Abstract: There is disclosed a novelty soap bar having disposed in the interior thereof a water-impermeable, preferably plastic, housing containing an electronic circuit including a switch for opening and closing the same and which is programed to send forth a visible signal, tone, melody or message when the switch is closed. In a modification the soap bar is employed in combination with a holder or soap dish and the circuit is actuated when the soap bar is removed from the holder. The circuit switch may be opened and closed by the presence and absence of a magnetic field from one or more magnets located on the holder, or may be a vibration sensitive or temperature sensitive switch. In a modification of the invention, the electronic circuit can be used in combination with a wash mitten.
