. . tap-water in Onoway, Alberta, turned fuschia for more than a day - bright, deep pink! . http://www.livescience.com/58181-why-water-turned-pink-in-alberta.html . . they note it's supposedly "not dangerous", but then add that potassium permanganate "can cause skin irritation", so residents with 'sensitive skin, may not want to bathe in it'. . Hell's bells, my stomach & gut are way-more 'sensitive' than my skin! - I wouldn't be putting that anywhere near my mouth, not even to rinse vegies or fruits. . . .
