1. A fire-containment device for shaping a pressurized liquid stream, the device comprising:
(a) a conduit, adapted for intake and transmission of a liquid stream, wherein said conduit includes:
(i) a hose coupling disposed on an intake end of said conduit, said hose coupling adapted for coupling a garden hose or a fire hose to said conduit,
(ii) an outlet opening on an outlet end of said conduit; and
(iii) a half-cylinder pipe defined by a half cylinder-shaped upper sidewall and a planar lower sidewall between said hose coupling and said outlet opening, said half-cylinder pipe having a half-cylinder cross-section and adapted to increase pressure of a liquid entering said conduit via said hose coupling;
(b) a non-planar shaping piece configured to shape said liquid stream into a liquid shield, said liquid shield resulting from said liquid stream impacting on said non-planar shaping piece, wherein said shaping piece is implemented as a half-cone element, the half-cone element having a base on one end and an apex on an opposite end, a curved upper surface and a flat lower surface, the flat lower surface being triangular in shape, the half-cone element being positioned such that the flat surface is on a common plane with the lower sidewall of the half-cylinder pipe and the apex of the half-cone element faces the outlet opening; and
(c) a lateral displacement mechanism adapted to adjust a distance between said conduit and said shaping piece.
