QT:{{”
A chicken’s egg is covered in a shell that is made of calcium carbonate. That’s a complex arrangement of carbons, calcium, and oxygen. Regular vinegar is made of acetic acid. You all know when you mix vinegar and baking soda what a strong reaction you get. The shell is made of the same “carbonate” and will react like soda, only much less extreme. The little bubbles you see in the water are made of carbon dioxide gas; just like the bubbles from your vinegar and baking soda volcano.
Once the shell is gone, the vinegar will cross over the semi-permeable membrane (through a process called “osmosis”) and slightly inflate the egg. This process also “pickles” the egg, by hardening it up. The toughening of that membrane is what lets you bounce it on the counter, roll it along the floor, and whatever trickery (I mean science) you want to do with it!
