Geodes are small rock cavities lined with crystals or minerals. They form through a process in which particles (solute) are suspended in fluid (solvent) and then accumulate. Have some fun creating your own Geodes with some basic house supplies! How many days does it take your crystals to grow?
- Epson salt
- Egg dye (optional)
1. Wash and dry some eggshells. The bigger the shell pieces the better.
2. Dye shells. You can dye just the outside or the inside and outside to create different looks. (optional) Place the shells inside an empty egg carton or small bowl.
