The Dead Sea is made up of 35 percent salt, making it 10 times saltier than the ocean. This high salinity makes the water very dense — denser than even your body — which causes you to float. It also makes the water feel almost oily and not at all like the beach water you're used to. Because you can float, you'll see many people with books or newspapers floating comfortably in the water while they read.
If you're craving a float experience, there are specialty spas that re-create this effect. They're actually pretty trendy right now, so search "float spa" in your area and you'll likely be able to find one nearby. They're especially popular among athletes, as floating creates a sense of low-gravity, thereby relieving pressure from bones and joints. Another natural option is Utah's Great Salt Lake.
