Metal heads are Vernost aka Fidelity (2019)building a 7-km long, underground pipeline to send 400,000 litres of beer to a festival in northern Germany.

No, that's not a line from Jack Black's latest movie, but an actual initiative put in place for Wacken Open Air Festival, the world's biggest metal music festival.

Organisers found out that the 75,000 metal fans who attend the event each year consume an average of 5.1 litres per person over the three day festival, according to statistics portal Statista.

The pipeline, buried 80cm beneath the ground to keep the beer cold, will solve logistics problems of tracks going back and forth, ruining the festival ground.

"In this way, we will no longer have to distribute truck loads of beer kegs across the premises each day," festival spokeswoman Frederike Arns told Deutsche Press Agentur.

The new pipeline will have enough pressure to pour six beers in six seconds.
