21. The Dead Sea

The Dead Sea. You float instead of sinking which is awesome.

Factoid: The Dead Sea (Yam Hamelakh -- "The Salt Sea") is the lowest place on earth, roughly 1,300 feet below sea level. It is 34 miles long and varies between 11 miles and 2 miles in width. The Sea is 1,400 feet deep. People float effortlessly on the waters of the Dead Sea due to its concentration of minerals, which is the highest in the world.
