The Ultrasonic Soda Fountain: A Dramatic Demonstration of Gas Solubility in Aqueous Solutions John E. Baur and Melinda B. Baur An ultrasonic bath is used to accelerate the rate at which carbonated beverages equilibrate with the atmosphere. The resulting fountain, which can reach heights in excess of 3 meters, is a dramatic demonstration of the solubility of gases in liquids. Baur, John E.; Baur, Melinda B. J. Chem. Educ. 2006, 83, 577.
