This item is a educational construction kit assembled from various materials (plastic, metal, etc.). Cement is required, but no painting is necessary.
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)
