Extraordinary Eggs

I did this science experiment with my kids... they loved the result!

Put an egg in a cup and cover it completely with vinegar.  Leave it for a few days and the eggshell will become soft...

 Day 1:

Day 2:

Day 3:

The shell has become soft because the vinegar has drawn all the calcium out of the shell.

More great science experiments can be found in this book (link under image).
