The Morning of Green Tea Andante

Random. I was walking back from the office kitchen with a cup of hot water, ready to drop in my green tea at my desk and noticed how the water was rippling on the surface. No matter what I did, I just couldn’t calm the surface unless I stopped and remained motionless. Then I started to wonder, was there some way that I could tap the cup while walking to cancel out the vibrations? Or maybe sing to it.
