Next, grab some different colored pipe cleaners, string, popsicle sticks and a few mason jars. You’ll want to go on a hunt for small shapes throughout your house. These could be puzzle pieces (like I used), cookie cutters, or small toys. You can even free hand your shapes if you’d like! Just make sure that they fit easily through the mouth of the mason jar.  

Here is the best DIY crystal recipe ever! With Borax, pipe cleaners, and water you can make the coolest crystals in a matter of hours. How fun would this be to do with a class full of preschoolers?! This may look like just a fun activity for kids, but it can also be a STEM science experiment. Doing this activity during the holidays? Turn these amazing borax crystals into Christmas Ornaments.

Step 2. Make the pipe cleaner shapes

Wrap each pipe cleaner around your shape, twist the ends together securely and snip off any extra pipe cleaner length.  Then tie a piece of thin ribbon, string or fishing line to each shape like an ornament. 

My kids loved this fun crystal making activity using pipe cleaners and borax! In less than a day your kids can create their very own homemade crystals. We made our crystals into various shapes, but you can make them any way you like. Think swirls, zig zags, even a puzzle piece. This really is a fun indoor activity to do with your kids.

Does your child like finding cool rocks and do they absolutely love finding pretty gems? Well, they are going to have a blast making their own crystals out of borax and pipe cleaners. Simply create a shape out of pipe cleaners, soak it in a borax solution, and it just a couple of hours you will have a beautiful homemade crystal shape. I love this fun and easy science experiment for kids! What a great way to learn. Share this with a teacher today!

Step 3. Prepare the borax solution

Mix together 2 cups of boiling water and 1/2 cup of borax. This will be enough solution for 2 crystals! Make sure to mix the solution until it is completely dissolved. Sometimes the water cools a bit and the borax doesn’t dissolve completely. If this happens, pop your borax solution into the microwave for 1 minute and then stir to combine. Just be careful because the water will be HOT! 🔥

Do your kids love rocks and gems as much as mine do? Then they are going to flip at how cool this fun and easy DIY crystal making project is! With 3 ingredients, your kids can make the most amazing homemade crystals ever. Make borax crystals in any shape and color imaginable. It only takes 15 minutes to set up and within 5-6 hours the crystals are already formed. How cool is that. You have to try this fun activity with your kids today.

If you’re planning to do more pipe cleaner crystals, double or triple this recipe. For instance:

4 Crystal Shapes: 4 cups boiling water and 1 cup borax

6 Crystal Shapes: 6 cups boiling water and 1 1/2 cups borax

8 Crystal Shapes: 8 cups boiling water and 2 cups borax

Step 4. Pour and wait!

Now that your borax solution is nice and dissolved, pour it into the mason jar to the top of your pipe cleaner shape. The water level should be right at the top of your pipe cleaner. Any higher and borax crystals will form on the string. 

Are you looking for an easy rainy day activity with your kids? Try making homemade crystals! By mixing borax and water you can grow crystals on pipe cleaners.

Let your crystal pipe cleaners sit in the borax solution for a few hours. Ours set for 5-6 hours and formed very pretty prism like crystals! Once crystals have formed on your pipe cleaners, you can remove them from the solution and let them dry on a paper towel. Once dry, these DIY Borax Crystals are pretty strong!

So, the point of all this is to say that you can make your crystals look pretty and delicate or over grown and crazy depending on how long you choose to soak your pipe cleaners in the borax solution.

Helpful Tips

  1. You don’t necessarily have to use a mason jar. A disposable cup would work as long as it is heat proof.
  2. Be sure to wipe up any spills quickly or you’ll have tiny crystals on your counters!
  3. Your shapes should be smaller then the opening of your jar as they will grow as the crystals form. If you make your pipe cleaner shapes too big, you may not be able to get your borax crystals out of the mason jar.
  4. Crystals will form on the bottom of your mason jar. For clean up, simply microwave the borax/water solution in the mason jar for 1 minute or until the borax crystals begin to dissolve. Feel free to use this borax water in your laundry. Borax is a cleaning agent after all!
  5. Adding a few drops of food coloring to your borax solution will make the crystals even more vibrant. Give this a try and let me know how it works!
