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.

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.
