When the flakes start flying, get set up to make your very own sparkling, indoor snowflakes. Or maybe you live among the palm tress and dream of gently falling snow. Either way our beautiful crystal snowflakes are easy to make! You can enjoy your crystal snowflake ornaments all winter long with our simple borax crystal growing recipe! A classic science activity for homemade kid’s STEM!
CRYSTAL SNOWFLAKE ORNAMENTS!
FUN WINTER SCIENCE EXPERIMENT!
These crystal snowflake and icicle ornaments are a set it up and forget about it kind of science experiment! Explore snowflake design with our updated snowflakes below!
Science is amazing, and this is one of our favorite winter science ideas.
NOTE: If you rather not use borax powder to grow crystals, check out our salt crystal snowflakes. This winter science activity is perfect the youngest scientist!
BORAX CRYSTAL SNOWFLAKE SUPPLIES
Since you are dealing with hot water, my son watched the process while I measured the solution stirred, and poured it. An older child might be able to help a little more! If you need more hands on, choose our salt crystal snowflakes instead.
I have added a few supplies from Amazon. We belong to their affiliate program.
Borax (found with laundry detergent)
Jars or Vases (glass is preferred)
Craft sticks (pencils)
String or Ribbon
MAKE YOUR PIPE CLEANER SNOWFLAKES
You can cut a pipe cleaner into thirds, place them together, twist the center to hold them together and pull the 6 sides to look like a snowflake. Then you need to
cut 6, 1.5” pieces of matching pipe cleaner and twist one onto each arm of the snowflake to make it look more snowflake like.
Tie a long piece of string to the center of the pipe cleaner snowflake and wrap the other end around a pencil.
For the icicles, my son wrapped the pipe cleaner around a marker to make it curl! Whatever shape you make will look great. Check out our crystal gingerbread man we wrapped around a cookie cutter.
Craft your own snowflake designs. Want to learn more about snowflakes, we have put together some great information here.
Hint: Double check the opening of the jar with the size of your shape! It’s easy to push the pipe cleaner in to start but difficult to pull it out once all the crystals have formed! Attach the snowflakes to popsicle sticks and check length of string too.
A good tip is to make sure you have the right string length so that the pipe cleaner is not touching the bottom. Ours touched and although the crystal ornament was fine once gently pulled away, it did stick!
MAKE YOUR CRYSTAL SNOWFLAKE BORAX SOLUTION
The ratio of borax powder to boiling water is 1:1. You want to dissolve one tablespoon of borax powder for each cup of boiling water. This will make a saturated solution which is a great chemistry concept.
Since you need to use boiling hot water, adult supervision and assistance is highly recommended.
Water is made up of molecules. When you boil the water, the molecules move away from one another. When you freeze water, they move closer to one another. Boiling hot water allows for more borax powder to dissolve to create the desired saturated solution.
Once you have filled your jars with the borax solution, hang your snowflakes or icicles down inside the jar. You need to make sure they are fully emerged but not touching bottom or sides of jars.
You want to set the jars in a quiet place where they won’t be disturbed. No tugging on the string, stirring the solution, or moving the jar around! They need to sit still to work their magic.
After a couple of hours, you will see some changes. Later on that night you will see more crystals growing! You want to leave the solution alone for 24 hours.
Make sure to keep checking to see the stage of growth the crystals are in!

The next day, gently lift out your crystal snowflake ornaments and let them dry on paper towels for an hour or so…
CRYSTAL SNOWFLAKES SCIENCE
You read a little bit about saturated solutions and mixtures above when you made the borax solution. Within the liquid there are still large particles that will settle slowly. Those particles land on the pipe cleaners and of course the bottom of the jar.
As the water cools, the water molecules return back to their normal state, and this is when the particles start to settle. If the cooling process is to quick or the jars are disturbed, you may end up with irregular shaped crystals. This is because the impurities were not able to separate.
Let your crystals work their magic overnight. We were all impressed by what we saw when we woke up in the morning! Not to mention, we had some really beautiful ornaments for the tree! Or you can hang them in the window like a sun catcher.
