You need this:
- 1 beer mug made of glass
- Golden yellow fruit gums (eg "Kraftpakete" or "Honigbären" via "DER" Gummibärchenladen)
- Small marshmallows in white
- possibly a ribbon in blue and white checkered
It's that easy:
1. Fill the beer mug with yellow fruit gum until just below the edge.
2. Fill the beer foam from the small marshmallows.
3. Possibly loop the pitcher.
