Crystal growing is a fantastic Science activity that you can do at home with the kids. Watch the kids be amazed at the crystals they grow.

What you’ll need:

  • powdered borax
  • pipe cleaners
  • sewing thread
  • food colouring
  • skewer
  • heat proof container
  • measuring spoon
  • water


  1. Use 2-3 pipe cleaners to form a shape.
  2. Tie a piece of thread to the pipe cleaners, long enough for the pipe cleaners to be submerged but not touch the sides or bottom off your container.
  3. Place 3 cups of boiling water in your container, stir in 9 tablespoons of borax and a few drops of food colouring.
  4. Hang your pipe cleaners on the thread from your skewer so that it is fully submerged.
  5. Cover the top of your container in a tea towel or foil and leave overnight.
  6. Using your skewer, pull up your pipe cleaner and discover the magical crystal you have grown.

My kids love Science experiments and I am always on the look out for easy ones we can do at home.

  • Now this is a super cool thing for the school holidays.


  • I love doing these quirky home science experiments. They usually work and are usually so interesting


  • Looks complicated, but worth a try.


  • lol my daughter and i tried to make this before but ours never worked. We never had to use borax though. I might give it a try again because i remember doing this experiment as a child and it was cool.


  • Looks great. No I have never grown my own crystals.


  • Seriously? This is great. My son is really into crystals and rocks so I can imagine is excitement at making his own.


  • Wow what a fun idea.


  • Wish I’d known how to do this when I was at school.


  • My daughter would love to do this, and in several colours. But where you do you buy borax from?


  • Cool !! I’m sure my kids would be intrigued !


  • Love doing this as a child and had forgotten about how it was done.


  • It is beautiful!


  • Please be aware that borax is very toxic. If oyu let the children help you, make sure they are wearing gloves and don’t touch it with bare skin at all.
    Having said that it is really pretty.


  • I love the blue shade you got.


  • Growing your own crystals would be alot of fun!
