Stick a nail into one end of each potato. Stick a copper coin into the other end of each. You can use a knife to cut a slit to squeeze in the coin. Cut the wire into four pieces, each about 6 inches (15 cm). Make sure it is copper wire. If it is covered with a plastic casing, please strip it away at the ends.


2. Insert one nail into the end of each potato. 3. Insert one short piece of the copper wire into each potato, as far away from the nail as possible. 4. Use one alligator-clipped wire to connect to the copper wire in one potato, and clip the other end to the posive (+) terminal in the clock’s baery compartment. 5.


How to make a potato battery YES YOU REALLY CAN MAKE A BATTERY OUT OF A POTATO!I know that it sounds ridiculous but you really can make a battery out of a few spuds and here is a quirky project to show you how. It takes an ordinary household potato and turns it into a voltage source, powerful enough to drive an LED light bulb.All you need is:3 large potatoesA shiny coinA galvanized steel nailA ...

How to Make a Potato Battery 1. Push a piece of copper wire and a zinc-plated (galvanized) nail into the potato to act as the electrodes in this experiment. The two objects should be close together, but don’t let them touch. 2. Connect the other end of the copper wire to one terminal of the LED or a connecting cable as ...


Connect wire from first potato to the nail of second potato and wire from secant potato to the nail on third potato. Svitch multimeter to voltage reading and make sure that the scale set to read 0-10 volt range. This is pretty much it. Now you can start measuring voltage of your brand new potato battery.


The total theoretical voltage across the potato cell is therefore 2.89 V in sufficient oxygen (Aluminium/air battery), or 1.66 V in insufficient oxygen (Aluminium/Hydrogen battery). This also works with lemons, tomatoes, apples and other fruits! back


And that’s how you make a potato battery, without the potato! Amazingly, 24 hours later, its still going strong and I can’t help but wonder, “How long will this thing last?” (Update: It lasted about 72.5 hours!) More Details on How Penny Batteries Work.


Dec 30, 2017 - Potato battery science project: Investigate how to make batteries out of potatoes using zinc and copper electrodes, connect them in series and in parallel, and use them to power a buzzer and LED.


Gather materials and make copies of the Make a Battery Worksheet. With the Students. Divide the class into teams of two or three students each. Hand out the materials. Direct groups to carefully place the zinc nails and copper pennies into the potato. Make sure the two different metals do not touch each other in the potato (see Figure 1).


The scientific approach would be to build the potato battery, measure the output and see whether it's enough to replace the battery in an RC car. You've already done some research so I think you know the answer - unfortunately a single potato won't come close to replacing an RC car battery pack. A potato is the rough equivalent to a single AA ...
