No Rock to Hold Onto - Why the Burj Khalifa Hasn't Collapsed Yet

828 meters tall, half a million tons of concrete, and not a single piece of solid bedrock underneath to hold it... While standard skyscrapers anchor directly into solid rock, how does the tallest tower on Earth stand upright on loose desert sand and corrosive saltwater without sinking? In this documentary breakdown, we uncover the hidden engineering genius behind modern history's most extreme construction project. From pouring ice-chilled concrete in the dead of night to pushing an entire steel spire through the roof like a giant telescope, discover the seven seemingly impossible puzzles engineers had to solve to reach the stratosphere. Which engineering trick surprised you the most? And if you were given the chance right now, would you ever dare step onto that tiny steel platform at the absolute summit of the spire?
