Abstract: An apparatus and a system include a module configured to identify an object, and to provide audio and/or video content selected based on the identified object. The object is identified, and a portion of the content is selected based on the identified object. The object may be a toy, and the content may be selected to enhance a child's interest in learning and playing with the toy. The apparatus may be included in a system including the module and an identifier attached to the module, where the module is configured to identify the object by interfacing with the identifier, where the module is configured to select a portion of the content based on the identified object, and to play the content.

Abstract: The apparatus includes a rubber base with two inlets, a two-chamber ceramic crucible with two identical outlets, and a model of the jewelry item with two sprues connected to two separate tree stems, with each sprue connected to a separate stem thus ensuring flow of different colors or different metals. Simultaneous casting of two different metal alloys of different colors in two separate chambers of the crucible is achieved by using a specially constructed two-head torch.
