Magic Egg Experiment

 Do you need a cool science experiment to do with your homeschooled kids or teens? Here is my personal favorite.

Fill a glass with apple cider vinegar and add in a single egg. Make sure the vinegar completely covers the egg. Soon you will see bubbles forming around the egg.

Normally bubbles are formed by pockets of air getting into the water. But with this experiment, the bubbles are caused by the vinegar reacting with the outer egg shell and releasing carbon dioxide. 

Leave your egg in the vinegar for at least twenty four hours. The vinegar will react and bind with the molecules in the egg shell and dissolve it. Only the outer membrane will remain. 

Now you can jiggle and play with your egg. If you break it open you will see that the inner yolk is still raw and preserved within the outer membrane.

Unfortunately the egg broke after I bounced it around too much but as you can see it formed a plastic outer casing that looks and feels like a popped balloon. It was very fun and squishy to play with before it broke.
