A method of conducting a promotional contest by providing a portal that establishes a field for detecting the presence of a field-disturbing element, providing packages respectively having and lacking a concealed field-disturbing element, and distributing the packages randomly to different individuals who carry the packages past the portal so that a package with a field-disturbing element causes the portal to produce a signal indicating a winner of the contest. A can for beverages or the like having a field-disturbing element concealed thereon, for use in such a promotional contest. The element may be mounted in a peelable foil closure member covering an aperture in the can lid.
