Subject: Burning Candle Experiment ... We are taught that the rising water level is caused by oxygen being consumed by the burning candle. However, if we have four candles burning under the glass instead of one, the water level rises much more. Why? I have repeated this experiment and am surprised to find this is true.

Repeat the experiment several times until you can write down or draw a picture that explains why the water level rises. ... The candle needs oxygen to burn. When you cover the burning candle with the jar, the flame eventually goes out as soon as all of the oxygen is used up. Since there is no more oxygen under the cup,

You don't describe how you are performing the experiment but if you are burning the candle in a closed container you will produce a significant amount of carbon monoxide. This will impact how much water is produced through the use of the limiting reagent (oxygen).

However, I have another issue with a variation of this experiment. If I burn the candle in a jar over water, the water is expected to rise to fill the space occupied by the oxygen, if "hot gas" and other effects are avoided.

In this experiment you will make observations of a deceptibly simple process: a burning candle. In fact, what takes place during the initiation and dynamically stable combustion process is enormously complex. ... A Burning Candle: An Experiment in Observation...

I1-64: BURNING CANDLE - COMBUSTION PROCESS ... The candle in our experiment is placed inside the sealed tube containing air above a colored water bath, and is then ignited by a hot wire. The water level goes down initially, then returns to its original level just after the candle goes out.
