Why do onions and chips keep washing up on England's south coast? Here's the science

Over Christmas, vegetables, bananas and insulation foam washed up on beaches along England's southeast coast. They were from 16 containers spilled by the cargo ship Baltic Klipper in rough seas. In the new year, a further 24 containers fell from two vessels during Storm Goretti, with chips and onions among the goods appearing on the Sussex shoreline.
