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.
