Balloons in a Tube:
This thought experiment simplifies the system by negating the complex dynamics of how gas bubbles behave in water. Imagine collecting the gas into "packets" that move ALL of the water above them.


Large vs Small Bubbles
A few large bubbles may rise faster than the same volume expressed as many smaller bubbles, but the cross sectional area of many small bubbles is much larger.
