Return of the Party Ball?

Remember the Coors Party Ball? For you greenhorns out there, it was a plastic ball in a box full of about five gallons of beer. It was very popular for awhile, but it had its limitations.One was it took up an inordinate amount of room in the cold box and in consumers' fridges. Second, it went flat within a day or so of tapping. Third, the pricing was bad for all three tiers-everybody except the consumer.Leave it to the Germans
