The World's Longest-Running Lab Experiment Is Almost 100 Years Old
Summary
The ScienceAlert piece describes the Pitch Drop Experiment started in 1927 at the University of Queensland, where pitch—though seemingly solid—drips extremely slowly into a beaker. After 96 years, only nine droplets have fallen, with the last observed in 2014; scientists expect another drop in the 2020s. The experiment exemplifies the longevity of scientific inquiry and the educational value of long-term data collection.
