How to make a potato battery

YES YOU REALLY CAN MAKE A BATTERY OUT OF A POTATO!

I know that it sounds ridiculous but you really can make a battery out of a few spuds and here is a quirky project to show you how.

All you need is:

  • 3 large potatoes
  • A shiny coin
  • A galvanized steel nail
  • A multimeter - for testing
