This easy test takes just seconds but offers peace of mind.
Why This Trick Works
As eggs age, moisture evaporates through their porous shells and the internal air cell expands.
A fresh egg is dense and sinks.
An older egg stands upright or floats due to the larger air pocket.
It’s a simple application of basic physics and chemistry.
Other Methods for Checking Egg Freshness
While Nana’s water test is the easiest, there are a few other methods:
Candling: Shining a light through the egg to check the air cell (used by farmers).
Crack Test: Fresh eggs have firm yolks and thick whites.
Shake Test: If you hear sloshing when shaking, the egg is likely old.
