Annotation: The technique of solid fluid jet formation with small-scale turbulence is considered. This turbulence is generated by fractal square grids in the area of grid turbulence decay and it moves to a jet. Eddies are impossible in such turbulence flow and consequently, occurrence of small-scale turbulence in the jet can impede strong turbulence and restrain jet breaking. A new procedure can increase the action range of the power water-jet guns and can be applied in those technologies where a solid jet is required. No laminarity in the Fontana Jumping Jet has been found and their exceptional jet stability has been explained by presence of a small-scale turbulence in them. This is what upholds the feasibility of the presented conceptual procedure.
