As the time passes , egg will decompose by itself . Because of this , mass of egg is reduced as egg shell is porous and inner vapour content will escape to atmosphere .
This reduces the mass of egg . If this egg is put into water , the volume of water displaced by this egg is more than its own mass . Hence it will float .
