Eli5: What happens to all the melted candle over time? Are we just inhaling a whole candle while it burns?
In: Chemistry
The wax is the fuel, the wick is just a ladder for the melted wax to climb up so that it can evaporate from the heat of the flame and burn more easily. The wax that drips down the sides is just wasted fuel, no different than if you spilled gasoline down the side of your car.
