Abstract: A volatile material delivery device may include a hub having one or more vanes coupled to the hub. A porous material may be coupled to the hub. Optionally, the porous material may be coupled directly to the hub and/or may be coupled indirectly to the hub by being coupled to a vane that is coupled to the hub. A volatile material may be in communication with the porous material so that the volatile material may pass through the porous material. Rotation of the hub may result in rotation of the vanes and the porous material. Additionally, rotation of the porous material may cause or increase the release of volatile material, and rotation of the vanes may generate an air current which may move across the porous material so that the volatile material is distributed into the environment in the air current generated by the vanes.
