Soda Can Density and Unexpected Results Erica K. Jacobsen, Donald R. Paulson, and Michael J. Sanger
Reader Donald R. Paulson reports on an unexpected result seen while performing a sink/float test similar to that described in the JCE Classroom Activity "Whatever Floats (or Sinks) Your Can", and describes an extension to the Activity. Activity author Michael J. Sanger and JCE editor-in-chief John W. Moore also discuss possible extensions.

Trusty or Rusty? Oxidation Rate of Nails Stephen W. Wright
Students investigate the process of rusting using supermarket chemicals. Steel nails are placed in gelatin and allowed to react with atmospheric oxygen. Ferric ion produced by the oxidation is made visible as a garnet-colored complex formed by the magnesium salicylate in backache tablets. Factors that accelerate or retard the rate of iron oxidation are studied.

Crystals Out of "Thin Air" John J. Vollmer
In this experiment crystals of para-dichlorobenzene form readily and efficiently from mothballs in a safe setting, using canning jars with ice cubes. The experiment can serve as an introduction to the concept of molecules, especially when combined with the condensation of liquids and the perception of odors.
