Dubai’s Burj Khalifa is currently the tallest building in the world, which measures merely 2,716.5 feet in height.
The Pearl, set in Hong Kong, doesn’t exist, but if it were, it would be even taller than Burj Khalifa, being 3,500 feet tall with 240 floors.
Watching it will take your breath away, especially to those who are afraid of heights.
