The Diet Coke and Mentos reaction is impressive experiment that is easy to perform. Simply drop a few Mentos candies into a bottle of Diet Coke (or any other carbonated beverage), and a fountain of fizzy soda sprays out. Several interesting physical and chemical processes are involved in the formation of this fountain. This talk will focus on many of the scientific topics that relate to this experiment, including gases, solubility, rates of reactions, effects of temperature, graphing, and inquiry-based explorations. Interestingly, the effect of air pressure at various altitudes on this experiment can also be investigated. Furthermore, several myths and misconceptions related to the Coke and Mentos geyser will be discussed. Finally, activities that connect this interesting experiment to topics in the science curriculum will be explored.
