  • Patent number: 5971827
    Abstract: A novelty soap bar is disclosed. The bar comprises an attractor module within a soap body made of substantially translucent or transparent soap, surrounding the attractor module. The attractor module comprises a water impermeable shell; an electronic, actuatable circuit within the shell adapted to cause emission of at least one of a visible and an audible signal, perceptible through the soap body; and a battery within the shell for providing energy to the circuit to cause emission of the visible signal. The module further comprises a light sensitive switch, mounted within said soap body to sense light exterior to said soap body, and interconnected with the circuit and the battery, to inhibit flow of current from the battery in the absence of light; and a motion sensitive switch interconnected with the circuit, to activate the circuit in response to sensing motion of the soap bar. The attractor module may be arranged to produce an animated sequence visible through the soap bar.
