This is the classic trick. Fill a bowl with cold water and gently drop your egg in. Watch closely—this is where the drama unfolds.
A fresh egg will sink like a rock and lie flat on its side. It’s heavy, dense, and full of liquid life. But an older egg? It will stand up on one end, like a tiny submarine periscope.
If it floats to the top? Abandon ship! That egg is officially a fossil. Toss it. The science? Eggshells are porous. As the egg ages, it loses moisture, and air seeps in. More air = more float.
Shake, Rattle, and Roll
Hold the egg up to your ear. Give it a gentle shake. Listen closely. A fresh egg will be silent as a ninja. The yolk is snug and secure inside.
But if you hear a slosh or a rattle? That’s the sound of regret. The yolk has shriveled, and the white has thinned. It’s not dangerous yet, but it’s past its prime.
Think of it like a handshake. A firm, steady egg is polite. A loose, jiggly egg is awkward. You don’t want that in your omelet.
