A beer widget is the plastic device added to the can that contains pressurized nitrogen gas; when the can is opened, the nitrogen escapes and dissolves into the beer and produces a finer, smaller-bubbled carbonation and head that is thick and creamy.

The original widget was patented in Ireland by Guinness. The "floating widget" is found in cans of beer as a hollow plastic sphere, 3 cm in diameter (similar in appearance to a small table tennis ball) with a small hole in one side. The "rocket widget" is found in bottles, 7 cm in length with the small hole at the bottom.
