No, this is not a cloud photo taken through a dirty lens. It shows huge clumps of dry grass falling from the sky last weekend in parts of the U.K. including Devon, Gloucestershire, Mid Wales, and Lancashire. Electrical engineer Chris Grew, 59, outside at the time with his wife and 16-year-old daughter near Devizes, Wiltshire, offers a first-hand account: "It really was quite a peculiar thing to see. We were sitting having lunch in the garden when at first we saw just a few little bits coming down. Soon it was huge great lumps coming down, covering the garden, the cars, and the caravan. It was all over the place." The fall of hay (PHOTOS HERE) was not quite as mysterious as the rain of apples on Coventry in 2011. Apparently the past couple of weeks of mild weather dried up the ground and warmed up the air, giving farmers an opportunity to cut grass for hay. Clumps were then carried upward, possibly by convection, and swept through the air by warm thermals, later falling back down on the surprised residents.
