Device having at least one channel and at least two liquids

The embodiments relate to devices having at least one channel and at least two liquids, to a housing element and to a medical imaging apparatus. In order for the device to achieve a design effect by liquids, it is proposed that the device includes at least one channel, wherein the at least one channel has at least one first liquid including a first density and at least one second liquid including a second density, wherein the first density is different from the second density, wherein the at least one first liquid and the at least one second liquid are arranged at least partially inside the at least one channel and the at least one first liquid has a plurality of structures that are demarcated from the at least one second liquid and which, when acted upon by a force, execute a movement inside the at least one channel.
