The zinc is more active than cooper, so the zinc is easy to lose electrons and come to the positive pole. The cooper comes to the negative pole. Saltwater is acting as the role of electrolyte. The electrolyte is a material that can conduct electricity.

The saltwater will be activated when mixed with acetic acid. When the copper and zinc bar are both put into the salt and acetic acid liquid, there will exit an electric voltage and the electricity will go from the copper bar to the zinc bar. So the clock can be in operation.
