The Alster river originates in Henstedt-Ulzburg, north of Hamburg, and shapes the cityscape of Hamburg. "Alsterwasser" (Alster-water) is a popular beer-based drink. Your task is to collect real water from the Alster.
Take a photo of yourself scooping water from the Alster. The Alster must be visible in the background of the photo. The Binnenalster, which is the part of the Alster closest to the city center, also counts.
