Candles are powered by combustion reactions. When you light a candle wick, the wax around the base of the wick melts. Through capillary action, this liquid hot wax is drawn up the wick. The heat of the flame turns the wax into a hot gas (a.k.a. vaporizes it) and starts to break down the wax into molecules of hydrogen and oxygen.Cover the top of the candle with aluminum foil. Cut or fold a small opening (around 1-inch) in the center of the aluminum foil. Remove the aluminum foil, light the wick, then place the foil cover back on.*. Allow the candle to burn for a few hours until the top surface of wax has completely melted and smoothed over.I've always wondered about the use of oxygen bottles vs oxygen candles.
