A: Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them. This is just like helium in air; helium is lighter than air, so it rises, pushed to the top by the pressure around it. dick\u0027s sporting winchester va
