Thanks to some delightful observations by Bill Beaty on another list
I have been considering the implications of an air bubble rising through
a long water column.
If it were 34 feet high, we would expect the diameter of such a bubble to
increase by 59%
If this is the case, would you expect such a bubble to
1) Maintain constant speed?
2) Accelerate towards the surface?
3) Slow down towards the surface?
