Did you know you could power a light bulb with a potato? The chemical reactions that take place between two dissimilar metals and the juices in the potato create a small amount of voltage that can power a very small electrical device [source: MadSci].Follow the instructions below to make a potato-powered light bulb.
Make a potato battery from each variety and record how bright the light is from each potato on a scale of one to five, to see which type of potato makes the best battery. References PhysLink: How can a Potato be used to Light a Light Bulb?;
How to make a potato battery. All you need is a potato, penny, copper wire, and a galvanized nail. You can use several potatoes to power a small light bulb.
A potato battery project is the last in a series of fruit and veggie battery projects included on this site. Many versions are available, but unless you want to get fancy with the voltmeter, fruit batteries make great science projects for kids since they are both inexpensive and relatively easy to perform.
Potato Battery Driven LED: So, if you looked at my profile you would see that I like physics. When the challenge for “Potatoes” I just knew that I need to do a project that highlighted the lowly “Potato Battery”. So here is how to make a Potato Battery and have it light...

When you put copper and zinc electrodes in a potato, phosphoric acid in the potato reacts with the electrodes to generate electricity needed to light the bulb. While a potato-powered light bulb won't generate much light for a long period of time, it's enough to gently brighten a dark area while waiting for the lights to come back on.
Use your potato battery to light up an LED. Wrap the free wire at the coin end around the long leg of the LED and the free wire at the nail end around its short leg.
Students use potatoes to light an LED clock or light bulb as they learn how a battery works in a simple circuit. They also learn how chemical energy changes to electrical energy and get a better understanding of current, voltage and resistance concepts.
