A mixing apparatus including a frame, a housing, and a pair of thrust generators are disclosed. The housing is pivotably mounted to the frame and is movable between a retracted position substantially parallel with the frame and an extended position substantially perpendicular to the frame. The thrust generators are opposingly mounted to the housing and face opposite directions both when the housing is in the retracted position and when the housing is in the extended position. Various mixing and disposal methods are also described.
