1) the authors mention "distilled water" vs. non-distilled water, without reference to what is in the "non-distilled" water.
Those incapable of understanding that all non-distilled water is not the same, and that without defining its contents precisely, you look like idiots when discussing it and should be relegated to kindergarten.
Or at least don't post such nonsense here.
For the umpteenth time - there is a distilled water forum and a water forum on CZ. Why yoooz goys are compelled to keep coming back here with distilled water topic suggests something to me.
