Helen likes learning new things all the time and Daddy's friend Peter shows her that you don't always need a laboratory to learn. All you have to do is observe the things around you and watch how they change and transform. By observing and deducing, Helen learns what happens to water when freeze it, what happens to ice when heat it and where the juice we drink comes from.
