These Whirling Blossoms are a roundabout calling the passengers to participate actively. The various calices are installed on the rotating platform being each mounted on their owm bearing, and the passengers can make them spin on their own axis by actuating the central disk, in addition to the general rotation. Thus that roundabout offers either a leisurely ride or a terrific fast ride to the passengers. The spectator, for his part, enjoys a varied colourful picture.
