How to Make ice cream and explore the ingredient salt
In this Education video tutorial you will learn how to make ice cream and explore the ingredient salt. Ingredients are a cup of milk, sugar, vanilla, some salt, ice and two plastic bags. Add two tablespoons of sugar to one cup of milk, a quarter teaspoon of vanilla, stir it up and pour it in to a plastic bag. Put this bag in another bigger plastic bag, add some ice and about half a cup of salt. Seal the bag and start mashing it. After about 10 minutes, it will turn into ice cream. When salt is added to ice, it drops the melting point of ice. This temperature drop caused the milk to freeze making the ice cream.
