Nana’s method is wonderfully simple:
Drop the egg into a bowl of water and watch what happens.
As eggs age, a tiny air pocket inside grows larger. This natural change affects how the egg behaves in water, giving you a quick and clear indicator of its freshness.
Step-by-Step Guide: How to Do Nana’s Water Test
Fill a bowl with cold water deep enough to submerge the egg.
Gently place the egg into the water.
Observe its behavior:
Sinks and lays flat on the bottom: Very fresh.
Sinks but stands upright: Still safe, but use it soon.
Floats to the top: No longer fresh—discard it.
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.
