The PSSC soda straw balance is adapted to make it applicable to a study of Coulomb's law. Because of the inherent simplicity of the balance, it is well suited to nonscience students as well as physics majors. A calculation is made to determine a correction for the redistribution of charge as conducting spheres of finite radius are brought near each other in the Coulomb's law experiment. Typical data are presented to illustrate the value of this simple balance as a teaching device.
