Freeze it! - Why is there no warm ice cream? (Experiment) |

When ice cream is made by freezing milk, sugar, and flavoring, an important step is churning, or stirring, the ingredients as they get colder. This is what makes ice cream fluffy and soft, instead of hard and solid like a cube of ice.
To see the difference, leave a small scoop of ice cream in a bowl and allow it to melt. Then, put the liquid ice cream into the freezer and wait an hour or two for it to freeze again.
What do you find when you take the bowl back out of the freezer? Does the re-frozen ice cream still seem fluffy, or is it frozen into a hard block that would be a little less yummy to eat?
