There's a lot of chemistry behind the simple lighting of a candle. Oxygen is needed for the candle to burn, the melting (vaporizing) wax provides the fuel and, of course, you need heat. Remove any of the three (oxygen, heat or fuel) in the fire triangle and the flame goes out. Yet another way to extinguish the fire is to smother it with carbon dioxide gas. Because you have a flair for doing cool science experiments, you'll learn how to blow out a candle with a little style and showmanship.
