Applying line voltage across a pickled cucumber causes it to glow. A moist pickle contains salt as a result of the pickling process, which allows it to conduct electricity. Sodium (or other) ions within the pickle emit light as a result of atomic electron transitions, although it is not clear why the luminescence occurs at one end of the pickle. The glowing pickle is used to demonstrate ionic conduction and atomic emission in chemistry classes, and also as a demonstration in lighting classes. The first known fully documented demonstration was in a 1989 report from Digital Equipment Corporation. Although this was published as a full technical note and written up as a scientific paper, the publication date, April Fools' Day of that year, gives some indication as to the light-hearted nature of the document.

The Surprising Physics at Play Inside of a Glowing Pickle #SoME2
The glowing gherkin (pickle) seems to be a popular demonstration experiment for young students, as evidenced by the videos linked below, which are still just a small subset of all the youtube search results. However, not many people seem to address the fact, that usually, the gherkin is o

Why Pickles Make Great Light Bulbs
In this video I show you how a pickle can emit light when energized with 120VAC. I talk about the color produced and why it is the same color as a low pressure sodium vapor lamp. Then I try the same experiment with potassium hydroxide to see if the color can be more lavender then yellow.
