  • 6 of 14: ... but according to the Captain's journal, silver works just as well as zinc.
  • 7 of 14: In Volta's first battery, the two metals were separated by flannel soaked in a weak acid.
  • 8 of 14: If you've not tried this experiment as a school science project, know that lemon juice works well as the weak acid.
