St. Patrick’s Day is a holiday that many people look forward to, especially those who love everything green, sparkly and all things Irish. And what better way to celebrate St. Patrick’s Day than with science experiments for St. Patrick’s Day? Today, we show you how to complete a St Patrick’s Day chemistry experiment by making crystal shamrocks!
This activity is not only a great way to get kids excited about science but it also provides a fantastic opportunity to get creative and make something beautiful.
The crystals you’ll create will be unique and eye-catching, and they’ll make for an excellent decoration to display during the St. Patrick’s Day festivities.
So, get ready to put on your lucky lab coat and let’s dive into the world of crystal formation! We’ll be using Borax, water, and other materials.
St Patrick’s Day Chemistry: Crystal Shamrocks
The Crystal Shamrocks chemistry experiment is an excellent way to get your hands on science while also indulging in the St. Patrick’s Day spirit.
This activity provides an opportunity to learn about crystal formation, a fascinating topic in the field of chemistry.
The process of growing crystals involves a straightforward series of steps that require precision and patience.
Through this activity, you’ll be able to witness firsthand how the right combination of ingredients and conditions can lead to the creation of beautiful, sparkly crystals.
It’s a simple process, but the results are impressive and rewarding. You’ll learn how to create a supersaturated solution and watch as the molecules come together to form gorgeous, sparkly crystals.

How to Easily Create Crystal Shamrocks
Making a crystal shamrock as part of St. Patrick’s Day chemistry activity is a simple and super fun project that kids of all ages will love. By following the directions listed below, you can learn just how to show kids how to make these sparkly crystals.
But first, I want to answer a few common questions about borax crystals.
One of the primary benefits of making St. Patrick’s Day chemistry shamrocks is that it provides an opportunity to learn about crystal formation, molecular bonds, and more!
How do crystals form with borax?
Borax, like other minerals and substances, becomes less soluble as water temperature drops.
As a result, when the Borax and water combination is cooled, the water contains less of the Borax and it falls out of the solution.
This causes crystals to develop along the ridges of the pipe cleaners, forming your crystal shamrocks.
Through this activity, participants can observe the process of creating supersaturated solutions and witness how molecules come together to form crystals.
How long do borax crystals last?
Borax crystals last a long time, but after a few weeks, they will start to whiten and crumble back into powder as they lose more moisture.
How do the borax crystals compare with the rock salt crystals in size and structure?
Borax crystals create smaller, less square crystals when compared with rock salt crystals. You can see how salt crystals are different in our post about salt crystal pots of gold for St. Patrick’s Day.
Check them out in our post on how to make crystals without borax.
What Do You Need to Make Borax Crystals?
I like purchasing materials in bulk from because it is much cheaper. Here are where you can find my favorite bulk resources for these borax crystal shamrocks.
- Borax Detergent Booster
- Chenille stems, 1 for each crystal
- Wide mouth jar or glass
- Thread or thin string
- Popsicle sticks

The Science Behind Borax Crystals
What is the science of borax crystals?
When the is water heated, the borax particles dissolve. As the water cools, it cannot hold on to as many borax particles.
Because the borax particles have to go someplace, if a pipe cleaner is suspended in the borax solution, the borax molecules adhere to the pipe cleaner and form crystals.
When you remove the shamrocks from the water and let them dry, you have beautiful crystal shamrocks!
