Why is it impossible to sink in the Dead Sea? The reason is
that, not only is the water in the Dead Sea heavier than ocean water and much
heavier than fresh water, but it is also heavier than a person’s body, when
equal parts are measured. You can’t sink in something that is heavier than you
are. The reason for the heaviness is extreme saltiness. Are there materials
that would sink in the Dead Sea? Yes, and I’ll bet that you can think of some.
