オーストラリアン ジオグラフィック フードパワーラボ

The setup is straightforward—my kids had the potato generating voltage within ten minutes, and the copper and zinc strips held up well through three different fruits. It's the rare kit that makes a science fair project feel like a magic trick, and they've already asked to test a lemon next.

The copper and zinc strips worked perfectly with a lemon to light up the LED, and my daughter spent over an hour experimenting with different fruits. A solid kit for teaching kids about circuits in a fun way.

My nephew was fascinated when we made a potato power a small clock—the copper and zinc strips are easy to handle. He spent the whole afternoon testing lemon, apple, and orange slices. It's a brilliant, hands-on way to learn about electricity.
