Heat things up with Vaseline
Posted in backpackers, equipment by JohnJohn on October 23, 2007
Rub a couple of cotton balls in Vaseline, then store them with some flint and steel. LifeHacker says this makes a great fire starter.
Popular Mechanics says that a cotton ball smeared with Vaseline or ChapStick is “a foolproof fire starter.” The Vaseline works as your fuel, and once you get the Vaseline-soaked cotton ball lit, the flame should continue to burn under pretty much any condition. The Popular Mechanics article is rather light on details, so I also found a post on the Survival and Equipment weblog detailing how to make single-use petroleum jelly candles using cotton balls, petroleum jelly, and aluminum foil. You will, of course, still need a flint or match to get the cotton ball started.
I think matches or a lighter is easier.
