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 30 millimetres in diameter with two small holes and a seam. The "rocket widget" is found in bottles, 70 millimetres in length with the small hole at the bottom.
