They don't.
Yes any salt can make things float
salt makes the water denser, so things that are now less dense than the salt water will float
not exactly. things that are less dense than water float. salt makes water more dense and therefore more things can float in it. ============================= (Notice that your rubber duckie floats in the bathtub, even though t here's no salt in your bath.)
the salt makes the water denser
Salt water is denser than fresh (not salt) water.
dawdadawdawd yes
Whether things float or sink this depend only on the density , the density of the salt water is aprox. 1030 kilogram per meter cube so if you but things have density less than that they will float , things with higher density sink.
It makes the water more dense.
because th salt makes things float and George bush was the worst president
An egg is one such thing.
density
Because it is full of dissolved salt which makes the density of things lighter, and therefore makes them float.
