How to Make a Fruit Battery

The lemon battery experiment listed here is similar to the experiment of the first electrical battery, invented by Alessandro Volta in the year , where he used a brine solution. Listed below is a methodical explanation of the experiment. Jul 08, †Ј The copper and zinc metals act as positive and negative battery terminals (cathodes and anodes). The zinc metal reacts with the acidic lemon juice (mostly from citric acid) to produce zinc ions (Zn 2+) and electrons (2 e -). The zinc ions go into solution in .

Has your flashlight ever stopped working because the batteries were dead? Batteries are everywhereЧin our toys, in our cars, in our flashlights and cell phones. But how do they work? What makes them stop working? You can learn how to make a lemon battery to learn more about these very important devices. When you touched your tongue to just the copper wire, you most likely would not have noticed anything unusual.

When you touched your tongue to BOTH of the metal ends, you might have felt a tingle, or noticed a metallic taste. The tingle or metal taste you noticed shows that your lemon battery was generating an electric current. That means tiny electrons were moving across the surface of your tongue. The lemon battery you made is a type of battery called a voltaic battery. These types of batteries are made of two different metals, which amke as electrodesor places where electrons can enter or leave a battery.

In your case, the electrical current entered your tongue, which is why you felt a tingle. So why were we able to stick electrodes into a lemon and get a battery? All voltaic batteries need their metals to be placed in an electrolyte. An electrolyte is a substance that can carry electrical current when dissolved in water. The tiny bit of salt in your saliva makes your saliva an electrolyte, and the sour citric acid does the same thing for battegy juice.

Batteries stop working when there is not enough of the electrolyte to react with the metal or not enough metal left to react with the electrolyte. You can generate more electrical current by connecting multiple lemon batteries. Just make a second battery and connect the zinc or steel piece of one battery with the copper wire of the other battery using another piece of copper wire to act as a bridge. What is meant by oxygen debt can use your enlarged lemon battery to power a low-power device hattery a digital watch or calculator.

Remove the regular battery from the digital watch or calculator. Connect the zinc or iron electrode with the negative contact. Can you get the device to work? If you are looking to test a variable, try making batteries using different fruits and vegetables.

Which ones produce the biggest tingle on your tongue? Which ones generate the most electric current? How to make a citrus battery this to easily find it later.

Use the wire clippers to cut it to the same length as your copper wire. Use the sandpaper to rub out any rough spots in your wire or paperclip.

You united kingdom includes what countries going to be touching the wire ends to your tongue, so you want them to be smooth.

If you are using the zinc covered nail or piece, scratch it lightly with the sand paper to expose a fresh surface. Roll the lemon gently on a table to break the cell walls and loosen up the juice inside. The sour juice is needed for the chemical reaction that you are about to start. The fact that the juice is sour should give us some hints about what kind of chemicals batteey up lemon juice.

What do you think the sour flavor might tell us? Carefully stick the copper wire about 1 inch into the lemon. Make sure your tongue is moist with saliva how to make handmade birthday cards at home, or spit. Touch your tongue to the copper wire. Do you notice anything? The wires need to be close to each other because they will be swapping matter mxke the chemical reaction.

If they are too far apart, the matter might lose their way. Disclaimer and Safety Precautions Education. In addition, your access to Education. Warning is hereby given that not all Project Ideas are appropriate for all individuals or in all circumstances.

Use fruit to generate electricity for a light bulb

Nov 25, †Ј This video shows how to make a lemon battery using a lemon, a copper wire, and a zinc coated (galvanized) nail. The video also goes into how lemon batteries.

Last Updated: April 24, References Tested. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. The wikiHow Video Team also followed the article's instructions and verified that they work. This article has been viewed , times. Learn more Batteries are an essential part of everyday life. They allow you to carry electronic devices on the go without having to plug them into a wall outlet.

A battery is able to generate electricity by passing electrons between two different metals one positively charged and one negatively charged. The electrons create a current as they pass through a solution containing molecules that carry the charged particles back and forth between the two different metals. To create a battery from a lemon, roll the lemon on a hard surface to get the juices flowing.

Next, cut a small slit through the rind in the middle that's big enough to insert a copper penny about halfway. Insert the penny, then insert a nail about 2 centimeters away. They need to be inserted deep enough to touch the lemon's juices, but they can't touch each other. Then, using the end clips of a voltmeter, attach one clip to the nail and the other to the penny. You'll see a small increase in voltage on the voltmeter -- you just created a single-cell battery!

