A dramatic demonstration of the principle behind sodium arc lights, by passing an electrical current through a pickle of other salty foods.

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.
