What Makes This Work
When you dissolve Borax in hot water, it creates a saturated solution. The solution can hold a lot of Borax molecules, which will settle and crystallize as the water evaporates. The combination of colorful food dye and the Borax crystals makes for a stunning visual effect. This project not only results in a delightful craft but also demonstrates the fascinating science of crystallization.
Materials
To get started, gather the following materials:
- 6 jumbo craft sticks
- Borax
- 3 cups hot water
- Tall heat-safe jar
- Rainbow food coloring
- Pipe cleaners
- Clear pink and clear blue beads
- String

Steps
- Shape the Pipe Cleaners: Begin by bending pipe cleaners into oversized pencil silhouettes. Ensure they are stylishly oversized; this will make the crystals look even more impressive.
- Prepare the Borax Solution: In a tall heat-safe jar, dissolve Borax in 3 cups of hot water. This step requires adult supervision, as the water is hot. Stir until fully dissolved.
- Color the Solution: Divide the solution into several smaller jars. Tint each with different colors, such as pink, blue, and a vibrant rainbow shade. This adds a fun dimension to your project and makes the crystals even more colorful.
- Suspend the Pencil Shapes: Carefully suspend your pencil shapes in each colored solution. Make sure they are fully submerged. Leave them in the jars overnight. You will notice crystals starting to form on the pipe cleaners throughout this time.
- Remove and Dry: After a day, carefully remove the pencils from the solutions. Lay them out flat to dry. As they dry, they will reveal their beautiful, sparkling crystal transformation, showcasing the colors you chose.
What Goes Wrong and How to Fix It
Sometimes, the crystals might not form properly. If your crystals appear to be rough or uneven, ensure that the solution was saturated enough. If you notice the crystals didn’t adhere to the pipe cleaners, try stirring the solution a bit longer during the dissolution step. It’s all about finding the right balance!
Where to Display It
Once dried, these eye-catching Crystal Rainbow Pencil Geodes can brighten up any space. Consider placing them on window sills to catch sunlight or using them as fun decor on a desk. For a unique touch, display them alongside other vibrant crafts, like a Back-to-School Rainbow Pencil Bouquet.

Variations
Experimenting with different colors and bead arrangements is a fun way to personalize your Crystal Rainbow Pencil Geodes. You could also try different shapes or sizes of the pencil silhouettes. In addition, incorporating other materials, such as glitter, can enhance the sparkle and texture of your crafts even further.

FAQs
How long does it take for the crystals to form?
Typically, you should leave your Crystal Rainbow Pencil Geodes in the solution for about 12 to 24 hours to allow proper crystallization.
Can kids help with this project?
Yes, kids can help shape the pipe cleaners and add food coloring, but adult supervision is necessary when handling hot water and Borax.
What if my crystals look muddy?
If the crystals appear muddy, it may be due to too much food coloring or impurities in the solution. Try using less dye and ensuring your materials are clean.
How can I make my crystals larger?
To achieve larger crystals, use more Borax in the solution and allow the pencils to hang in the solution for a longer period.
What can I do if I don’t have Borax?
If you don’t have Borax, a similar crystallization effect can often be created using sugar or salt, though the appearance will differ.
How long will my Crystal Rainbow Pencil Geodes last?
These colorful creations can last for a long time if kept in a dry area away from moisture, although the appearance may fade over time when exposed to sunlight.
