It is shown that the total frictional (drag) force acting on a slowly moving absorbing grain in a stationary weakly ionized high pressure plasma can be directed along its motion, causing the grain acceleration. At some velocity the forces associated with different plasma components balance each other, allowing free undamped superfluid motion of the grain.
