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!

That does look fun! How long do you have to wait before crystals form?

How cool!!

Stefanie said...

Love it. How long did it take?

This will take days. I did mine last Friday and by Monday or Tuesday I think they were pretty much done growing. Though lots happens immediately.

How fun! I will definitely have to remember this one when my kids are older. I know my husband would enjoy it now, though! Have a great weekend!

Now that looks fun!! Thank you for sharing and bringing your hodgepodge to my party. I love seeing what you are up to. Hope to see you again.

My husband (We're chemistry majors) was tring to do something similar with our 5 year old (not with eggs...just dissolving salt and waiting for the water to evaporate...and our 2 year old dumped it out just today. I think we'll try it again with the eggs. It looks a lot more fun this way.

It's quite common for the salts to "creep" out of the solution. It has to do with capillary action. Basically the attractive forces (polar water molecules attracted to the glass and to the ionic salts that have deposited already) in the water solution pull a bit of the solution up the walls of the container. (This is also why when you look at the surface of water, it is curved just a tiny bit at the sides.) It only draws a tiny bit of water up, though, and when that tiny bit dissolves, it deposits the salts it carried with it. Then it keeps on repeating, making the salt crystals "creep" farther and farther. It also looks like you may have some creeping caused by the same principles through the pores in the egg. Anyway, thanks for a good idea and sorry if this was more than you wanted to hear on the subject. :) Polly @ Helping Little Hands

Very cool.

Thanks for joining Get Your Craft on Thursday. Please join me next week for another wonderful party!!

Please stop by next week I am having guest over each day and I would love for you to tell them HI!

Science and art wrapped up in one project. They turned out great!
