"Cervejoduto" was made for Wacken Open Air.
An underground system spanning 7 km in length is being built for this year's Wacken Open Air festival. The "beer pipeline," as it's being called, will transport over 400,000 liters of beer during the festival.
The underground pipeline structure is 80 centimeters deep and will have enough pressure to fill six glasses of beer in six seconds.
The average consumption of each fan attending the festival is 5.1 liters of beer during the three days of shows, well above the average of other events.
