Fruit Battery-Potato Clock Science Experiment Kit for DIY Home Teaching Toy, School Science Project an
Fruit Battery Clock with zinc and copper strips, a number of wires, electronic clock or LED plus potatoes or oranges and other fruits. First kneading the fruit to make it more loose so that the water flow more fast, plug in the two electrodes, connect the wire, install the diode or electronic clock on it
Features :-
Apple, orange, pineapple, potatoes, etc., can be made into fruit battery

Two or three fruit parts are all that's needed to create a working clock. No batteries required.
Ability training : intellectual development, hands-on brain, interest training, parent-child communication, interactive toys, and other abilities
The production of science and technology can magnify the imagination of the child and stimulate the children's ability to create and invent new things
Challenge your child's imagination with toys and kits.

Experimental purposes :-
The two Potato Clock allows you to generate enough electricity to run a digital clock using potatoes! Just push the zinc and copper electrodes into the potatoes causing an oxidation/reduction reaction that is converted to low voltage. Watch your child's delight and sense of accomplishment with the clock they create.
