Materials

  • 1 potato
  • Shiny copper penny
  • Wire pliers or knife

Preparation

To prepare for the potato battery LED light, shine the penny so it will interact well with the potato.

Step-by-step Instructions

  1. Insert the ends of the copper penny and the galvanized wire most of the way into the potato. Make sure they are not touching each other. If they touch each other the battery will becoming 'shorted' which means you will have to start over.
  1. Put the Multimeter on a DC setting. Touch the red and black test leads to the galvanized wire and the copper penny in the potato. Take note of the reading. You will need 1.5V to light up the LED light.
  1. To increase voltage, create multiple potato batteries until the sum of their voltage exceeds 1.5V.
  1. Then, connect the potato batteries to each other using multiple red and black test leads. Once the potatoes are connected with the test leads, you should have one black end and one red end left. Connect these ends to the LED light's wire ends and the lights should turn on!
