The eggshell does more than soften -- it vanishes!
The shell of an egg is made of calcium carbonate. If you drop an egg into vinegar, the shell begins to dissolve slowly. Eventually, the shell will dissolve completely, leaving behind the egg's membrane, which is soft and pliable. It looks for all the world as though the shell itself has grown soft, but in reality, what you are seeing is an intact egg from which the shell has been dissolved away.

DESCRIPTION : A chicken's egg is enclosed by a shell that has a high calcium content. If a raw egg (shell still intact) is placed in a glass of vinegar, a reaction (RXN) takes place. The acetic acid in the vinegar will dissolve the eggshell and the egg will bounce. The reaction will begin immediately when the egg is placed in the vinegar but will not be complete for two or three days. After two or three days, the egg will survive a drop of four to five inches.

The chemical in vinegar is acetic acid (a weak acid). Egg shells are made of calcium carbonate, another chemical compound. When these two substances react, carbon dioxide bubbles form from the carbonate and the egg shell disappears.

the egg shell sucks upm the vinegar and the chemicals in the vinigar kills the cells that makes the egg shell hard n thats wen it becomes soft

VINEGAR is ACIDIC and acid takes things apart, molecule by molecule, that's why your mother said," Eat an apple a day to keep the doctor away."

vinegar=95% acid and 5%water
the acid breaks down the shell

viniger is acidic, and assuming that something in the egg is a metal, it would soften in because acids react with metals and break them down. or the egg could be made of a base, and when bases and acids reasc they become neutral.

because the vinegar disolves the calcium in the egg shell.
This also works on a chicken bone- we did it in high school science class!

the vinegar is acidic
i think you can also add food coloring and it will turn that color by absorbing it
