While they were working on another hackwork (a plaster plaque commemorating a doctor, Gawlik, for the hospital in the town of Siewierz), KwieKulik made a series of Activities with mercury balls, which leaked from a broken thermometer. They arranged the balls in a similar way as in Activities with Dobromierz (1972-1974), in relation to some mathematical-logical operations. This Activity begins with a shot of a TVscreen because as the action occurred the TV was broadcasting a popular didactic science programme on set theory.
