But (other than too much priming sugar as in the example above) why does it happen, and what can be done about it? Answers can be found in a 2014 paper in the Journal […]

Further on the physics of froth
Hard and soft on the heels of the announcement about beer foam’s anti-spillage property comes other news about beer foam research: “Physics of Beer Tapping,” Javier Rodríguez-Rodríguez, Almudena Casado-Chacón, and Daniel Fuster, Physical Review Letters, 113, 214501, 20 November 2014. The authors report: “The popular bar prank known in colloquial English as beer tapping consists in […]
The effect of beer foam on resisting beer spills
Beer foam, as a subject of experimental inquiry, will be on tap at a physics meeting next week: Abstract: H16.00009: “Damping of liquid sloshing by foams: from everyday observations to liquid transport“ 67th Annual Meeting of the APS Division of Fluid Dynamics, Sunday–Tuesday, November 23–25, 2014; San Francisco, California, Session H16: Free-Surface Flows V: General, […]
More about foam-in-the-pants
Investigator Heidi Toms read about the medical report about the hazard of having one’s pants filled with foam. Toms cautions us that foam in the pants can sometimes, at least in theory, be a good thing, provided there is not a dangerous oversufficiency of foam. She alerts us to the foam-in-pants usage described in US […]
