I’m so excited to share this super simple tutorial on how to make borax crystal hearts. They make for lovely decorations and if you have kids, this craft has a kind of transformative “Wow!” factor. When you buy borax for home use it comes in a powder form, but through the magic of chemistry, it will form crystals if you dissolve it in boiling water and let it cool for a few hours .
Borax is a compound boron mineral that I have been a fan of for many years. I use it to make my own laundry detergent or as a laundry booster for commercially-made laundry detergent, but this is the first time that I’ve used borax to make crystal shapes of any kind. I’m smitten! I hung the finished hearts on a branch we had laying around in the back yard and I’m in love.
Borax Crystal Hearts Craft
• Borax (you can find borax at most stores in the laundry aisle or buy it online)
• Empty glass jars. You can use mason jars or glass jars from your recycling.
• Pipe cleaners
• Twine or yarn
• Wooden skewers (popsicle sticks would work as well)
• Boiling water
- While you are boiling water, shape your pipe cleaners into the hearts.
- Place about 1/2 cup of borax powder in each of your glass jars. When your water reaches a boil, fill your jars almost to the top and stir to dissolve the borax.
- Use twine or yarn to hang the pipe cleaner hearts from wooden skewers in the water as pictured above. I put two hearts in each jar, but made sure the hearts weren’t touching each other so they wouldn’t get stuck together. Let everything sit overnight.
- When you wake up, lovely crystals will have formed over the hearts. Remove the hearts from the solution and from the twine and skewers. Let them dry on paper towels.
- Once they are dry you can use them to decorate whatever you like.
