Believe it or not, the Crazy Russian Hacker knows what he's talking about.

This time, he's used two household ingredients that can turn an ordinary tub of Nutella spread into a batch of moldable and very flammable goop. This ingenious hack could save your ass, if you're ever lost in the wild and can't find your hotel.

Take some notes, Bear Grylls.

The secret to the magical Nutella fireball spread seems to be potassium permanganate crystals, which is not necessarily as dangerous as it sounds. Although, some forms of it are available by prescription only, according to the FDA.

But, there are some safe at home uses for potassium permanganate, that can seem pretty soothing. Potassium permanganate can also be found inside industrial cleaning products.

As for the whole, "for prescription use only," jargon, you can purchase your very own bottle of potassium permanganate crystals on Amazon for less than $20.

So, remember to add Nutella and potassium permanganate to your zombie apocalypse survival kit.
