Fill the bottles and connect the anodes en cathodes:

left bottle above: add 20 gr of copper sulphate
left bottle below: add 20 gr of zinc sulphate
center bottle above: add 20 gr of zinc sulphate
center bottle below: add 20 gr of copper sulphate
right bottle above: add 20 gr of copper sulphate
right bottle below: add 20 gr of zinc sulphate

Each bottle will produce around 2 volts.

When you have this prepared, connect the copper to the red wire, with zinc on the other side so you will have a + and - side. Put zinc to the dark wire and on the other end copper. Start in the first bottle with copper and the end in the next bottle (zinc) in the second bottle you start again with a red wire that will end in the next bottle and there you start again with a black wire. This will create the electric circuit.

(Make sure the clamp cables do not touch the water.)
