This is great! You can also try this with other fruits and vegetables, like, All tip submissions are carefully reviewed before being published.

Yes, just make sure to connect them with a conductor. In that case, you need to increase the number of potatoes used to generate a more considerable amount of power.

It doesn’t matter what color your alligator clip leads are as long as they have clips on both ends. About halfway. The liquid in the potatoes is necessary for this experiment, so dried out potatoes will not work.

In that case, you need to increase the number of potatoes used to generate a more considerable amount of power.

Potato energy! The juices and liquids inside a potato make it an excellent electrolyte. When we connect those nails with the wire, we create an electrical circuit in which electrons are flowing and producing enough electricity to light up a lamp or a clock. So how can potatoes serve as an electrolyte?

At least two potatoes are needed to make a potato battery, but sometimes the electrical energy produced is not sufficient to light up a bulb. Young children should be supervised when performing this experiment.

What will you develop and learn by making the Potato Battery? Hence, it’s highly efficient.

Hence it forces the electrons to travel through the potato by separating zinc and copper and forms a complete circuit. Nails and wires can be sharp if handled incorrectly. The reason for this is historical – in time when this was decided, we didn’t know much about electrons and it stayed because of all the formulas that rely on it. ", "I did not know about electrical spuds!

If the voltage is very low, try moving the nails closer together.

Make sure the alligator clip is securely attached to both the nail and the lead. Thanks to all authors for creating a page that has been read 384,241 times.

Any wire is fine, the only thing that needs to be different is the metals you are inserting into the potato. ", "Very helpful in terms of how you explained the experiment.

Can a single Potato be used to light a Bulb? We already mentioned that all batteries have a positive and negative electrode or terminal. Now take your third copper wire, strip its end and wrap it around this screw.

No, aluminum is not magnetic, and it will not flow through the potato to the clock.

To make cleanup easier at the end, cover your work surface with newspaper or a plastic bag.
