Are Those Eggs Still Good To Use?

I found this on Tip Junkie today and thought I would share. I am always wondering if my out dated eggs are still good to eat or cook with.

Ever have an egg in your fridge and you were not sure if it was still good or not? There is an EASY way to find out. As eggs go bad, gases are produced inside the egg. As those gases are produced, the egg becomes more and more buoyant.
Here’s what you do!
Fill a glass with water, place your egg inside.
If the egg sinks to the bottom, it is still good and will be for some time.
If the egg floats to the middle of the glass, it is still good but needs to be used soon.
If the egg floats all the way to the top, you need to throw it away.
I swear knowing this is going to really impress someone at some point in your life.
