This phenomenon is explained by density and Archimedes' principle. An object floats if the density of the fluid is greater than the object's density. A fresh egg has a density slightly higher than pure water, so it sinks.
When salt is dissolved in water, it increases the water's density. The density of saturated salty water becomes higher than the egg's density, providing a greater buoyant force, causing the egg to float.
The buoyant force is given by , where is the fluid density.
Final Answer: Higher density of the salty water
