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.
