How does it work?

The copper plates act as the positive electrodes of a battery. They are plated with a metal that is less reactive than zinc. When the copper plates and zinc plates are inserted into the lemon, a chemical reaction takes place. Electrons (extremely small particles with a negative charge) move from the zinc plates to the copper plates to form a current, thus activating the LCD watch. The lemon juice helps to conduct electricity. You can replace the lemon with a potato, a grapefruit or use soft drinks and see what effect they have. Put some zing in the old tick-tock with a lemon powered clock!

Discover the science of batteries by building a lemon-powered clock. Made using safe and high-quality materials, just add a lemon for a fun lesson in battery science. Included in the package are copper and zinc plates, wire, and a clock. Challenge your child’s imagination with 4M toys and kits.
