Materials
For this project, you’ll need:
- Borax
- Water
- Clear jar or container
- String
- Pencil
- Food coloring (optional)
Keep safety in mind when handling borax and hot water, as these materials can be hazardous. Always ensure adult supervision is present during this part of the project.
Steps
Prepare the solution: Combine 3 cups of boiling water with 1 cup of borax in a jar. Stir until the borax dissolves completely. You will see the water become clear. This clarity shows the borax has fully blended in.
Add color: If you want your sea urchins to have color, add a few drops of food coloring to the solution and stir gently. Observe how the color spreads, creating a uniformly tinted liquid.
Set the structure: Tie one end of the string to the pencil and the other end to the base of the jar, ensuring it hangs inside without touching the bottom. The string will carry the solution, leading to crystal growth.
Wait and watch: Place the jar somewhere it can sit undisturbed for at least 24 hours. During this time, crystals will begin to form. You’ll notice them beginning to settle along the string.
Check for growth: After a day, check the crystals. If they look good, carefully remove the string. Look for vibrant colors and interesting shapes as you lift the string from the solution.
Dry the crystals: Allow the crystals to dry completely on a piece of paper towel or dish for a few hours. This step helps to eliminate any remaining moisture. Once dry, they should feel solid and firm to the touch.

What goes wrong and how to fix it
One common issue is that crystals might not form properly. If the solution is too cool or not saturated enough, crystals can fail to grow. Try reheating the solution, ensuring the borax dissolves completely before cooling.
Another problem is that crystals may be small or misshapen. This can occur if they dry too quickly or were disturbed during growth. To improve this, ensure the jar is in a stable location, free from vibrations and drafts.
Where to display it
Once your colorful rainbow crystal sea urchins are fully formed and dry, they are ready to be displayed. Place them on windowsills where sunlight can enhance their vibrant colors. Another great spot is on shelves, where they can catch the eye of visitors and add a touch of ocean-themed decor.

You can also combine these sea urchins with other decorations. For instance, integrating them with colorful crystal decorations will create an even more lively display.
Variations
Feel free to experiment with different colors and sizes of crystals. You can change the food coloring to create unique hues. Mixing various colors in one jar can yield stunning results that resemble a colorful coral reef.
Another variation is to use different shapes or containers. Instead of jars, try shallow dishes or other interesting glass forms. Each choice will affect how the crystals grow.
FAQs
How long does the process take?
The actual waiting time for crystal growth is about 24 hours. However, the whole project may take up to two days if you include drying time.
Can I use different types of borax?
Yes, as long as it is pure borax and not mixed with other chemicals, you can use various brands. Just ensure that it is suitable for craft projects.
Will kids be able to help with this craft?
Absolutely! Children can assist with adding the borax, stringing the crystals, and, of course, observing the fascinating changes.
What should I do if my crystals are cloudy?
Cloudiness can occur if there is too much borax or dirt in the solution. To achieve clearer crystals, try starting fresh with clean materials and a more precise measurement of borax.
Can I make this craft outside?
While you can do this project outside, ensure it is in a shaded spot. Direct sunlight can heat the solution too much, affecting how the crystals grow.
Why did my crystals not grow as expected?
Improper temperature or movement can hinder crystal formation. Ensure a stable environment where the solution can cool slowly without being disturbed.
