Interesting article where the author takes some rubbing alcohol and uses a “real” cork to absorb it to act as a candle wick. Guess it would be a good thing to use in a pinch for a candle. I like the other idea of putting a bunch of corks in a mason jar with the rubbing alcohol and using them as needed for fire starters.
