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. This experiment is inexpensive to set up and can be easily completed in less than an hour.

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
