why is there a ball in my guinness
Widget (beer) A widget is a device placed in a container of beer to manage the characteristics of the beer's head. The original widget was patented in Ireland by Guinness. The "floating widget" is found in cans of beer as a hollow plastic sphere, approximately 3 cm in diameter (similar in appearance to a table tennis ball, but smaller) with at least one small hole and a seam. The "rocket widget" is found in bottles, 7 cm in length with the small hole at the bottom.[1]
Moscow mule The Moscow mule is almost always served in a copper mug. The popularity of this drinking vessel is attributable to Martin, who went around the country to sell Smirnoff vodka and popularize the Moscow mule. Martin asked bartenders to pose with a specialty copper mug and a bottle of Smirnoff vodka, and photographed a Polaroid picture of them. He took two photos, leaving one with the bartender for display. The other photo would be put into a collection and used as proof to the next bar Martin visited of the popularity of the Moscow mule.[3] The copper mug remains, to this day, a popular serving vessel for the Moscow mule.
