how to peel a egg raw

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