Potassium Permanganate is among the most useful ingredients to be included in any First Aid or Emergency Preparedness Kit. It can be used to sanitize wounds and to purify water. It is inexpensive and a little bit goes a long ways. It can be used to make fire in an emergency situation. I have presented a couple of fire-starting methods using PP within this blog already. Here is another.
Combining equal parts of sugar and permanganate and grinding them up finely together prepares the mixture for ignition by adding moisture and by adding friction. You can rub the mixture with a stick, but unless the stick is still green with sap moisture, it may not be sufficient to get fire. In this clip I added a single rose petal to get the moisture, which then quickly ignited by rubbing friction. The following video clip shows adding a rose petal for the moisture and rubbing the mixture with a dry stick for the friction. View the clip to see what happens.
