King Fahd's Fountain, Jeddah, Saudi Arabia
This impressive fountain shoots a stream of water from the Red Sea to a point that is nearly 1,000 feet in the air. The saltwater jet is propelled upward at a speed that can reach more than 200 miles per hour. The water used for the fountain comes directly from the Red Sea, so no fresh water is wasted. Estimates suggest that if you measured the total amount of water that was in the air at any given moment, the weight would equal about 18 tons.
This fountain is visible from all over the city of Jeddah, which is the commercial capital of Saudi Arabia, so you will surely see it, even if you aren't exactly looking for it. Lights illuminate the jet of water at night.
