It also works if you replace the glycerol with finely ground sugar and a little friction. I agree that it is a bit unlikely you would have potassium permanganate with you, but it is fun.
You don't need to carry glycerine, just mix equal amounts of PP and sugar on a hard surface and apply friction by rubbing with a stick. It will ignite. Most people carry sugar the only the permanganate is out of the ordinary.
