Much to the delight of (most of) the class, when we observed our eggs this afternoon they had become soft, squishy and rubbery.

| The Eggs Felt Like They Were Made Of Rubber Today! |
The egg shells were dissolved by the vinegar. The acetic acid broke apart the calcium carbonate crystals in the egg shell. The bubbles we observed was actually the calcium carbonate being carried away from the egg.
 |
| Eggs and Vinegar Don't Always Smell Very Pleasant The students decided to extend the experiment even further. We cut one of the rubbery aggs in half, we left two out of the vinegar overnight, and we left two in the vinegar for another night. We wonder what the eggs will be like tomorrow? |
