We've all heard that the United Arab Emirates has been hard at work constructing the world's tallest building. The Burj Dubai currently stands 159 stories tall, and will include 30,000 homes, 9 hotels, 19 residential towers, and the Dubai Mall. The entire project is estimated to cost $20B, but that's hardly the only thing the UAE likes supersized. Here are a few other records the tiny nation holds:

World's Largest Flag

On UAE National Day, a 50,000 square feet flag flew over Abu Dhabi, forming the largest aerial banner ever flown.
