Eggs Freshness Test
I eat too many eggs for them to ever go bad, but this sure is good to know. I got so excited when I saw this, I dug into my fridge to test it for myself. My eggs seemed to be 4-6 days old — good enough! You’re probably wondering how this works, and yes, there is some science behind it. Eggshells are porous, allowing air to slowly get in over time. As more air enters the egg, it gets lighter and lighter, which explains why it will eventually float.
