would call pure H2O "hydrogen oxide". "Water" is much more than just that. It's a mixture of many things; it contains dissolved molecular oxygen (without which fish could not survive in water), dissolved CO2 (a part of which reacts with hydrogen oxide to form HCO3-), and a variety of ions such as sodium ions, potassium ions, calcium ions, etc. That's water.
