You will need the following:
Place the egg in the glass or jar and cover it with vinegar. You will see that the shell, which is mainly composed of calcium carbonate, reacts with the vinegar and starts to disintegrate. As this happens, carbon dioxide is released as bubbles.
You can see the acidic vinegar dissolving the egg shell and the egg becoming elastic. The egg behaves as though it were made of rubber!
When you compare the vinegared egg with an ordinary one, you’ll see that the former is noticeably larger.
Remember!!! After the experiment, the egg is no longer edible!
