We are learning a lot about ocean currents and the winds because of ducks -- and they aren't even real ducks. A cargo vessel in the Pacific Ocean lost some containers during a storm. One contained 29,000 plastic ducks for children's bathtubs. The ducks stayed afloat. Three years later they are still turning up in strange places all around the globe. Scientists love it. They call it the "quack heard round the world." It's a humbling experience to discover how little we know when compared to how much there is to learn. God may need to ask us, as He asked Job so long ago, "Where were you when I laid the earth's foundation? Have you journeyed to the springs of the sea or walked in the recesses of the deep?" (Job 38:4, 16)
