A pickle glowing when an electric current is passed through it

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.[1]

The glowing pickle is used to demonstrate ionic conduction and atomic emission in chemistry classes,[2] and also as a demonstration in lighting classes.[3]
