Materials:
- Borax (sodium borate)

- String
- Pencil or stick
- Food coloring (optional)
- Measuring cup
- Spoon for stirring
Full Step-by-Step:
Prepare the Shape
- Make the Heart Shape:
- Take a pipe cleaner and bend it into a heart shape. Twist the ends to secure the shape.
- Attach a string to the top of the heart, which will allow you to suspend it in the solution.
Create the Borax Solution
- Boil Water:
- In a pot or kettle, boil 2 cups of water.
- Mix in Borax:
- Carefully add 6 tablespoons of Borax to the boiling water.
- Stir until the Borax is fully dissolved. (You might see some residue at the bottom; that’s okay!)
- For added color, mix in a few drops of food coloring at this stage.
Assemble the Craft
- Pour Solution into Jar:
- Pour the hot Borax solution into a heat-resistant jar or bowl.
- Suspend the Heart:
- Tie the other end of the string with the heart shape to a pencil or stick to keep it suspended in the solution.
- Place the pencil across the top of the jar so that the heart hangs down in the solution without touching the bottom.
Wait for Crystals to Form
- Let It Set:
- Leave the jar undisturbed in a cool place for at least 6 hours (overnight is best).
- Watch the magic happen as crystals begin to form!
Tips & Variations:
- Try Different Shapes: Use different cookie cutters to make unique shapes from pipe cleaners.
- Colored Crystals: Experiment with different food coloring for vibrant hues.
- Increase Crystal Size: Use more Borax for larger crystals; just ensure it’s fully dissolved.
- Mix It Up: Try adding glitter to the mixture before allowing it to crystallize for added sparkle.
Frequently Asked Questions:
Q1: What can I use instead of Borax?
A: If Borax is unavailable, try using sugar or salt, but results may vary in structure and clarity.
Q2: Can I use plastic containers instead of glass?
A: It’s best to use glass, as it withstands the heat of boiling water; plastic may warp or melt.
Q3: How do I clean the crystals once they form?
A: Gently rinse them under cold water to remove any residue and let them dry on a paper towel.
Q4: Can I leave the crystals in the solution longer?
A: Yes, leaving them longer will produce larger crystals; just ensure they don’t touch the bottom or sides.
Suggestions:
- Use these heart-shaped crystals as part of a romantic gift package or special occasion decoration.
- Pair them with fairy lights in a jar for a charming nightlight.
- Create a crystal bouquet by making multiple crystal hearts in different colors.
