Abstract

A single, dramatic, and enjoyable demonstration can be employed as a tool to maintain student concentration and interest throughout a college chemistry lecture period. The use of the "hot dog clock" has been the focus of discussions in a number of areas of electrochemistry. Included in these have been oxidation-reduction potentials, battery construction, salt bridges, electrolytes, and the concentration of ions in certain foods. Portions of the material presented have also been important components of chemistry presentations to a variety of audiences.
