We used the directions on suite101.com to make Geode Easter Eggs!
Or eggs are still in the process of forming so I don't have any finished product pictures yet although I will say it may have been more about the process than the results ~ we'll see.
May I suggest that you prep the eggshells BEFORE the project ~ like the night before when the kiddo(s) are fast asleep or you may have to break out the hair dryer to speed along the process. Not that I had to do that or anything.....
We ended up using Epsom Salt, Table Salt, Cream of Tartar and Baking Soda for our experiment.
Madison loved mixing the materials and adding the dye!
Stay tuned to see how the project turns out!
