A fluid transfer article has a first region having an aerosol precursor and for transferring said aerosol precursor to an activation surface of a second region of said article, said activation surface being disposed at an end of said article configured for thermal interaction with a heater of an aerosol-generation apparatus, and the aerosol precursor having a first dynamic viscosity in an unheated state and a lower second dynamic viscosity in a heated state, wherein in the unheated state the aerosol precursor is substantially retained in the fluid transfer article, both at atmospheric pressure and when a pressure below atmospheric pressure is applied; and in the heated state the aerosol precursor is substantially drawn from the activation surface of said article when a pressure below atmospheric pressure is applied. Advantageously, this combination of features provides a fluid transfer article that does not substantially leak excess aerosol precursor when heated by a heating element.
