Bath or Shower?

Remember the story of Archimedes lolling in his bathtub?

To an observer, he'd have seemed to be wasting time.

While ostensibly doing nothing, however, he discovered the principle of displacement, a cornerstone of physics.

Would he have reached the same insight in a quick shower?

From cnn's money magazine - I just like the graphics - and after help little m. study for the mcat, I finally understand the principal of displacement.
