if its the one were you have water in a pie pan and you have a candle standing in the water and when you light it and then you put something like a beaker over it and it takes a minute to go out, then i have your answer. there's only 20% oxygen inside the beaker and the flame uses most of it, but not quite all of it. the heat from the flame makes the air expand and when the flame dies and the starts to cool down, it makes the air contract and that makes the water level rise as it attempts to follow the hot air. it was really neat when we did it in my freshman Physical Science Lab class!
