Electric Pickle

Glowing pickle demonstration

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.‍ The pickle only glows at the bottom end because it is where the brine collects. The glowing pickle is used to demonstrate ionic conduction and atomic emission in chemistry classes,‍ and also as a demonstration in lighting classes.‍

Electricity

Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.
