Some of the world’s most famous structures hide incredible secrets! The Sphere in Las Vegas has a sound system so precise it can deliver audio directly to individual seats without disturbing others. The Gateway Arch in St. Louis doubles as a time capsule, holding documents from the 1960s for future generations to discover. Dubai’s Burj Khalifa sways up to 1.5 meters at the top to withstand winds and even recycles condensation to water its gardens. The Sydney Opera House, inspired by orange peels, has “acoustic clouds” on its ceilings to perfect sound quality. These hidden features make these landmarks even more amazing than they appear!
