Ingredients
- Eggshells: Carefully emptied shell halves
- Borax: 3 tablespoons
- Water: 1 cup of boiling water
- Food coloring (optional)
- Container for mixing: A stable container that can hold boiling water
- Stirring stick: For mixing the borax into the hot water
Instructions
- Empty the eggshells carefully by opening them gently to maintain their shape.
- Clean the shells by rinsing them to remove any remaining egg and leave them ready for the solution.
- Prepare the borax solution by measuring 1 cup of boiling water into your mixing container and adding 3 tablespoons of borax, stirring until dissolved.
- Add food coloring to the solution if desired, stirring gradually until you achieve the desired shade.
- Place the eggshells gently into the borax solution, ensuring they fit without being crowded.
- Leave the container undisturbed for several hours or overnight to allow crystal growth.
- Carefully remove the shells from the mixture and set them aside to dry.
Notes
Handle the fragile shells gently and ensure an adult manages the boiling water. Crystals will form over time, so patience is key.
- Prep Time: 10 minutes
