Physikalische Phänomene kann man auch in der Küchenspüle beobachten: Trifft ein Wasserstrahl auf dem Spülenboden auf, so fließt das Wasser um den Punkt herum, an dem es auftrifft, zunächst schnell ab. In einem bestimmten Abstand steigt der Wasserpegel jedoch sprunghaft an, weil sich die Fließgeschwindigkeit verringert. Dieser so genannte hydraulische Sprung kann, wenn der Spülenboden waagerecht und eben ist, sogar die Form eines exakten Kreises annehmen. Dass sich aus dieser Kreisform unter bestimmten Bedingungen allerdings auch Vielecke ausbilden, etwa Dreiecke, Fünfecke oder Achtecke, haben Forscher im Labor erst vor einigen Jahren entdeckt.
