Did you know you can remove the hard shell of an egg by simply soaking the egg in vinegar? It is so cool! This is your classic acid/base chemical reaction. The egg shell is basically made of calcium carbonate. The vinegar, containing acetic acid, separates the calcium and releases the carbonate as carbon dioxide gas. You can see all the bubbles of gas in the picture below. These bubbles started happening immediately.
After soaking for about 2 days, the shell has completely dissolved away and you are left with a translucent egg. You can't tell by the picture, but you can even see the egg yolk inside.
Now you would think that the egg would be fragile without the loving protection of its hard outer shell. Not so! This sucker is durable. It has the consistency of a rubber bouncy ball. You can see in the pictures below that I'm squeezing the egg pretty hard. Next up...to cut it open and see what it looks like inside!
