Each plastic cup has a hole in the bottom which is wide enough for a nozzle to be inserted. The key to keeping the hole sealed when beer is put in through the bottom is via a circle magnet that when pushed up by the nozzle lifts up so beer can be put in. When the beer is full, the machine automatically cuts off and all a bartender needs to do is just pull the beer off of the nozzle and the magnetic circle is then drawn back down to the cup by a tin magnetic ring embedded in the cup.
