Then we made the borax solution (I bought borax from Amazon). First we added boiling water to a pot and added 3 tablespoons of borax per each cup of water. Then we added blue food colouring.
We hung the pipe cleaner snowflake into the jar with the pencil resting on top of the jar making sure it was completely submerged. Then we left it overnight and the next day we had a lovely snowflake!
