salt water
No, a raw egg can not float in salt water, but if you hard boil it will because it is denser and therefor becomes more buoyant.
If the egg was raw then the inside would shrivel up due to osmosis.
When a raw egg is placed in a saltwater solution, osmosis occurs. The salt concentration outside the egg is higher than inside the egg, so water moves out of the egg to try to balance the concentration. This causes the egg to shrink and become dehydrated.
The density of an egg that I boiled was 1.02 * density of tap water. The density of a raw egg was 1.06 * the density of tap water. The mass of the egg did not change so the volume increased slightly. With a raw egg and a boiled egg covering in water, if you add salt and mix slowly you find that the boiled egg will float first and if you continue to add salt you get both to float. Interestingly, recipes for making a brine solution for food preparation frequently tell you to put a raw egg in water and add enough salt in solution to make the egg float. This assures enough salt for a good brine solution.
Yes.
Yes, a raw egg will float if the salt concentration is high enough. This is possible because adding salt creates a solution with a greater density than water. As more salt is added, the density of the solution increases. At a certain point, the density of the solution becomes greater than the density of the raw egg, allowing the egg to float in the solution.*This experiment is a very good demonstration of the principle of buoyancy.
When you put a raw egg in vinegar, the acid in the vinegar dissolves the eggshell. This leaves you with just the egg membrane. When you then place the egg in saltwater, osmosis occurs where water moves from the egg to the saltwater or vice versa depending on the concentration gradient, causing the egg to shrink or swell.

No it does not have to be raw or boiled fo rthe egg to float!
To make an egg float in salt water, you will need a raw egg, a container filled with water, and salt. By progressively adding salt to the water and stirring until the egg floats, you can achieve this simple science experiment.
