Abstract: The subject matter described herein includes apparatus's and methods for storing and mixing materials such as powders and liquids. The mixing apparatus can comprise an impeller portion configured to rotate downward or upward within the main cup, wherein a movement of the impeller portion downward or upward is capable of mixing the contained set of substances, wherein the impeller portion comprises a set of propeller blades, and wherein the impeller portion is connected to a helical shaft portion comprising a first helical strand and a second helical strand wound uniformly in a parallel spiral configuration. The impeller portion facilitates a distributed mixing of the substances and the propeller blades are capable of removing deposits of the substance around the base of a main cup of the apparatus.
