		Macro photography of the two-dimensional hydrodynamic flow focusing phenomenon. The sample liquid to be focused is an aqueous solution of the fluorescent dye fluorescein (shown in green). The focusing liquid is an aqueous solution of the fluorescent dye sulforhodamine B (shown in pink). The flow of liquids follows from right to left. The sheath fluid from the two outer channels flows into the central one where it forces the sample fluid to stretch into a thin (20 micrometers) jet. Ihor Panas
