Abstract
A combination humidifier and moving indoor sculpture is provided comprising a reservoir containing a body of water, an upright helix rotatable about its longitudinal axis, and means for pumping water to the top of the helix. The helix floats on the surface of the body of water, and the water pumped to the top of the helix flows down the helix under the influence of gravity adding humidity to the surrounding atmosphere and rotatably driving the helix due to the change of momentum of the water flowing down the helix.
