Step 6 Make zinc electrodes

as zinc is not easy solderable, we'll have to use some force here

1. process zinc plates with sanding paper
2. cut pieces approximately the same size as copper ones
3. make small in the top of every piece and bend them
5. prepare the wire in the same way as with copper electrodes
6. clamp the wire with zinc pieces using pliers
7. make the conductivity test

Why not use aluminum? It offers more than twice the anode potential, it's easier to find, and should be miscible with copper/tin based solder.
