Growing Crystal Flowers

We have been in full Spring mode in homeschool the last couple of weeks. A lot of our learning focus has been on flowers, new growth, baby animals and more. One of the fun science projects that we did was growing crystal flowers! 

We got to craft our pipe cleaner flowers, mix up our batches to leave for 24 hours and then do some observing and predicting about the outcomes ahead!

Growing Crystal Flowers

This experiment is crafty, creative, interesting and pretty straight forward! I liked that all three of my girls could be involved despite their varying ages. 

The pop of colors and floral touch to this experiment tied in well with the curriculum of Spring! 

Also, if your kiddos enjoy collecting and observing crystals, rocks, and gems….this activity it perfection! I know we have rocks and crystals in every corner of our home. 

What You Will Need:

  • Pipe cleaners – at least 8, more if you’d like to create a bouquet!
  • 4 cups, vases or jars of some sort
  • Borax
  • String
  • 4 pencils or popsicle sticks
  • 1 cup + 1 tablespoon for measuring


Step One

Spend time coming up with a hypothesis! Ask questions like..

  • What will happen in each temperature of water?
  • Will the crystal grow or not?
  • How long will it take for crystals to form on the pipe cleaner?
  • What will the flower look like?
  • Why does this reaction happen?

Step Two

Shape your pipe cleaners into flowers!

Step Three

Add 3 tablespoons of borax to each container. Label the containers (COLD, WARM, HOT & BOILING)

1 cup of water, in its appropriate degrees, will go into the containers.

Step Four

Tie flowers to a string and connect to a pencil or popsicle stick. Leave enough slack of string so that the entire flower will be submerged in liquid. (stem does not need to be submerged)

Add liquid into cups.

Submerge flowers.

Step Five

Allow 24 hours for the crystals to form. You can observe and take observations throughout that time!

Step Six

After you carefully remove the crystals and allow to dry. Discuss and observe the outcome!

You can finish out the experiment asking questions like…

  • Did it work like you thought it would?
  • Are all of the flowers the same even though they were in different temperature water?
  • Why do you think each could have been different?
  • Draw a picture of your favorite crystal formation!
