Nutella is good on toast, with ice cream, or eaten by the spoonful while gently sobbing. But as it turns out, add a dash of potassium permanganate and a little heat, and you have yourself a good little fire.

The mixture of potassium permanganate and Nutella (about 1:4) gives a sticky, slow-burning reaction that would make for a genuinely useful firestarter.
