Easter Egg Geodes

We love science experiments in our house!  When I saw that you can make your own Easter Egg Geodes, I had to try it!  I think they turned out beautifully!!

Just save some egg shells when you cook.  This is best if you break the egg at the top, leaving as much shell as you can.  Then, wash out the inside of the shell completely even making sure to remove the membrane (this part is the hardest part-it was kind of a pain in the butt).  If you don’t get the membrane out you could get mold instead of crystals.  Yes, that would still be a science experiment, but not one I care to do! ;)
Next you just boil up batches of water (I used 1/2 C at a time because I just wanted to fill up one egg with each substance and have lots of colors) and anything that dissolves in water.  Some examples to try are epsom salt, sea salt, sugar, cream of tartar, table salt, etc!  It is fun to guess which substances will grow crystals.  You want to put as much of your substance as will dissolve completely into the boiling water.
 
Then, you add food coloring and then fill the eggs up as much as you can.  Just let these puppies sit and the above picture is what happened with ours.  This will take days.

It was fun to see designs starting to appear on the outside of the egg.  When I heard about this experiment, the crystals are supposed to be more inside of the egg then outside. 
 
However, we got most of our crystals on the outside of our eggs.  I am no science nut so I do not know why this is.  I’m sure there is a reason, though.
 
We loved seeing them on the outside though!  Look how cool this blue egg turned out!  It reminds me of those sugar eggs you look into.

This orange one had crystals that looked more like snowflakes!
   
This was really a fun experiment that my kids and I enjoyed doing together!  I’d love to see how anybody else’s turn out!
