If eggs float are they off?

Yes, if an egg floats in water, it is likely spoiled or "off." Here's why:

* Air Pockets: As eggs age, the yolk and white break down. This creates air pockets inside the egg, making it less dense.

* Buoyancy: The air pockets increase the egg's volume, making it less dense than water. This allows it to float.

However, there are a couple of caveats:

* Freshly Laid Eggs: Some freshly laid eggs might have a small air pocket and could float briefly.

* Salt Water: Eggs will float more easily in salt water due to its higher density.

The best way to determine if an egg is off:

* Crack it open: The best way to be sure is to crack the egg and smell and visually inspect it. A fresh egg will have a mild odor, and the yolk and white will be firm. A spoiled egg will have a strong odor and the yolk and white will be watery or discolored.

Bottom Line: While a floating egg is a strong indicator of spoilage, it's not always foolproof. Cracking it open is the only way to be absolutely sure.
