Guinness bubble/widget followup: limerick

A followup to yesterday’s post about “Beer bubble appreciation in Limerick“:

Martin Eiger, the Limerick laureate, points to a Technology Review article about the new Guinness Stout beer bubble study. Tech Review notes that the study authors, who are mathematicians at the University of Limerick, and opens with this headline:

Mathematicians Reinvent The Beer Widget — Paper could replace the plastic widgets that give canned beers a better head, according to a new mathematical analysis”

Eiger has composed a tribute limerick:

The danger upon us was drastic,
But now there’s an answer.  Fantastic!
Take your beer from the fridge.  It
Will still have a widget,
But one made of paper, not plastic.
