🧂 Ingredients
- 3 tablespoons borax powder
- 1 cup boiling water
- A clean glass jar or heatproof container
- Pipe cleaners
- String
- Pencil or stick
🧰 Tools You’ll Need
- A spoon for stirring
- Kettle or saucepan (for boiling water)
- Scissors (to trim pipe cleaners and string)
- Paper towels or drying rack
🧪 Optional Additions & Substitutions

📋 How to Make Borax Crystals – Step by Step
1. Shape Your Design
Twist and shape your pipe cleaners into fun designs—stars, hearts, initials, snowflakes… anything you love! Kids will especially enjoy creating their own signature look.
2. Set Up the Hanger
Tie a string to your pipe cleaner shape. Secure the other end to a pencil or stick so that the shape hangs freely when the pencil rests across the jar’s mouth.
3. Make the Solution
Carefully bring 1 cup of water to a boil. Add 3 tablespoons of borax powder and stir until completely dissolved. This is your supersaturated solution—aka the magic behind the crystals.
4. Grow the Crystals
Pour the hot borax solution into your jar. Lower the pipe cleaner design into the solution, ensuring it doesn’t touch the jar’s sides or bottom.
5. Wait Patiently
Set the jar somewhere it won’t be disturbed. After about 24 hours, you’ll see crystals forming!
6. Reveal the Sparkle
Gently lift out your design and let it dry completely on a paper towel or rack. Ta-da! Your very own shimmering crystal creation!
🍽️ What to Pair This With
Okay, not edible (please don’t eat it!), but this craft goes great with:
- A rainy day
- A cup of cocoa
- A mini science lesson
- Holiday decorating sessions (hello, DIY ornaments!)
💡 Tips for Crystal Success
- Use a clean jar to avoid contamination.
- Don’t move the jar during the crystal-growing phase.
- Want larger crystals? Let it sit for up to 48 hours!

🧊 How to Store Your Crystals
Store in a dry place. You can hang them as decorations, display them on a shelf, or keep them in a labeled keepsake box. Avoid moisture—humidity can dissolve or dull the crystals over time.
🔍 General Info
Borax safety note: Borax is generally safe to use under supervision but should not be ingested or handled excessively by young children without adult oversight. Always wash hands after handling!
❓ FAQ
Q: Can I reuse the solution?
A: Not really. After the first use, the solution isn’t saturated enough to form more crystals.
Q: Can I use sugar or salt instead of borax?
A: They can make crystals, but the process is slower and the result less dramatic.
Q: How long do the crystals last?
A: Indefinitely, as long as they’re kept dry!
