I cannot figure out your orientation with respect to the trajectory of gravity in this photo. If you're mostly horizontal, that makes the most sense of the bubbles (but not of the pipe); whereas, if you're mostly vertical, that makes the most sense of the pipe (but not of the bubbles).
Also -- and I'm not certain of the way in which we are to quantify bubbles -- but, your bubbles take up a surprising amoung of real estate. I don't know how you'd do that.
I cannot recall the last time that I took a bath, but my masculinity has been getting out of hand lately, so perhaps to take the unruly edges off of it I will take one at your recommendation (wearing a green mankini, perhaps), whilst smoking a pipe. I'll just order a rain cap, first, to keep the bubbles out.
