how to peel a egg raw

Experiment no 1: to make egg shell disasppear
materials needed : white vinegar,egg,glass jar, lid

1.  Add egg to glass jar.
2.Pour vinegar to jar until egg sinks completely. Tiny bubbles of carbon dioxide gas  start to appear on the eggshell after just a few moments.
3.wait for chemical reaction to complete (few days/week)
4.remove egg from vinegar and wash off remains.

This is a acid-base reaction. Vinegar contains acetic acid. Eggshells contain calcium carbonate(base).

The calcium carbonate in the eggshell reacts with the acetic acid in the vinegar to form a water-soluable compound, calcium acetate, and carbon dioxide (CO2) gas. This reaction dissolves the eggshell, but leaves the inner membrane intact, creating a naked egg.
