Today was the last day of Holland's "fun with electricity" class at the co-op. He had a great time building circuits and lighting up little bulbs. The last experiment had me holding a balloon that was popped when the teacher made an electrical connection.
When we got home he was still so excited about having the circuits he built at home that he built this circuit that lit a bulb and made a pinwheel turn. Here's a short video I took on my camera.
