Scientific demo involving electrocution of pickles
A pickle glowing when an electric current is passed through it
Applying electric current across a pickle causes it to glow. A moist pickle contains salt as a result of the pickling process, which allows it to conduct electricity. Ions of sodium and other substances 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]
The first known fully documented demonstration was in a 1989 report from Digital Equipment Corporation.[4] 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.
