In this video:
Candles themselves work on a fairly simple and ingenious principle. The three elements to sustain fire are concealed in one convenient package. The fuel itself is the container made of wax. The catalyst that heats up the fuel is the wick. Once lit, the wax that is surrounding the flame melts and is drawn into, and up the super absorbent wick. The closer the wax gets to the flame, the hotter it becomes. By the time it reaches the flame, it is hot enough that the wax vaporizes and it is the wax vapor that burns. The oxygen it needs is ever present in the air at approximately 21%.
