Salt Crystal Experiment 27.10.16

Yesterday He Puna PÅ«manawa made salt crystals.  We had a leader and a resource person to get all the ingredients. You need an adult to boil the kettle/jug and the adult to pour it into the container.  Then pour 1 dessert spoon of salt into the jug and wait until it dissolves . Then get 1 Ice block stick and 1 clear glass jar and a piece of wool. Then tie the wool to the ice block stick then put the stick onto the jar then put the jug of dissolved water into the jar and wait until the crystals grow. I wonder how long it will take?
