It’s called the “Dead Sea” because the salt content isn’t exactly welcoming for underwater life – it’s one of the world’s saltiest bodies of water (33% saltine). Due to the hypersalination of the water, you can float!
In this photos from the Dead Sea on the Jordan side, I have both hands and feet out of the water as I float. I found a newspaper for the photo but it was just a prop. Look closely and you’ll see I’m reading a Japanese newspaper!
