So I was reading an article late one night, and the writer tried tosound smart and mentioned how water "retains a memory" and if yousplashed a few drops of water on your hand, the water would follow thesame path, like how if you throw water on a window, the water willalways "trace" the same path. He called it the "something" effect, and Ican't remember what it was called, any suitably super smart scientistshere to solve this dilemma of mine?

Dear nitin,

If I were to drip drops of water on the same spot of a slanted peice of glass the water would tend to roll down in similar ways. This is because the first drop(s) will leave a traced out path of shallow water that the other water drops will tend to follow like little roads.
