Crystal Egg Geodes - Martha Stewart Easter. Geodes can be grown without using egg dye.
The resulting crystals are clear to milky white, like quartz. While large chicken eggshells are suggested in this process, larger eggshells can be used. Simply increase the size of the plastic or glass container and double or triple the amounts of dye (1 packet), alum (3/4 part), and water (2 parts) used to create the growing solution. This Easter craft from Jim "Figgy" Noonan doubles as a science project, offering an opportunity to show kids the crystallization process at work. Lackadaisy Construction.
