Funny Experiment With Egg And Vinegar
When you soak a raw egg into a vinegar over two days, the vinegar will dissolve the eggshell. Eggshell is mostly made up of Calcuim carbonate and that is the reason it is hard and vinegar contains acetic acid. So when vinegar gets mixed with the egg, the acetic acid which is present in the vinegar dissolves the shell of the egg and the egg becomes elastic. The egg turns out to be a funny one which looks like a Jelly. And if you do this same experiment with a boiled egg, the shell gets dissolved and the egg becomes elastic like a rubber ball.
In this picture you can see that an egg is being kept inside a jar filled with vinegar.

Pour 9 % of vinegar into a transparent glass and place the egg inside the glass. You will find that there is carbon dioxide formed immediately on the surface of the egg.

90 % of the shell of a birds egg is of Calcuim Carbonate and when the interaction takes place with the acid, the shell begins to disintegrate releasing CO2. After 12 to 15 hours you can see that the calcuim carbonate from the surface of the egg gets disappeared and only a film between the surface and the egg remains intact.

Then Remove the egg from the glass of vinegar and rinse the egg under the running water.
