DIY Science Experiment #9 - Borax Crystals!

As the temperatures keep dropping, stay warm inside and learn about the science of crystals with this cool experiment.

Materials: Borax Laundry Booster, boiling water, medium sized jars or glasses, pencils, pipe cleaners

  1. Create a shape using the pipe cleaners (be creative, it doesn’t have to be a snowflake!)
  2. Using another pipe cleaner, attach the shape that you created to a pencil. It should dangle from the center of the pencil when held horizontally.
  3. Boil the water and pour it into the jars.
  4. Add about 4-5 tablespoons of Borax per jar and stir until dissolved.
  5. Place the pipe cleaner shape into the glass, making sure that it does not touch either side of the glass. The pencil will rest at the top of the glass. Leave it overnight and the crystal will form!

How does it work? Borax is a crystal. When heated, the molecules move farther apart. This makes a lot of room for borax crystals to form. As the water evaporates, the crystals deposit on the pipe cleaner.
