Eggs-Ray Eggs




With a bit of chemistry know how, you can dissolve the shell from an egg as if you had x-ray vision. This is no yolk.



A couple of raw eggs White vinegar (at least two cups) A couple of clear glasses or jars



Carefully place an egg in the glasses or jars and fill the them with vinegar so that the eggs are completely submerged. 

Wait 12 to 24 hours until most of the egg shell has dissolved away. Carefully pour out the liquid from the glass/jar so you can catch the egg in your hand. You can rub the remaining bits of the egg with your fingers. It will be like a white powder. If the shell is not coming off easily, return the egg to the glass/jar with fresh vinegar.

After the first or second soaking in the vinegar, you will notice that the egg, held together with membranes, is still pretty much intact. 

Why it works:


Egg shells are primarily composed of calcium carbonate. The primary material found in pearls and seashells. When you put the egg in the vinegar, which is around 4% acetic acid, you cause a chemical reaction that results in calcium acetate, water, carbon dioxide gas, and a strange looking egg.


Amazing applications:


Did Cleopatra win a bet with Mark Antony by drinking a pearl dissolved in vinegar? The story, originally written by Pliny the Elder around 77 BC, described a challenge issued by Cleopatra that she could eat the more extravagant meal to the tune of $30 million dollars based on the current value of gold. The story goes that she won the bet by dropping a valuable pearl in a glass of vinegar at the end of the gourmet banquet. Was this a true story? Well, chemistry has proven that the acetic acid in vinegar will dissolve the calcium carbonate in the pearl. It just takes time. As for the Cleopatra’s story, it’s a great source of debate between historians.
