Thousands of rubber ducks who've been drifting at sea for more than a decade are scheduled to make landfall on the UK some time this year. The long-trekking tub toys started their journey in the Pacific when the container they were stored in broke free in a storm and released them. Ocean currents then swirled them north, where pack ice gradually pushed them through their very own northwest passage. Some of the outliers have already made landfall on various North American coasts, but the bulk are predicted to arrive in South West England some time later this summer. Surprisingly, this plasticized voyage has provided a great deal of valuable information on ocean currents.
