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.

Stilling Waves with Ordered Molecular Monolayers  Ed Vitz
The amazing ability of a film of oil one molecule thick to dissipate the relatively large energy of water waves can be readily demonstrated, but an explanation of the effect has been elusive until recently.

Thirty Feet and Rising: Constructing and Using a Water Barometer To Explore Chemical Principles  Hans de Grys
This article details the construction of a three-story tall water barometer and outlines several important chemical principles that can be explored with such a device. Not only can students develop an intuitive understanding of pressure and how a barometer works, the experiment can be extended to explore vapor pressure, phase changes, equilibrium, and gas solubility.
