Cover: Exploring the Candy–Cola Soda Geyser

When Mentos candies are dropped into a bottle of a carbonated beverage, nucleation sites on the surface of the candies induce rapid dissolution of CO2 gas from the drink. This produces an impressive, messy, and foamy fountain that spouts several meters high and cascades down. In , Trevor P. T. Sims and Thomas S. Kuntzleman discuss simple protocols that allow students to monitor the dynamics of CO2 escape during this fascinating experiment.  Quantitative analysis of data collected is possible, allowing students to quantitatively explore topics in chemical dynamics. Given the popularity of this candy–cola soda geyser, these investigations can provide a motivating backdrop through which students can examine concepts in kinetics or conduct small research projects. To enable visualization of events inside the bottle, the cover shows events occurring inside and nearby a bottle of a clear and colorless carbonated beverage to which Mentos candies have been added. The entire sequence shown lasts less than four seconds.

Editorial: Forensic Chemistry

While forensic science deals mainly with the aftermath of crime, the flip side is the science of eliminating or ameliorating violent acts before they happen, as discussed by Robert Q. Thompson in .
