At Oxford University, a tiny bell has been quietly defying time for nearly two centuries. Known as the Oxford Electric Bell (or the Clarendon Dry Pile), this mysterious device has been running continuously since the 1840s, powered by one of the world’s oldest batteries. Scientists still don’t fully know how it works, or how it’s lasted this long.Why has this bell never stopped? What makes its unknown battery chemistry so enduring? And what does it reveal about the history of science, electricity, and human curiosity?Gordy dives into one of history’s strangest and most enduring scientific mysteries—an experiment that has outlasted the Victorian era, the telegraph, and even the invention of the lightbulb.Stay tuned—this story is a reminder that sometimes the simplest experiments can outlast entire generations.SourcesDibner, B.
