When visiting the Adriatic coast, where the campsites (and german tourists) do not cease, there is something particularly peculiar: waterballs. In one giant transparent ball is often one child who stumbles over their feet, in the sea but without touching the water. A string keeps them from floating away. Usually there are several children in several balls, running, jumping, falling, sometimes bumping into each other - whilst being surrounded by plastic. Maybe the guardians do not have to guard as much.
