This survivalist based in Nelson, New Zealand, shows how his favourite chemical compound can be used to purify water, cure fungal infections, and start fires.

The filmer swirls a tiny bit of potassium permanganate into a glass of water and explains that the compound purifies the liquid.

He then goes on to explain how adding more of the chemical turns the liquid into an anti-septic.

Finally, he mixes the potassium permanganate with a type of alcohol called glycerin and starts a fire.

Potassium permanganate has a variety of uses, for firestarting or even water purification. As well as signals in the snow. It is cheaper than a box of matches or water purification tablets allowing you to save money,
