@the_mystery_vault: London built a bridge that nearly knocked everyone over 🌉 On June 10, 2000, London opened the Millennium Footbridge—and it immediately started swaying out of control! A strange phenomenon called "synchronous lateral excitation" forced people to adjust their steps to the movement, unintentionally amplifying the wobble. It closed two days later and needed 89 high-tech dampers to become safe 🛠️✨ #wobblybridge #london #engineering #physics #disaster #learnontiktok #history #mysteryvault #architecture
