Glowing Electrocuted Pickle Explained: Sodium Spark Makes It Shine
Original: A Pickle Plugged Into an Outlet Glows Like a Tiny Star. Now We Know Why.
Scientists have explained why a pickle plugged into household electricity glows like a tiny star. When current passes through the pickle, it heats and arcs across the sodium-rich interior, exciting sodium atoms whose electrons emit bright yellow-orange light on the same wavelength as sodium street lamps. The effect is a staple classroom demonstration and has now been studied in detail.
Why now: A new explanation or study of the classic glowing pickle experiment has drawn fresh attention to a familiar science demonstration.
