  • decorative objects that include water or other liquids such as so-called snow globes or indoor fountains, enjoy great popularity among consumers, since such objects may have decorative as well as sedative properties due to the resulting movements of the liquids.

Further, on the planar surface are sensors which, when in contact with the at least one drop, due to the different physical properties of the first and second liquid (eg electrical conductivity) generate a signal.
  • US 3 462 149 also relates to a game of skill, which consists of a hollow body comprising two chambers, which are connected to each other through an opening. In at least one of these two chambers further objects are provided, which can be brought through the opening due to the movement of the play object in the second chamber.

  • the pad further has a boundary.
  • the presence of such a boundary prevents the liquid present on the surface of the base from accidentally flowing away from the base due to, for example, a tilting movement.
  • the limitation is either produced in one piece with the pad or is additionally applied to the pad.
