Myth: A Floating Egg Is Bad
Many home cooks drop an egg in water and toss it if it floats, sure that means spoiled. Floating usually just signals an older egg, not a spoiled one.

Why Eggs Float As They Age
Eggshells are porous. Over weeks, moisture slips out and the air cell inside grows, so an older egg becomes buoyant enough to float in water.

Read The Angle, Not Just Float Or Sink
A very fresh egg sinks and lies flat on its side. As it ages it tilts up and stands on end while still touching the bottom, and only once it is old enough does it rise and float, so the angle in the water is a rough age gauge, not a single pass or fail line.

The Real Test Is Smell
Crack the egg into a bowl first. A spoiled egg has an unmistakable off odor, raw or cooked, and that smell, not floating, is the real warning sign.

Store Cold, Not In The Door
Iowa State Extension advises keeping eggs in their carton on an inside shelf at or below 40F, since the door swings in temperature far more.
