Hollow bodies which are closed on one side and which are cylindrical are sorted by a sorting device. The hollow bodies have an end-side opening, a base surface situated opposite the opening and a shell surface extending between the base surface and the opening. The sorting device includes first nozzles arranged on an upper guide for conducting a first fluid flow in the direction of a lateral guide, and second nozzles arranged on a lower guide for conducting a second fluid flow in the direction of an outlet. Since the force of the fluid flow is several times greater if the fluid flow strikes a part of the shell surface of the hollow body through the end-side opening of the hollow body than if the fluid flow strikes the base surface of the hollow body from the outside, sorting of the hollow bodies is made possible.
