Do you know this trick? Here’s a quick and easy way to tell if an egg is fresh or expired: Submerge it in a glass of water and salt. If it floats, the egg is expired; if it sinks to the bottom, it’s fresh!
Why it works
The floating test works by changing the egg’s internal structure over time. As eggs get older, air penetrates through the porous shell, creating a larger air cell. This increased buoyancy causes older eggs to float while fresher ones stay underwater.
