Why do old eggs float while fresh ones sink?

3 months ago
25

This video explains the science behind the egg float test. As eggs age, air enters through the porous shell, forming a larger air cell. This decreases the egg’s density, making old eggs float in water. Fresh eggs sink because they are denser and contain minimal air. Learn how to test egg freshness using water—backed by real food science and USDA research.
