Wacken Open Air Festival, the world’s biggest heavy metal music festival, has come up with an ingenious way to keep its 75,000 visitors hydrated. Rather than delivering beer by truck constantly, they have installed a 7-km long ‘beer pipeline’ that will transport roughly 400,000 liters of beer straight to the tap. Saving not only the festival grounds from being driven on constantly from delivery trucks, the wasted time having to change thousands of kegs, the pipeline will do this job and more. Constructed just a few feet below the ground, the pipeline will not only keep the beer cold but organizers also claim it will allow bar staff to pull as many as six beers per second.
These improvements, along with improved drainage systems, are expected to cost an impressive €1 million. That's commitment, ingenuity and thirst quenching all in one!
