Who knew? Apparently some cheese is flammable:
Some 27 metric tons of flaming brown cheese (brunost), a Norwegian delicacy, blocked off a three-km (1.9 mile) tunnel near the northern coastal town of Narvik when it caught fire last Thursday. The fire was finally put out on Monday.
The hefty fat content somewhere around 30 percent is to blame. Kjell Bjoern Vinje, who’s spent fifteen years at the Norwegian Public Roads Administration, reports that this is the first time he can recall a cheese fire on the nation’s roads.
