In ancient times, entertainment was scarce. One fascinating example is a unique wine cup with a concave bottom. When wine is poured into it, the cup wobbles and dances gracefully without toppling or breaking apart. In a modern study, a non-destructive method—captured in MP4 format—can be employed using a digital microscope. This allows researchers to analyze trapped air bubbles, black specks, and other impurities. By measuring and plotting their diameters in Excel, comparisons can be drawn across different imperial reigns.
