Ingredients
- Eggshells: Clean shells to hold the salt solution.
- Epsom salt: For dissolving in hot water to create the crystal-forming mixture.
- Water: Hot water for mixing.
- Food coloring: A few drops to tint the solution.
- Small containers for mixing: To prepare the Epsom salt and water mixture.
Instructions
- Rinse the eggshells carefully. Remove any remaining egg and gently clean the shells. Avoid squeezing or scrubbing too firmly; eggshells can split or crumble.
- Let the shells dry completely. Set the rinsed shells aside until they are dry.
- Dissolve the Epsom salt. In a small mixing container, combine Epsom salt with hot water. Stir until the salt has dissolved.
- Tint the solution. Add a few drops of food coloring and stir to distribute the color.
- Pour the mixture into the shells. Carefully fill each eggshell with the colored solution. Move slowly to avoid spilling or cracking the shell.
- Leave the shells to sit. Place the filled eggshells somewhere they can remain undisturbed for a few days.
- Check the geodes gently. After a few days, look for crystals forming inside the shells.
Notes
Handle the shells gently from the start to avoid cracks, and keep them stable during the waiting period. Expect some variation in results.
