So, how do you know if your eggs are still okay? Forget the calendar. Use the float test. It’s the party trick of kitchen science, and it works every single time. Fill a bowl with cold water and gently place an egg inside.
If it sinks and lies flat on its side, you’ve hit the jackpot. That egg is supremely fresh. If it stands upright on the bottom but still sinks, it’s older but still perfectly fine for eating. If it floats to the top like a little submarine? Then you say goodbye, my friend. That one goes in the trash.
Why the Float Test Works (The Fun Part)
Eggshells are porous, like tiny sponges. Over time, air seeps in through those tiny holes, and the little air pocket inside gets bigger. A fresh egg is dense and sinks. An old egg has too much air and becomes buoyant. It’s nature’s way of telling you the story of that egg’s life.
I call it the “egg wisdom” test. It never lies, and it makes you feel like a kitchen wizard. My grandmother taught it to me, and she never threw away an egg based on a date stamp.
