Place the egg into a bowl of cold water.

The water level should be about 2 times higher than the egg.

Observe what the egg does;


  • Sinks? … … then it’s Fresh! 
    Fresh eggs will sink to the bottom of the bowl, and probably lie on their sides.
  • lies on the bottom but bob slightly … … 
    = about one week old.
  • Balances on its smallest tip, with the large tip reaching for the top,
    = it’s probably close to three weeks old.
  • Floats at surface?
    it’s bad and should not be consumed!


Why this works? Bad-Eggs-Float

Eggshells are very porous, and an egg’s shelf life diminishes as more air enters the shell. The more air that enters the shell, the more buoyant the egg becomes.
