The Bouncy Egg

Today my daughter and I started the Bouncy Egg experiment.  Before setting it up we talked about eggs and what happens to them when dropped.  Guess what?  They break, making a big mess!  If you put the egg in vinegar for a few days, however, the egg yolk will bounce, or so I'm told.  Details and procedure are found here:

It's a three day experiment that begins with putting the egg in vinegar.  Here's our egg:

That's it for the first day.  You see the egg covered in bubbles and the lid of our jar made a cool "pop" sound after a couple of minutes.  Tomorrow we replace the vinegar and wait another 2 days.  On Friday we should have a bouncing egg!  We're both excited!
