We're going to learn how to use the energy stored in fruit and veggies to run a clock, light, and other cool stuff.  Are you ready?

This webpage has all the information you need to complete a Science Fair Project, including instructional step-by-step video, documentation, required forms, experimentation tips and tricks, and how to squeeze your great idea into the scientific method.

    The best thing would be to use a LED (Light Emitting Diode). It requires 2.2volt in order to glow. The current from these batteries is very low, so a current limiting resistor shouldn’t be necessary. Click here to order LEDs from Jameco.com.

    My daughter did the fruit batteries experiment last year to determine which one produced the most voltage and wants to extrapolate on it this year for the science fair. What type of light bulb should be used if we want to take the experiment to the next level? Such as, how many lemons are needed to light a light bulb? Thanks!

  3. This is an experiment, because you’ll be discovering the voltage provided by different kinds of produce. But I recommend discussing your plans with your teacher to make sure this project qualifies.

  4. Is this project an experiment or a demonstration? My teacher says I need to have an experiment project.

    This is perfect! Our homeschool science fair is coming up and my kids are going to love this project! My older daughter built what she calls a “flyhicle” out of a laundry basket, using a bunch of cords from the cord drawer (basically a home for extra cords and wires that we don’t have an immediate use for) in my desk. She wove all those cords and wires together and stuck them in pieces of fruits and veggies,and made construction paper pouches with tape to hold them to the side of the basket. She said that it was the first fruit and veggie powered “green flying machine.”She was frustrated, though, that it didn’t actually work. SO, making an actual battery that WORKS out of fruits and veggies will thrill her. Now if we can just figure out how to get the laundry basket to fly …..

    Sounds like that might be fun.

    sounds cool is it fun?

    what if you could not find a multimeter with 20DC V is it ok to use 25DC V?
