Naked Eggs

Last week after making Elephant Toothpaste, Finn started a batch of naked eggs. We put a raw egg in a cup of vinegar, changed it out after 24 hours and then let it sit for a week. The egg above is raw, but the vinegar dissolved the shell in an acid-base reaction. The membrane remained in tact and we could handle it and even drop it from a small height.

In the end Finn proved to us the egg was indeed raw by dropping it and shattering the delicate membrane. Very cool!
