Alternatively, for those that are becoming paranoid about galvanic corrosion (like me!), one could always use a piece of copper wire, strip it, wrap it around a pen or something, and put it in the block. It would be best if it was as big as the channel though.
If that doesn't do anything, we could try my chain of inverted cones!
