1. An aerosol-generating article for generating an aerosol, the aerosol-generating article comprising:
a fluid guide configured to allow movement of fluid, the fluid guide having a proximal end, a distal end, and an inner longitudinal region and an outer longitudinal region separated by a barrier, where the inner longitudinal region comprises an inner longitudinal passageway between the distal end and the proximal end, and the outer longitudinal region comprises an outer longitudinal passageway that communicates external fluid through at least one aperture to the distal end of the fluid guide, such that the external fluid can travel along the outer longitudinal passageway to the distal end of the fluid guide;
a tubular element comprising a gel, the gel comprising an active agent, the tubular element having a proximal end and a distal end and being disposed at the distal end of the fluid guide; and
a cavity between the distal end of the fluid guide and the proximal end of the tubular element.
