Why does the bubble in the infusion bottle rise not in a straight line but in a curve?

The laws of physics tell us that all objects are the most stable in the position with the lowest potential energy, so all objects will tend to this stable position and will definitely choose the simplest path to reach this position. This is a macro explanation. But as far as bubbles are concerned, each bubble is similar, so it can be considered as the same, and the water level in the bottle will not change much between two bubbles. So the initial state of the foam is the same, and it is reasonable to rise along the same path. It is considered that the paths are the same, because the bubbles are generated in the inverted bottle mouth and then rise vertically under the buoyancy, so the paths look similar.
