Take a raw egg and put it in a glass. Cover the egg with vinegar. Look at it a couple hours later and you will see bubbles all over the outside of the egg. This is a chemical reaction. The vinegar combines with the molecules of the egg shell to form a gas: carbon dioxide (CO2).
Change the vinegar twice a day. In a couple days the eggshell will be completely gone. What you have now is one giant cell! While most cells are microscopic, an egg is a type of cell that you can see without a microscope. Handle the egg gently and throw it away in a day as it will start to smell.

Anonymous, I can only imagine! Yikes.Peter, Lamaze. ha! No dolbue yolk in this one, but we do get those fairly often. And we are very spoiled by fresh eggs, it is true. I recently had some in a restaurant and I couldn’t eat more than a bite or two, they just tasted so blah.Mmm. Sounds good Chris. We don’t eat mayo too much, but maybe you can send me the recipe and I’ll try it. I had one somewhere but can’t find it.
