Description: Two enhancements to the standard demonstration apparatus: using a ground fault interrupt (GFI) to reduce the risk of electrocuting the demonstrator, and using potassium chloride (a dietary salt substitute) to produce a pink glow rather than the traditional sodium yellow. Also discusses the mechanism of the single-ended glow.
Glow little pickle, glimmer, glimmer... When a high voltage is applied across a pickle the pickle will emit a yellow glow. Warning! This is a dangerous, possibly deadly activity. We publish it to show a safer way of doing the experiment using a ground fault interrupt. Do not do it unless you use the ground fault interrupt circuit we introduce below, and unless you are skilled in working with potentially lethal voltages of alternating current.
