Abstract
A glass filled with carbon dioxide gas upside down on a plate of waterconstitutes an excellent demonstration of the solubility of gases. If the waterlevel on the plate is maintained the CO2 will slowly dissolve and the columnof water will rise inside the glass, without quite reaching the ceiling, before anopposite process sets in: the water level will even more slowly begin to sinkin a process which will take several years. We followed the process for severalmonths, recording images of the water column with 10 min to 1 h intervals.The physics of the process is discussed and modeled quantitatively.
