Light a candle and place a jar over it. Also keep a tray underneath which is filled with water so that it becomes air tight. After sometime the oxygen inside the jar is consumed ,releasing carbon dioxide. In the absence of oxygen,the flame goes off. This shows air supports burning.

Take a candle and try to burn it in air. Take another candle and try to burn it while keeping it submerged in water. You will observe that, while the candle burns in air; it does not burn in water. This simple activity shows that air support burning.
