How a candle works

A candle is an object that produces light and a bit of heat. A candle is made up of wax, a wick and a flame (which you need a match to light). But how does it work?

The wax part of the candle act as the candles food. The other food for the candle is oxygen. The candle needs these to make it go. The candle absorbs the wax by melting the top of the wax to make it liquid wax and then soaking it up the wick to the flame. It eats the 'nutrients' (stuff it needs) and leaves the rest in its liquid form. The effect is you have used a match, heat, liquid wax, some smoke and burned oxygen.
