Cow farts blow roof off barn (almost)

Gas from a herd of 90 dairy cows caused an explosion in Germany, injuring one of the animals.

A herd of dairy cows nearly lifted the roof off their barn in central Germany yesterday when methane released by the animals caused an explosion.

A static electric charge apparently triggered the detonation, and a spurt of flame, at a farm in Rasdorf, police in Hesse state said.
