Abstract

There are many demonstrations about electrical conductivity that are illuminating, but the incredible glowing pickle is the most dramatic and eye-catching. In this paper we describe how to achieve the same effect with an onion, a potato, a head of cabbage, and a grapefruit, as well as a simple and safe device to hold these foods. An explanation as to the mechanism of the glowings is also described.
