The incredible bouncing egg

Bouncing Egg?
Have you ever tried this?  This is so cool

 

All you need is a egg , vinegar, and a jar.

You place the egg in the jar and cover it with vinegar just enough to cover it.  

Next refrigerate 1-2 days.

Gently rinse under running water, while rubbing it to remove the shell.

Notice you can see the yoke when you hold it up to a light? 

The egg is squishy and bouncy.  

Note: you still have to be gentle or you could pop the egg.  

We gently bounced it, rolled it, and squished it.  

Very neat experiment.
