A suction, or vacuum, is created by the coupling of two sections of tubing of dissimilar size. The larger section of tubing has an open ended reservoir attached to one end thereof. The smaller section of tubing has an end plate attached at a point approximately one third of its length. The longer portion of the smaller section of tubing is inserted into the larger tube until the end plate mated to the reservoir. A fluid medium such as water or air is pumped into the reservoir under high pressure filling the reservoir and encompassing the inner section of tubing. The space between the smaller section of tubing and the larger section of tubing is fluidly coupled to the reservoir. The application of the pressurized fluid medium from the reservoir to the space between the sections of tubing creates a low pressure within the inner tubing resulting in a vacuum or suction being effected at the intake of the inner tubing.
