Have you ever wondered if those eggs that have been sitting in your fridge for weeks are still fresh enough to eat!? You don't have to wonder anymore thanks to this super easy egg freshness test in water!

The best thing about this method of testing your eggs is that you only need a few very simple supplies you already have at home to do it.

Supplies Needed:
Large Bowl or Tall Glass
Water
Fresh Egg
Old Egg (2-4 weeks old)
Very Old Egg (4-6+ weeks old)

How to know if an egg is fresh:

If the egg sinks to the bottom of the water and lays on its side, then the egg is fresh and good to eat.

If the egg sinks to the bottom but stands up on one end in the water, it is starting to get a little bit older, but the egg is still okay to eat.

If the egg floats to the top of the water then it too old to eat and should be thrown out!

This is because all eggs have a little pocket of air inside of them. This pocket of air is very small in fresh eggs, but the pocket of air will start to get bigger as the eggs get older.

With the small pocket of air inside the fresh egg, the density of the egg is still greater than the density of water so it will sink to the bottom of the water. This is why a sinking egg is a sign of a good, fresh egg!
