salty
An egg is one such thing.
An egg will sink in fresh water. Salt water is denser than fresh water, which allows the egg to float.
eggs float better with water and salt but they do not float in just water
The egg should have its water or substance in the egg come out through the cell membrane. :)
Fresh eggs float in salt water because the density of salt water is more than the density of the egg. But fresh eggs do not float in fresh water because the density of water is less than that of the egg. Salt increases the density of water.
salt water
Eggs float in salt water but not in tap water, which is a fresh water. This is because salt water is more dense than fresh water.
An egg that sinks in water is fresh, while an egg that floats is not fresh.

It depends on the age of the egg. An older egg is likely to float as the air bubble in the egg hows larger as the egg dries out. This used to be a test for separating fresh from old eggs in general stores. Even a fresh egg (even though it doesn't float) will orient itself bubble end up in a pan of water.

There is an small air space in eggs. The space is too small to let the egg float in fresh water. An addled egg may have formed enough gas, due to decomposition, to cause the egg to float.
salt water
The older an egg is the more likely it is to float. If it actually sits on the surface it may actually have gone bad.
In a denser liquid.A raw egg will sink in fresh water, but float in salt water. It also depends on how fresh the egg is.Set an egg in cold water-If the egg stay at the bottom - it is fresh.If the egg is at an angle on the bottom - it is still fresh and good to eat.If the egg stands on its pointed end at the bottom - it is still safe to eat but best used for baking or boiled eggs.If the egg floats - it is best discarded.
