A fascinating device that uses the natural acidity of fruit, and some vegetables, to operate its electronic clock.
Just insert the clocks metal feet into the fruit and watch its display spring to life. No batteries required, the electrical energy is generated via a chemical reaction within the fruit.
The Fruit Clock comes in a variety of colours and is suitable for youngsters from the ages of six upwards.
It can be used to demonstrate the the basic concepts of how a battery works, without the need of dangerous chemicals or and special equipment - other than a piece of fruit, and the Fruit Clock itself.

How does it work?
The science behind it is simple; the Fruit Clock works just like a car battery, where the metal feet act as the electrodes and the fruit provides the acid electrolyte in the form of a natural organic acid like citric acid. Acidic fruits like Oranges, Lemons, Grape Fruits and Tomatoes work best.
- Oxidation-reduction reactions
