This is a pretty cool experiment that uses only a few items, but provides a fascinating result. An egg is a perfect example of one animal cell that you can actually study without a microscope, plus who does not want to see what an uncooked, unbroken egg would look like sans shell...
If you ever wondered, here is the way to do it. :)
Materials: One egg, a glass container to hold it, and enough vinager to submerge the whole egg.
Place egg in the container. Cover it with vinager. Wait for a few days (you can place it in the refrigerator if you want).
This is what is going to look like:
Enjoy! Handle with care, and discard after you are done. You definitely do not want to make an poached egg with this one :)
