How to make Egg float on water

Ordinarily Eggs do not float on water. They sink. This is because the density of egg (1.031 g/cm3) is greater than that of water (≈ 1g/cm3). Objects will float in water if their density is less than 1 g/mL. Objects will sink in water if their density is greater than 1 g/mL.
Adding salt to water increases the water’s density thereby making the egg float on it.
