Harmless at what level? Because even the most harmless chemical substance will become harmful at high enough doses.
- wwer 10y agoYup. I heard this di-Hydrogen Oxide can be fatal in very high ingestion cases.
- Coincoin 10y agoI don't know why you are down voted. Your comment is the very first thing that went through my mind when I read the article. Next time, you might want to use Di-hydrogen monoxide, it's a much scarier name. Everybody knows monoxide is dangerous on anything.

- hwillis 10y agoThe "pink" amount appears to be in the range of 1-3mg/L. So the LD50 for an 80kg man would be ~30,000 liters orally. That would certainly be lethal. The rule of thumb for this stuff is also "If it's pink, it's safe to drink"[1], as in pink is the minimum concentration to ensure safety. The only reason to avoid higher concentrations is that it will stain heavily. 1: http://bluecollarprepping.blogspot.com/2014/08/potassium-permanganate-for-water.html http://bluecollarprepping.blogspot.com/2014/08/potassium-per...
