1. A hose, comprising:

  • a) a flexible elongated body having a first end, a second end, and an interior channel defined along its length for transporting a pressurized fluid material between the first end and the second end upon introduction of the pressurized fluid material into the first end;

    b) a biasing means interconnected with said flexible elongated body for generating a first force tending to retract said flexible elongated body longitudinally along its length;

    c) a means for inputting pressurized fluid material into the first end of the flexible elongated body; and

    d) a means for restricting the flow of the pressurized fluid material flowing through said interior channel, wherein restricting the flow results in higher pressure of the pressurized fluid material flowing through said interior channel, wherein the higher pressure of the pressurized fluid material flowing through said interior channel generates a second force tending to extend said flexible elongated body longitudinally along its length, and wherein when said second force is sufficient to overcome said first force the flexible elongated body extends.
