Bouncy Egg<br />
Between the vinegar and eggshell, a chemical reaction occurs. The acid in<br />
the vinegar reacts with the calcium carbon<strong>at</strong>e in the eggshell. This<br />
reaction breaks down the eggshell. The reaction also makes carbon<br />
dioxide and if you look <strong>at</strong> the egg carefully you will see bubbles on the<br />
eggshell as it is reacting with the vinegar. The membrane underne<strong>at</strong>h<br />
does not react, and it will be left once all the eggshell has gone, making<br />
the egg bouncy. It is very delic<strong>at</strong>e and will break if you prod it <strong>to</strong>o much.<br />