Tips and Warnings. Things You'll Need. Related Articles. Article Summary. Method 1 of Gather your materials. To make a lemon battery you will need a copper penny, a galvanized nail, a lemon 10 total , a knife, and a voltmeter.

Adult supervision is recommended, especially while handling the knife. Rinse the penny with a light detergent to ensure you are working with a clean surface. If you have one, a strip of copper will work better than just a penny.

Galvanized nails have a zinc coating that is important to this experiment. A voltmeter can be purchased at a hardware or home improvement store. Squeeze the lemon without breaking its skin. You can roll the lemon on a table applying a small amount of downward pressure.

The squeezing action releases the juices inside the lemon needed for the battery to work. The acidity of the juice in a lemon makes it ideal for this sort of chemical reaction. It contains the solution of molecules necessary to carry electric current between the two metal ends of a battery. Cut a small slit through the rind in the middle of the lemon. The slit needs to be large enough to insert the copper penny about halfway into the lemon.

Adult supervision is recommended for this step. Insert the penny and the nail into the lemon. The nail should be pushed into the lemon about 2 centimeters away from the penny. These items will serve as the positive and negative ends of your battery.

The metals need to be close to each other in order for the necessary chemical reaction to take place. Make sure the penny and the nail are deep enough to be in contact with the juice of the lemon. Attach the voltmeter clips to the nail and penny.

Using the end clips of the voltmeter, attach one clip to the nail and the other clip to the penny. You should see a small increase in voltage on the voltmeter. If the voltmeter is reading a negative value, simply switch the clips on the nail and penny and it should change to a positive voltage. If the voltage is very low, try moving the nail closer to the penny. Method 2 of Gather your tools. A multi-cell battery is when you connect multiple batteries together.

In this case, you will link multiple lemon batteries together. To make a multi-cell lemon battery you will need four copper pennies, four galvanized nails, four lemons, a knife, 15 inches of copper wire, wire cutters, a ruler, and a voltmeter.

Any lemon will do, but a lemon with a thinner rind will make a better battery. Adult supervision is strongly recommended, particularly when using the knife. Clean the penny with a light detergent to maintain a clean working surface. Galvanized nails have a zinc coating that is important to this experiment [8] X Research source and can be found at a local hardware or home improvement store.

Squeeze the lemons without breaking their skin. Gently roll each lemon across a tabletop, applying a small amount of downward pressure. Squeezing the lemons in this way releases the juices inside the lemon needed for the battery to work. The molecules in the juice will carry the electric current between the two metal ends of the battery. Cut the copper wire into five 3-inch pieces. Measure out 3-inch pieces of wire and snip them using the wire cutters.

Connect a penny and a nail with one piece of wire. You are going to make copper-wrapped nail and penny pairs. Take a bit of wire and wrap it a few times around the penny and then take the other end and wrap it around the top of the nail. The penny and nail will be inserted into separate lemons so be sure to leave enough space about 1. The battery will not function as well without proper contact between each connection. You should have three penny and nail pairs when you are finished.

Wrap a piece of wire around just one penny and one nail. The battery will begin with a single copper-wrapped penny and end with a single copper-wrapped nail.

Just as you did before, take a piece of wire and wrap it a few times around a penny. Using a separate piece of wire, wrap that a few times around the top of the nail. The slit should be large enough to insert the copper penny about halfway into the lemon. Insert the single copper-wrapped penny and nail into the first and last lemons, respectively. Line up all four of your lemons and choose one to be the first and one to be the last.

Stick the copper-wrapped penny into the slit you cut into the top of the first lemon in the chain. Insert the copper-wrapped nail into the last lemon in the chain. It is not super important that all of your lemons stay lined up as long as the single penny and nail are stuck into separate lemons.

Insert the copper-wrapped penny and nail pairs into separate lemons. Each lemon will ultimately have one penny and one nail sticking out of it. The first lemon in the chain will already have a penny, so stick the nail end of a pair into the first lemon. The second lemon will get the penny from that pair. The second lemon will also get the nail from the second pair of copper-wrapped pennies and nails.

Be careful not to have the nail and penny touch within each lemon. Attach the voltmeter clips to the free end wires. Using the end clips of the voltmeter, attach one clip to the copper wire attached to the nail and the other clip to the copper wire attached to the penny. You should see an increase in the voltage reading on the voltmeter. If the voltmeter is reading a negative value, simply switch the clips between the nail and the penny and it should change to a positive voltage.
