Advice

  • You can replace the zinc coin with a galvanized steel nail.
  • If you can use a copper strip instead of the coin, the battery will work even better. You can push the strip even deeper into the cell. The cents and pennies minted after 1982 have only a very thin layer of surface copper, while the rest of the coin is zinc. So cents and pennies that date from before 1982 and some from 1982 have a higher concentration of copper. You can feel the difference by dropping the pennies on a hard surface. If you can use a copper strip you will get better results.
  • You can replace the voltmeter with the speaker of an old transistor radio.
  • Many other types of substitutions are possible - experiment.
  • This type of battery is called wet cell; normal batteries, on the other hand, are dry.

Warnings

  • When working with electricity, always be careful.
  • The electrical energy in a single cell is not particularly strong. To turn on a light bulb you will need several cells connected together (two or more cells form a battery).
