- Borax
- Hot water
- Jar (that can hold the solution)
- Blue food coloring
- String
- Pencil

How to Make Crystal Starfish Geodes
Follow these step-by-step instructions for a successful crafting experience.
Step 1: Shape Your Starfish
Begin by taking the pipe cleaners and bending them into the shape of small starfish. Aim for five arms, each evenly spaced to create the classic starfish silhouette. The more intricate your shapes, the more impressive the final crystals will look!
Step 2: Prepare the Borax Solution
In a jar, mix several tablespoons of borax into hot water until it dissolves completely. Add a few drops of blue food coloring for a lovely hue. The amount of blue coloring can vary experiment a little to achieve your desired shade.

Step 3: Suspend the Starfish
Carefully suspend the shaped starfish in the borax solution using string. Make sure they don’t touch the sides or bottom of the jar, as this can impact the crystal formation. You can tie the string to a pencil that rests across the top of the jar, holding your creations in place.
Step 4: Wait and Enjoy
Let the starfish sit in the solution overnight. As they soak, watch as the crystals start to form. The next morning, gently remove the starfish from the solution and let them dry on a paper towel. You’ll be delighted by the lovely crystal formations that have developed!
Tips for Success
- Use warm water: High temperatures help dissolve the borax more effectively, leading to better crystallization.
- Customize colors: While this project uses blue, try different colors to create vibrant variations of starfish.
- Adjust the design: Consider making different shapes or sizes of starfish for a more diverse display.
Common Mistakes to Avoid
- Not using enough borax: Ensure you add sufficient borax to the water so that crystals can form adequately.
- Starfish touching the jar side: This can cause uneven crystal formation. Double-check their positioning before leaving them overnight.
Ways to Customize It
Get creative! You can experiment with various themes. For instance, try adding glitter to the borax solution for an extra sparkle, or make a whole under-the-sea display by crafting additional sea creatures.
