How to Tell If Eggs Are Fresh

Do you know this trick? Here’s a quick and easy way to determine if an egg is fresh or expired: immerse it in a glass of water with salt. If it floats, the egg is expired; if it sinks to the bottom, it’s fresh!

Why This Works
The floating test works due to the changes in the egg’s internal structure over time. As eggs age, air enters through the porous shell, creating a larger air cell. This increased buoyancy causes older eggs to float, while fresher eggs remain submerged.
