Crystals Out of "Thin Air".
Vollmer, John J.
Journal of Chemical Education, v77 n4 p486-88,488A-88B Apr 2000
Describes how to grow crystals of para-dichlorobenzene beginning with household mothballs. The crystals form through sublimation (solid to gas) and deposition (gas to solid). Also discusses demonstrations of evaporation and condensation and odor perception, which can support a study of the kinetic theory and phases of matter. (WRM)
