Because this kind of eggs are generally not preserved, the carbon dioxide in the eggs caused by the long storage time will penetrate from the egg shell, and the egg yolk and protein will slowly shrink, so it will cause the gas chamber to become larger. Therefore, the activity space of the egg liquid will become larger, and the sound of shaking is obvious.
