You have two buckets: one is completely filled with water and one is completely filled with milk. Your goal is to fill each bucket with one half water and one half milk. When you are done, each bucket needs to be completely filled -- you cannot lose any of the liquid in this task. What makes this task difficult is this: You are not allowed pour the liquid into any other container. (And before you ask, no you cannot hold any liquid in your mouth and then spit it out.)
