101 Uses: Potassium permanganate

Maybe not 101 uses but it has several important ones and it has been a very popular item in many survival kits for a long time, typically a small vial with potassium permanganate crystals in it.
Before going any further: 1) Its can be dangerous in many ways when misused 2) It does stain with a red/purple tint that is hard or impossible to remove.
What’s it good for?

Water purification: 3 or 4 crystals per liter of water. You want to have a very light tint of pink. Stir and leave it for 30 minutes.

Fungal and wount cleaning:
Another common use. As a matter of fact, its commonly used for fishtank cleaning and killing fungus in fish. Add a few more crystals until you have a darker tint of pink.

Hand sanitizing: This same solution can be used to wash hands.

Dissolve some in water to get a bright pink/purple solution for coloring white or clear colored fabric. You can also spread it on snow to make a visible signal.

Fire starter: 1 part sugar , 2 parts potassium permanganate, grind into a thin powder and it will light with a spark from a ferrocerium rod (fire steel).

I ordered a pack on line but you can also buy it from some aquariums or veterinarians since its used for fish tanks.
