Crystals Out of "Thin Air"
John J. Vollmer
Department of Chemistry, Mills College, Oakland, CA 94613
Cover
April 2000
Vol. 77 No. 4
p. 486
Abstract
Sublimation is an excellent method to introduce crystals and crystal formation. 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. This sublimation is presented for elementary school teachers, but can be an effective demonstration in other settings.
