A herd of dairy cows nearly lifted the roof off their barn in central Germany when methane released by the animals caused an explosion.
Police in Hesse state said in a statement that a static electric charge apparently triggered the detonation, and a spurt of flame, on Monday at a farm in Rasdorf. The roof was slightly damaged and one cow suffered light burns. No people were hurt.
