Gassy cows blamed for barn blast
A herd of dairy cows nearly lifted the roof off their barn in central Germany when methane released by the animals caused an explosion.
A static electric charge apparently triggered the detonation, and a spurt of flame, on Monday at a farm in Rasdorf, police in Hesse state said.
The roof was slightly damaged and one cow suffered light burns. No people were hurt.
Police said 90 cows are kept in the shed and it was not clear why quantities of methane had built up. Bovine belching and flatulence releases large quantities of the gas.
