Zusammenfassung:	In order to apply decorative effects to a multilayered coffee surface, particulary a crema, a focused air jet for drawing or writing is contactlessly guided across the surface, wherein the air jet pressure at the action point is selected to overcome the surface tension of the multilayered surface and to produce swirls between the individual layers. To carry out this method, a wand is used as a writing implement, the wand containing a compressed air source and a switching element, and a small airflow tube (9, 15, 21) protruding from the housing (1, 10, 16) of the wand as a drawing- or writing nib. The compressed air source can also be a replaceable capsule (12) filled with a compressed air. It is particularly effective if a blower (19) driven by a battery-powered electric motor (18) is accommodated in the housing (16) of the wand as a compressed air source.
