Did you know the Ferris wheel, brownies, and even the zipper all debuted at the 1893 Chicago World’s Fair? This event was basically the OG tech expo—introducing popcorn machines, electric lights, and even the first picture postcards. Houdini performed, Helen Keller showed up, and Pabst Blue Ribbon got its famous name. Next time you eat a hot dog or ride a moving sidewalk, thank this wild fair for shaping modern life! #News #HistoryNerd #FunFacts
