Science Behind: Candles

Do you know that when you breathe near a candle you are breathing in wax?

When you burn a candle, the wax near the wick melts and through capillary action (as the wax sticks together and moves up the wick) the wax moves up with the wick. The heat of the flame of the candle then makes the wax into a vapor which then reacts with the flame to produce light.

Heat is then created that keeps the burning of the wax going, and the cycle continues until the flame goes out.

So, essentially, you are breathing in particles of wax. Isn’t that interesting?
