  • Patent number: 5349997
    Abstract: A portable and highly efficient method for filling the hard to reach watering stands of inside trees, and particularly where the environment or nearby objects are susceptable to damage from splashes or spilled water. The invention is made up of approximately four sections of loosely fitting tubing sections with an angular set funnel at the top, which are held together with a tensioned inside elastic cord, and which can be placed downward through the limbs of an inside tree to quickly feed water from the funnel to the watering stand with a syphon effect generated by the moving water in the full length assembled tubing.
