Frank Einstein and the electro-finger, by Jon Scieszka
I think this was a good book. Frank Einstein made an electro-finger that got energy from other sources to produce energy. The book talked a lot about energy, so it was a little different from what I normally read. I would recommend it because it is a little bit different from other book that people read. I also liked the character Mr Chimp who was in the first Frank Einstein book I read too.
