Why is it impossible to sink in the dead sea?

Answer 1: Because the amount of salt in the red sea makes it much more dense its like dropping a sultana in a glass of lemonade then dropping one in porridge Answer 2: There is an extremely high salt composition in the water that makes it more dense, this allows heavier objects to float on its surface. When a liquid is more dense, it means the particles are pact closer together. A better example would be trying to float in water, vs. trying to float in thick cement, the water is flowing and will let a body pass through it, as the cement is more dense it does not let objects pass through it as easily.
