Whenever I want a drink of water, I fill the glass but then go out and find a leaf (from a non-GMO tree of course), float the leaf on the water and put a needle on it. If the leaf/needle spins and ends up pointing north/south, then the water is polarized and is drinkable. If the leaf + needle sink, they are innocent but I won't drink the water because it has a leaf in it. And a needle. Which is a choking hazard.
