My son planned to make experiment about Bolta battery. It is an assignment for summer vacation of his primary school. He wanted to do it when he read the book about Edison. And, I helped him.Bolta battery is very simple battery. 1 yen coin, 10 yen coin and paper which include salty water make electricity. As the electricity is very small, he used LED light for checking.
As a result, LED light brought. His experiment was succeeded. All I had done was buying items for the experiment.
I'm now helping his making report.
