@Spitzspot yeah I dunno why exactly the Pitch Drop experiment gets the label “longest continually-running experiment”. Probably some kind of technicality about what exactly counts as “experiment” and “continually-running”. There are some even older than Beal’s listed on Wikipedia, depending on how you define it. https://en.wikipedia.org/wiki/Long-term_experiment
