ABSTRACT:
Flowable materials, such as cement and sand, are mixed by placing the materials to be mixed in an elongate flexible resealable bag having handles at its opposite ends and alternately raising and lowering the handles relative to one another to cause the materials to tumble alternately in opposite directions within the bag. The bag is fashioned to have a greater girth at its center than near its ends.
