Natural corks from wine and champagne bottles are a great way to start a roaring fire. Local restaurants and bars are a great place to get corks for free -- just ask a bartender to set aside a few for you. Fill a jar with corks and pour rubbing alcohol to the top. Let the corks soak up the alcohol. When you're ready to start a fire, remove a cork and light it, and it will start a slow, even burn. Remember: Use natural cork only and not plastic to make these fire starters.
