Ingredients
Ingredients for Borax Crystal Eggs
- 1 cup borax A key ingredient for crystal formation
- 3 cups boiling water Water should be boiling for effective crystallization
- 1 egg A clean egg (real or plastic) Use a real egg hollowed out or a plastic egg
- 1 piece string or thread For suspending the egg in the solution
- 1 piece pencil or chopstick To hang the egg in the solution
- Food coloring (optional) To color the crystals
- 1 glass jar A glass jar or container For holding the borax solution
Instructions
Preparation
- Empty your egg: If using a real egg, carefully remove the insides, leaving just the shell. Rinse and let it dry.
- Set up for hanging: Tie the string around the egg securely, leaving a long enough piece to hang it.
Create the Borax Solution
- Boil water: Get 3 cups of water to a rolling boil (with adult supervision for safety).
- Mix in borax: Gradually add 1 cup of borax to the boiling water, stirring continuously until fully dissolved.
- Add color: If you want colored crystals, mix in a few drops of food coloring.
Start the Crystallization Process
- Pour the solution: Carefully pour the borax solution into the glass jar, filling it halfway.
- Hang the egg: Using the pencil or chopstick, suspend the egg in the solution so it’s not touching the bottom.
- Cover & wait: Cover the jar with a paper towel or cloth to keep dust out. Place it somewhere undisturbed for 24 hours.
Reveal Your Crystals
- Check the progress: After a day, gently lift the egg out of the solution to see your crystals.
- Rinse and dry: Rinse the egg to remove excess borax and let it dry completely.
Notes
Try using multiple food colors for a rainbow effect. Use different molds for varied designs and experiment with borax to water ratios for different crystal sizes.
