Use Potassium Permanganate to purify water

You can use Potassium Permanganate crystals to purify water. Put in a couple of crystals in a liter of water and let it sit for about half an hour. Once the colour of the water turns bright pink, it is good to drink. If it is a light pink, add another crystal. If it is too pink, almost red, it is not good to drink. You can store it and use it as an antiseptic solution. Visit http://OTASurvivalSchool.com.
