Butter Churn

The butter churn is a device used to convert cream into butter. This is done through a mechanical process, frequently via a pole inserted through the lid of the churn, or via a crank used to turn a rotating device inside the churn. The agitation of the cream, caused by the mechanical motion of the device, disrupts the milk fat.
