^^ water is never pure, there will always be mollecules of other substances in it, even bottled water has minerals and a whole other mess of stuff in it.

 

Not if it's bottled distilled water.  That's about as pure as you'd get.

There is still other particles of minerals in that too, it makes it healthier so taking them out would be stupid.

 

Do you even know what distilled means?  Distillation of water involves boiling the water, then taking the steam and condensing it in a seperate container.  All minerals will be left back in the original container as residue.  Distilled water is not meant for drinking precisely because it has no minerals.  It is meant to be used when highly purified water is necessary for uses like decontamination.  If you drink too much distilled water, you die.

From Wiki - "Distillation Gathering water through the use of a bag is a much employed survival technique Gathering water through the use of a pit is another much employed survival technique Distilled water has virtually all of its impurities removed through distillation. Distillation involves boiling the water and then condensing the steam into a clean cup, leaving nearly all of the solid contaminants behind. Distillation produces very pure water but also leaves behind a leftover white or yellowish mineral scale, which requires that the distillation apparatus be frequently cleaned." notice the use of "virtualy"

I was aware that distilled water is "virtually" pure and not "absolutely" pure.  But I had only said, it's about as pure as you get (and of course I meant practically speaking).  While you said, distilled water still has minerals in it because it's healthier that way, and taking them out would be stupid.  Poiniting a small flaw in my statement (if there even was one) does not make the much bigger flaw in your statement disappear.

Distilled bottled water is about as pure as you can get, and if you filled a white tiled indoor swmiing pool with it, the pool bottom would look blueish.  It won't be because the water is impure, or because there is sky reflected in it, ot because of the color of the bottom tiles.  It will be so because pure water actually has a blueish color, which becomes only apparent when there is a tall enough column of it.  Look at the picture posted couple of posts above this, and you can clearly see that a tube of distilled H₂O looks blue while that of D₂O does not.
