Snowflakes (Creative Chemistry Experiments)

You will need:

  1. Cotton string
  2. Wide-mouth jar
    or utensil
  3. White pipe cleaner
  4. Borax powder
  5. Pencil

It isn’t just freezing weather in which you would find snowflakes. Make your very own snowflakes at home, overnight. What’s more? Unlike the real ones, these snowflakes won’t melt!

INSTRUCTIONS

  1. Before you begin remember for one rock candy to be made 1 jar, 1 pencil and 1 string are required.
  2. Take a white pipe cleaner and cut it into 3 pieces of equal length.
  3. Twist the 3 pieces in the centre and also make them overlap in the centre so that the structure may resemble a 6-edged star.
  4. Tie one end of the cotton string to a pencil and the other end to the star.
  5. Boil water (preferably ask an adult to do so), and pour the boiling water into a wide-mouth jar.
  6. For every 1 cup of water that you added, dissolve 3 tablespoonfuls of borax powder into the water.
  7. Place the pencil over the mouth of the jar, and let the star go into the jar of boiling water.
  8. Leave it overnight.

RESULT

Next day, wake up to find your very own handmade snowflake! The Borax in the hot water creates a super saturated solution, which once cooled down cannot hold the Borax, resulting in borax crystals ‘coming out’ of the water to cling to the pipe cleaner.
