    Discover the science batteries with this cool mini-experiment! Simply add your own lemon to turn this kit into an amazing lemon-powered clock. You can even use a potato, grapefruit or a soft-drink to see what effect they have. Lemon required, not included. For ages over 5 years.

    How does it work? The copper plates act like the positive electrodes of a battery. They are plated with a metal which is less reactive than zinc. When the plates are inserted into the lemon, a chemical reaction occurs. Electrons (atomic 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 conducts electricity.
