The girl to the left is actually floating in the Dead Sea. "But, hey, I thought you said the Dead Sea was DEADLY!" Not to us. Humans are remarkably adaptable. We can swim in the Dead Sea, just like we can swim in the ocean. Well, people don't really "swim" in the Dead Sea - they just "hang out". That's what's so cool about the Dead Sea. Because of the extremely high concentration of dissolved mineral salts in the water its density is way more than that of plain old fresh water. What this means is our bodies are more buoyant in the Dead Sea - so you bob like a cork. In fact, people are so buoyant in this water, it makes it kinda tough to actually swim. Most people like to just kick back in the water and read. It almost looks as though this lass is sitting on an air mattress that has sunk below the surface, but she's not. She's really just floating, without having to hold her feet in that position! If you think this is easy, try floating like this in a freshwater swimming pool.
