How to Make Epsom Salt Crystal Ornaments

How to Make Epsom Salt Crystal Ornaments
By Nichole Guza-WaltnerJan 28, 2025

Astound your children by turning a pipe cleaner into a delicate crystalline decoration! 

This craft is easy to accomplish with minimal mess. Enjoy it as a simple handicraft project or take it a step further and learn some of the science behind the activity.

This particular tutorial uses a star shape, but of course, you can form the ornament into whatever shape you’d like for any holiday or just everyday crafting! 

  • Make letters and to spell out initials, names, or words.
  • Make leaf or pumpkin shapes from orange pipe cleaners for fall.
  • Make hearts out of red pipe cleaners for Valentine’s Day.

If your shape is large, you may need to create a double batch of epsom salt solution. For multiple children doing this craft, each child will need their own crystal forming solution. Or you could mix up a much larger batch and suspend multiple ornaments into it as long as they aren’t touching each other or the sides of your container. 

Supplies Needed Per Ornament

  • 1 cup water, hot but not boiling
  • 1 cup epsom salt
  • embroidery thread, string, bakers twine, or ribbon
  • scissors
  • 1 pipe cleaner 
  • 1 stick, straw, or pencil
  • jar or other container*

*Make sure your container is wide and deep enough to submerge your pipe cleaner ornament in the epsom salt solution without touching any edges or the bottom of the jar. 

Epsom Salt Crystal Ornament Directions

Read through all the directions and watch the video first so you have the big picture of where this craft is heading. Then go back and follow the steps one by one.


Science Background

To take the activity farther, learn some of the science behind your activity. 
Read pages 66-67 from the Usborne Illustrated Elementary Science Dictionary, part of Science E Package. Discuss solutions, suspensions, and separating mixtures. Ask your children these questions about the activity:


Q. What is our solute? 

A. The epsom salts

Q. What is our solvent?

A. The hot water

Q. Did we create a solution or a suspension

A. Solution

Q. How did we partially separate our mixture?

A. By letting the epsom salts reform as crystals on the pipe cleaner, we removed much (but not all) of it from the liquid solution. 

Q. How could we remove all the epsom salts from the solution?

A. By boiling it or simply allowing it to evaporate naturally.

How to Make an Epsom Salt Crystal Ornament

Look at the seven types of crystal shapes here.

  1. Cubic or Isometric
  2. Orthorhombic 
  3. Monoclinic 
  4. Triclinic 
  5. Trigonal
  6. Hexagonal
  7. Tetragonal

Q1. What shape are our epsom salt crystals?

Q2. What is the chemical name of epsom salts?

A1. Monoclinic—cylindrical rods or spikes

A. Magnesium sulfate (MgSO₄)
