Abstract: A hollow, substantially conical container has an open end and a closed end. This container is perforated in order to allow liquid to freely pass through it. Attached to the closed end of the container, and coaxial with the container itself, is an inflexible, elongated portion. This portion forms a point at the distal end in order to facilitate ground penetration. A substantially flexible, planar, elongated element has a first end and a second end, and includes an attachment device for firmly connecting the ends, thereby forming a cincture. At least one conical container is connected to the elongated element.
