    Abstract: A container having a captive rotatable magnet to induce spinning of a separate unattached stirring implement placed in the container. The captive rotatable magnet may be part of an active mixer attached to the container. It may also be passively housed in a chamber in the bottom of the container to be spun under the influence of an external mixer to transmit by coupling the spinning to the separate spinning implement. The stirring implement is magnetically retained within the container during the pouring of a mixed substance.
