Wooden batteries

Hereby I would like to introduce my latest toy concept: Wooden Batteries for kids on Rudolf Steiner schools ("Almost as cool as real batteries")

If you put one in place of a real one in a multi-battery device you will have a slightly lower voltage and longer life. Use for flashlights, kid's toys, or anything.
However you need to stick on a wire or aluminum tape from top to bottom. I have tried it in some devices.
