I took apart a Staples Easy button toy to see how it worked. Its very simple; attached to a circuit board there is a resistor, a capacitor, a button, and a circular black object that looks like a glob. The board is attached to a speaker and battery. So, something is telling this toy to say "That was Easy" when the circuit is closed, so im guessing there is a microchip embedded in that odd circular black object. Is this indeed the chip, and if so does anyone know what this black thing/technique is called? Below is a link to a picture of the circuitboard. The object in question is at the top left.
