Instructions on how to make borax crystal shapes:

  • Firstly make the shape you want with the pipe cleaner (see notes below)
  • Tie some string to the pipe cleaner shape and at the other end attach the string to a pencil or other rod which is wider than the top of the jar or bowl.
  • Fill the jar or bowl with boiling water
  • Wearing gloves carefully add 1 tablespoon of borax powder and stir until dissolved.
  • Keep adding 1 tablespoon at a time and mixing until dissolved.
  • When no more borax will dissolve and some sits at the bottom then stop adding more.
  • Add a few  drops of  blue food colouring to colour if you wish and mix thoroughly.
  • Slowly drop the snowflake or other shape into the jar ensuring that it is fully immersed and does not touch the bottom.
  • Fix it in position with the pencil resting across the top of the jar.
  • Leave overnight and the crystals will grow on the surface of the pipe cleaners.
  • Hang the shapes using thread.


For every cupful of water you will require approximately 3 tablespoons of Borax.

To make the snowflake take three equal lengths of pipe cleaners. Twist them together at the centre to form a six sided shape.

For more complicated shapes you can use templates like cookie cutters and simply bend the pipecleaners around the shape.

Borax crystals cannot be coloured although blue dye will add a blue hue to them.

Using coloured pipe cleaners will produce coloured shapes.
