A skimmer apparatus has a handle, a net-bottom-rod at a right angle to the handle, offset from the axis of the handle and joined rigidly to an extension of the handle, a movable frame rotatable about an axis at a right angle to the axis of the handle, a slider translatable on the handle, a linkage mechanism joined to the movable frame and to the slider rotating the movable frame about the axis at a right angle to the axis of the handle, and net material joined to the movable frame and to the net-bottom-rod. Moving the slider away from the net employs the linkage mechanism to rotate the movable frame past the net-bottom-rod, such that the net is turned inside out, facilitating divesting material captured in the net.
