How to Make a Potato Clock
- 1). Assemble your supplies. You'll need two common galvanized nails; three alligator clip/wire units - that is, alligator clips connected to one another with wire; two short pieces of heavy copper wire; a simple low-voltage LED clock unit; and two potatoes. Obtain a simple LED clock unit that functions from the power of a 1- to 2-volt, button-type battery.
- 2). Open the battery compartment and remove the battery.
- 3). Note that there is a positive (+) and a negative (-) terminal point where the battery was installed.
- 4). Identify the potatoes as number one and number two.
- 5). Insert one nail in each potato.
- 6). Insert one short piece of heavy copper wire in each potato, placing it as far from the nail as possible.
- 7). Use one alligator clip/wire to connect the copper wire inserted in potato one to the positive terminal in the clock unit.
- 8). Use one alligator clip/wire to link the nail in potato two to the negative terminal in the clock unit.
- 9). Use the final alligator clip/wire to link the nail in potato one to the copper wire in potato two.
