    My 6 year old son's favorite show is myth busters. So, we decided to to test a myth of our own. Do bad eggs sink in water? Well, we can tell you that fresh eggs float and that an egg left on the counter for over 4 weeks finally started to bob in the water a little. We don't have an old enough egg to see if it really floats yet. As we all know, fresh eggs last so much longer anyway when you don't wash them and all of that.

    So happy to be joining this forum. You guys are really funny and in such a wholesome way!

    Fresh eggs sink in the water, bad eggs will float, the reason is the older an egg, the larger the air cell gets. The more air in the egg, the more it will float.

    I hope this helps some and [​IMG]

    Love that show Mythbusters!

    Old eggs float - has to do with the larger air cell in the egg. My fresh eggs, smallest air cell, lay on their side on the bottom of the bowl of water.

    Quote:Frsh eggs sink. Medium old eggs bob under the surface. Old eggs float due to the bigger air cell at the big end.

    If you used store eggs as your "fresh" eggs in the test, it's an invalid test.

    Not ALL bad eggs float! I had some eggs that had been chillin my fridge for god knows how long, so I float tested them. A couple floated, and I tossed them. Several stood up, and I tossed them too. The rest were laying flat on the bottom. I started cracking and about puked when one of the eggs was pure green and the stench was awful! It had NOT floated....

    i was searching about this on google and found this. i took the time to create an account just to share my thoughts. i must say that there's no such thing as "air cells" air is a combination of different gases, a cell is a completely different thing.

    that is just plain stup1d.

    have a nice day.

    Thank you for your input Daniel. But I bet more people would be interested in what you had to say if you did not imply they were "stup1d". People are here to learn, not to be put down. Try using a filter next time, you might be pleasantly surprised by how your message is received.

    The air cell is a commonly used phrase used to describe the void or air space if you'd prefer in an egg. As an egg ages it loses moisture & the air cell or space enlarges.

    The air cell is a commonly used phrase used to describe the void or air space if you'd prefer in an egg. As an egg ages it loses moisture & the air cell or space enlarges. I don't think that anyone using the phrase air cell believes it to be a cell as in the sense of a microscopic biological unit. I believe your attempt to illustrate your erudition showed only your own limitations.

    Oh, to the OP, fresh eggs most certainly do not float.
