A good way is to twist an iron wire tightly around the object and connect this with the zinc, for which a remnant of a battery zino is suitable, as it has a binding post Besides the simplicity of this process, it has the great advantage that the iron itself is not attacked in the least as long as the zinc is in good electrical contact ■with it.
