Path of least resistance for water?

Question

If water follows the path of least resistance then why when slightly tipping a glass of water it runs down the side of the cup rather than dropping straight to the ground?

niels nielsen · Answer

Because there are other forces at work in this case besides just gravity- namely, surface tension. If you take that into account, then the water clinging to the side of the tipped glass as it runs down it is, in fact, following the path of least resistance.
