Question

why do we float in dead sea

Answer 1

"The Dead Sea's unusually high salt concentration means that people can easily float in the Dead Sea due to natural buoyancy. In this respect the Dead Sea is similar to the Great Salt Lake in Utah in the United States. 5. The Dead Sea is roughly 8.6 times saltier than the ocean."

Answer 2

We can easily float in dead sea because dead sea has salty water and denser than that of normal water which makes people easy to float into it.
