Sinking BubblesA long time subject of bar conversations has been the observation that gas bubbles travel
downwards in a pint glass of
Guinness. The effect is attributed to drag; bubbles which touch the walls of a glass are slowed in their upwards travel. Bubbles in the centre of
the glass are, however, free to rise to the surface, and form a rising
column of bubbles. The rising bubbles create a current by the
entrainment of the surrounding fluid. As beer rises in the center, the
beer near the outside of the glass falls. This downward flow pushes the
bubbles near the glass towards the bottom. Although the effect occurs
in any liquid, it is particularly noticeable in any dark nitrogen
stout, as the drink combines dark-coloured liquid and light-coloured
bubbles.
Guinness is, indeed, good for you. Mexican Beer is better!!!
