A pair-of-siblings wanted to know, how much water anybody carries out when he gets off the swimming-pool (or bathtub). To answer this question the show-producers organized a great spectacle: 100 boys and girls - members of
Erster Kölner Schwimmverein - jumped into the water of approx. 10 square-meters pool, dived along the length and leave the pool at the other side. Every child repeated numerous times, so that over 1,450 kids were counted and more than 1,150 liters water gone. The result for one individual person is approx. 750 Milli-liters.
