Said paddle is submerged in a liquid content of said vessel, and having a planar curvature that coincides with the drinking vessel wall contour, and moves in an arc linear motion about a fixed pivot when said tab is operated and released by a thumb finger of the same hand holding the drinking vessel. This creates a stirring or mixing action when said sequence of operation is repeated many times
