How does a candle work?

Well, honey, a candle works by burning a wick that is soaked in wax. When you light the wick, the heat melts the wax, which then gets drawn up the wick and vaporizes. The vaporized wax then combines with oxygen in the air to produce a flame. Voila, you've got yourself a little flickering light to set the mood or cover up that funky smell in the bathroom.
