Large Hadron Collider suffers carb attack
Efforts to get the Large Hadron Collider up and running just encountered a temporary snag, according to yesterday's online edition of The Times of London. A crusty chunk of bread “paralysed a high voltage installation that should have been powering the cooling unit.”
