Discover the science of batteries by simply adding your own lemon to turn your fruit into a power source!

Use electrolysis to learn about batteries and how they work with this hands-on, easy to use kit. Simply add a lemon and watch the circuit come to life powering your very own clock!

It works as when the copper and zinc electrodes are inserted into the electrolyte – a solution that conducts electricity, in this case, the lemon – the zinc electrode undergoes an oxidation reaction and the copper electrode undergoes a reduction reaction. The zinc electrode releases electrons that move through the wires to the clock and the copper electrode. This current activates the display on the clock!

A brilliant gift set for a young, excited and inquisitive mind. Ideal to foster curiosity and encourage scientific learning on rainy days and a fantastic school holiday activity.

Contains 2x copper and 2x zinc electrodes, clock, wires and instructions.

The lemon can be replaced with a potato, grapefruit or even soft drinks.
