A promotional display comprising a chamber having front and rear panels with inside and outside surfaces, for containing between expanses of the inside surfaces of the panels a first liquid. At least a portion of the outside surface of the front panel comprises a view surface which allows viewing of liquid flow inside the chamber. A liquid reservoir is positioned adjacent the chamber for containing a second liquid therein, which second liquid contrasts with and is not miscible with the first liquid. A restricted liquid flow path is located between the chamber and the reservoir, which allows flow of the second liquid into the chamber and across at least a portion of the view surface of the chamber. The chamber includes at least one recess formed in the outside of the front panel which extends the inside of the front panel substantially all the way to the inside surface of the back panel, so as to substantially cause any liquid which flows between the front and rear panels of the chamber in the area of the recess to flow around, rather than behind, the recess. An object, to which it is desired to attract the attention of a viewer of the display, is placed in the recess.
