Fog Machines, Vapors, and Phase Diagrams Ed Vitz
This series of demonstrations elucidate the operation of commercial fog machines using common laboratory materials and can be adapted for elementary through tertiary levels. The formation of fogs is discussed in terms of the phase diagram for water and other chemical principles.

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.
