Today we are going to learn how to make butter.
When you think of a mixture of substances what do you think about? Probably not cream?
Cream is a type of mixture called a colloid, it is made up of very tiny particles of fat dispersed in water.
What you need
- Thick cream
- A container with a lid
- Let the cream warm up to room temperature.
- Half fill the container and shut the lid tightly.
- Shake the jar until you feel a lump form.
Your cream should have turned into a lump of butter with some milky looking liquid left behind.
What do you think of the taste? It should taste quite different to shop bought butter as it doesn’t have any added flavourings or preservatives.
The Science Bit
When you shake the cream the fat particles stick together, which forms butter.
Cream and butter are a type of colloid known as an emulsion. Did you know it was so easy to make butter?
