Use the same technology that Thomas Edison used, to record your own voice on a plastic cup -- and play it back! Replacing Edison's waxed pipe and stylus, the kit uses a plastic cup and a needle, but the end results are the same. Everything you'll need to put the kit together, including a motor, battery box, plastic cups, and even a needle, are included; you need only to provide a Phillips' head (+) screwdriver, cellophane tape, scissors, and one size D alkaline battery. A fabulous experiment for the whole family! Download the English-language instructions booklet. (PDF)
