Explanation
  1. A body floats if its density is lesser than the density of the liquid.
    Density of egg is greater than density of pure water. So, it remains at the bottom. But when salt is added the density of salt water becomes more than density of egg. So, the egg rises and floats.
    1. The outer layer of egg is impermeable to water.
