Sinking Bubbles
A 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!!!
