Once the liquid wax gets hot enough, it then turns from a liquid into a gas. Because the wick is absorbent it sucks the liquid wax into the wick and upward into the flame. As the wick burns down the heat of the flame melts the wax around the wick. To start that heating process, you first need to light the wick with another source of fire, such as a match.

But before the wax can become fuel it first needs to get hot enough. The combustible material in a candle-or its fuel-is the wax. Combustion is the result of a chemical reaction in which oxygen gas reacts with the substance that is being burned. So how do these two materials come together to help a candle burn steadily?ДЄ lit candle might seem simple, but it is actually an example of a multi-step process resulting in combustion-and the glowing flame you see. Through the center of the wax runs a wick, which is usually made from cotton or other material that can absorb liquids well. This style of candle dates back to the ancient Romans.

Whether they are on a birthday cake or dinner table or menorah, most candles we use today are wax-dipped candles. Have you ever looked closely at the flame? Which part of the candle is actually burning? Can you tell? Is it the wick, the solid wax, the liquid wax or something else? In this activity you will light some candles to find out-no special occasion required! There are many occasions to light candles.
