They two hosts of Dual Survival were given an e-cig as a "survival supply" recently during an episode on the Discovery Channel, turns out that if you mix the e-liquid and potassium permanganate you can start a fire with it.
I saw that episode and decided to look up why a volcanologist would be carrying a bottle of the potassium and didn't find much. Entertaining anyhow!
