TThe bubbles at the center rise rapidly until they get to the top, just below the head (the "froth"). In doing this, they have pushed and pulled the surrounding liquid with them. At the top, this liquid flowing upwards hits the surface and flows outwards towards the edges of the glass.he bubbles at the center rise rapidly until they get to the top, just below the head (the "froth")
Let's start at the point where you have just poured your pint of Guinness, and it is starting to settle. At the inside surface of the glass, the bubbles are touching the walls of the glass and they experience drag - just in the same way as you can feel if you slide your finger along a glass surface. At the center of the glass, the bubbles are not touching the walls, and are free to go up: this is what bubbles of gas really want to do when they are in a liquid, as we are used to seeing.. In doing this, they h

Since the bubbles have less density than the surrounding water, gravity pulls the water down, and the bubbles go up.

Go to the left side where the barrelfish is behind the rock wall. Use your sub to block the vent that blows bubbles out at you. The bubbles will go inside and shove the barrelfish down. Go down and block the vent there, and the bubbles push him right. Go right and block that vent to shove him to the upper left where you can get your photo.

If you're talking about soap bubbles, they go down simply because the little bit of soap they are made of is heavier than the air. I think its also because when you blow into them, you blow Carbon Dioxide, wich (I am pretty sure) is heavier than the rest of the air.

Does the bubble side of a solar pool cover go up or down if the bubble side is black and the smooth side is blue?
Personally, I disagree with the logic used by those above. If the bubbles are up, there will be larger surface area to absorb the sun's heat. Increased levels of heat absorption seems more important than the rate of heat transfer, especially when considering the fact that heat transfer takes place almost instantaniously.****i have tried it both ways, bubbles up or down. makes little or no difference heating. with bubbles down, though, it is easier to clean debrie off the cover and keep it clean.
