In this article, we report some experimental results on the behaviourof the flame of a candle kept at the bottom of a glasstube, which is open at the top and closed at the bottom. Thus,the supply of oxygen for the continuous burning of the flameis possible only from the top open end of the tube. We findthat the candle burns steadily below a critical tube height.Above this height, the flame oscillates in size, and a further increasein tube height leads to the flame extinguishing quickly.
