Good Egg…or Bad?

Ever wonder if the eggs you’re buying are fresh? Here’s how to tell.

At the large end of the egg, there is an air pocket about 1/8 deep and approximately as large around as a dime. As an egg ages, it loses both moisture and carbon dioxide causing the egg to shrink and the size of the air space to increase.  By placing an egg in water the size of that airspace determines the buoyancy of the egg – and its freshness.

  • When you submerge a fresh egg in water it will rest on the bottom.
  • An egg that is about a week old will bob slightly on the bottom.
  • At about three weeks old it will balance on its small end, with large end straight up.
  • A bad egg will float.
