With the 2009 opening of the Dubai Fountain, featured in today"s image, the city of Dubai claimed another record for the books—"world"s tallest performing fountain.’ It"s located appropriately enough at the foot of the Burj Khalifa, currently the world"s tallest building. Designed by the same company that created the fountains at the Bellagio Hotel in Las Vegas, everything about the Dubai Fountain is impressive. Over 900 feet long and located in the 30-acre Burj Lake, the fountain has more than 6,600 lights and 75 color projectors. These are used to create over 1,000 different "water expressions" and provide a rainbow of colors, all perfectly choreographed to a carefully crafted musical playlist.
