Experiment

I did an experiment in class where I would fill a plate with water, put a lit candle in the middle, and cover it with a cup/jar. The outcome was that the water from the plate would all be sucked up into the cup.

How does it work?
The candle would burn out all the gases in the jar creating a lack of oxygen causing a change of pressure inside the jar. The flame heated up the jar and then once all the oxygen burned away, the candle would go out. The drop in temperature would create a vacuum-like suction to pull in all the water.
