The tube preferably has a uniform circular cross-section along an entire length thereof. The elongated tube is configured to define a pair of discrete closed ends, an inner periphery, an outer periphery, an upper apex, and a lower apex. The elongated tube further has at least one row of apertures formed between the inner periphery and the upper apex of the tube along the entire length thereof. Next provided is a linear coupling pipe mounted on the tube for coupling with a water source, wherein water is sprayed upwardly and inwardly with respect to the elongated tube.
