Making Ice Cream
Changes of State In a journal we read about how to make liquid cream into ice cream without a freezer. We put the cream, sugar and vanilla essence into a small jar. Then we put ice into the bottom of a large jar. Our small cream jar sat on the ice and was then surrounded by ice and topped with rock salt. Everyone had a turn at rolling the jars for four minutes, resting it for one minute and then repeating. We did this over half an hour then opened out jars and discovered we had made ice cream. It was delicious. We ate it in minutes.
