Stand a large beaker full of air upside down over a container filled with lime water which has a lit candle (tea light, night light) floating on its surface. The flame from the candle will burn off the oxygen in the air which will cause the water to rise within the beaker. The water won't rise right up to the top which proves that their are other substances besides Oxygen in the air. And before you say that it is just the Carbon dioxide which has been produced by the burning of Oxygen, that is why Lime water was used. Lime water absorbs Carbon dioxide. So, whatever remains in the beaker is neither Oxygen or Carbon dioxide.
