How to make a crystal christmas tree

This week over in the free STEM ideas group on Facebook I showed you how to make a….

DIY Crystal Christmas Tree!

  • Sugar/ salt/ Epsom Salts
  • Beakers & Spoons
  • Cardboard Christmas Trees
  • Shallow Plates
  • Food colouring (optional)
  1. Boil a kettle
  2. Pour 50 – 75ml water into your beaker (carefully! It’s hot!)
  3. Stir in as much of your solute (sugar, salt, epsom salts) as you can! You want to create a SATURATED solution i.e. not everything is dissolved!
  4. Pop your cardboard tree onto your plate
  5. Now carefully pour your solution over your cardboard tree and leave it in a warm and sunny spot
  6. Check back regularly to see if your Crystals have grown 🙂
  7. Once they have, remove your tree from the solution, leave it to dry and assemble!
