Expandable and contractible garden hose

A method of transporting water through a garden hose comprising:

• forming an expanding hose, said expanding hose including a non-elastic, bendable elongated outer tube having a first end and a second end, an interior of said outer tube being substantially hollow, said expanding hose including an expandable, elastic elongated inner tube having a first end and a second end, an interior of said inner tube being substantially hollow, said elastic inner tube positioned within said substantially hollow outer tube;
• securing a first coupler to said first end of said inner and said outer tubes;
• securing a second coupler to said second end of said inner and said outer tubes, said inner and said outer tubes being secured to each other only at said first and said second ends and unsecured to each other between said first and said second ends;
• connecting said first coupler to a source of pressurized water;
• connecting said second coupler to a water flow restrictor;
• introducing a flow of pressurized water into said expanding hose through said first coupler;
• restricting said flow of pressurized water exiting the expanding hose, resulting in an increase in water pressure within said expanding hose between said first and second couplers causing said inner tube to expand longitudinally along a length of said inner tube and laterally across a width of said inner tube thereby increasing a length and width of said hose to an extended condition;
• and
• automatically contracting said expanding hose to a decreased length and width by removing said flow of pressurized water into said expanding hose and removing the increase in water pressure within said expanding hose between said first coupler and said second coupler,
• whereby said inner tube moves freely with respect to said outer tube when there is no water pressure differential between said first coupler and said second coupler.
