Abstract: The present invention includes a unique magnetic coupling that can be used as a drink identification system as well as a myriad of other useful purposes. In one embodiment, two magnets are connected by a connector. Each of the magnets have at least one surface with an opposite polarity from the other magnet to induce a magnetic attraction. When the magnets are close in proximity, they come together due to the polarity, and effectively produce a loop. The magnets can be attached to the rim of a cup. Decorative charms attached to a small ring or loop can be put onto the connector. Alternatively, the decorative charm can have a magnet attached to it. The charm can then be magnetically attached to the outer magnet of the coupling. A monogram or name tag can be substituted in lieu of a decorative charm. The magnetic coupling can be used for other purposes, such as securing objects in a drink (a decorative umbrella or drinking straw).
