Does sea salt make things float?

Yes, sea salt can make things float because it is denser than water. When an object is placed in water, it displaces an equal volume of water.

If the object is denser than water, it will displace its own weight in water and sink. If the object is less dense than water, it will displace more than its own weight in water and float.

Sea salt is denser than water, so it will sink in water. However, if you dissolve enough salt in water, it will create a salt solution that is denser than pure water. This is because the salt molecules displace water molecules, which makes the solution more dense.

If you place an object in a salt solution that is denser than pure water, it will displace less than its own weight in water and float. This is why things float in the Dead Sea, which is a salt lake. The Dead Sea is about 34% salt, which is much saltier than the ocean. This makes the Dead Sea so dense that it is difficult to sink in it.
