Explanation of Simple Experiments; Floating Eggs in Water

When placed in water, raw eggs with good conditions have a density greater than fresh water, causing the eggs to sink. When you add salt to the water, the mass of the water changes, causing the eggs to float. The higher the egg floats to the surface, the more salt you apply.

The egg has a watertight section and is totally filled with air, so as long as water does not enter the egg body, it will not sink. This is also consistent with what occurred with ships. Ships have an air-filled hull that prevents them from sinking as long as water does not penetrate that portion. Furthermore, the density of saline seawater makes it easier for ships to float on water’s surface.
