Just below is the section of my first editing on Wikipedia and is what I found looking at it once again. But it really wasn't written clearly so I did a little more. I've never heard of a beer sucking in any way other than taste. Yet it was written that the Guinness sucks bubbles down. Pushes the bubbles down makes a lot more sense. Perhaps mentioning entrainment was going to far, but it's not wrong. I hope whoever re-edited my changes sees this. Do what you think is best, and feel free to delete these comments.įirst change: The effect is attributed to drag bubbles which touch the walls of a glass are slowed in their upwards travel. This creates a current, which causes the bubbles near the edge of the glass to be sucked downwards by the base of the column, and pushed downwards by the column's head. 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.įinal version: The effect is attributed to drag bubbles which touch the walls of a glass are slowed in their upwards travel. #Houston gay bars with guiness free#īubbles 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. #Houston gay bars with guiness license#.
