Why does a candle extinguish itself after being covered with a glass?

The burning flame on a candle needs three things to continue burning:
1) fuel, which it gets from the wick
2) heat, which comes from lighting the candle
3) oxygen
Without any one or more of these three things, the candle will no longer continue to burn. In the case where a candle is covered with a glass, the candle quickly uses up the oxygen inside the glass. once all of the oxygen is gone, the flame will burn out.

Why does a candle flame extinguish after blowing air on it?
Air exhaled contains a higher concentration of carbon dioxide, which can act as a fire extinguisher. OR The fast moving air causes a reduction in the heat available to the candle flame, thus extinguishing it. Heat is one of the 3 essential components of the fire triangle, the other 2 being fuel and oxygen. When you "blow out" a candle flame, you are rapidly reducing the temperature of the wick and cooling the burning material to below the ignition point.
How do you extinguish the candle?
