GROW SNOW

What You Need:
  • String
  • Wide mouth pint jar
  • White pipe cleaners
  • Blue food coloring (optional)
  • Boiling water (with adult help)
  • Borax Laundry Detergent (NOT Boraxo soap)
  • Pencil
How To Make It:
  • Cut a white pipe cleaner into 3 equal sections. Twist the sections together in the center so that you have a "six-sided" star shape. Pipe cleaners and string form a snowflake base for the crystals to grow on. If your points are not even, trim the pipe-cleaner sections to the same length.
  • Attach string along the outer edges to form a snowflake pattern. Attach a piece of string to the top of one of the pipe cleaners and tie the other end to a pencil (this is to hang it from).
  • Fill a widemouth jar with boiling water. Mix borax into the water one tablespoon at a time. Use 3 tablespoons of borax per cup of water. Stir until dissolved, (don't worry if there is powder settling on the bottom of the jar). If you want you can add a little blue food coloring now to give the snowflake a bluish hue.
  • Insert your pipe cleaner snowflake into the jar so that the pencil is resting on the lip of the jar and the snowflake is freely suspended in the borax solution.
  • Wait overnight and by morning the snowflake will be covered with shiny crystals.
