How to Make Lemon Batteries!
Got some lemons? Let's make a lemon battery! With just a few household items, you can generate electricity and light an LED. Join in this hands-on activity to learn about electricity. It is great for all ages and cheap to build. You need 3x lemons, copper pennies, galvanized nails, copper wire, and an LED to light up.

FAQ, Tips & Issues building the Lemon Battery:
Top reasons why it doesn't light up an LED:
1) Your coins really should be made of 100% copper, meaning they should be minted before 1982. Coins minted after 1982 are copper plated zinc (2.5% copper, 97.5% zinc). I have had success with these current coins, however very unreliable success.
2) The copper pennies should be clean. Use steel wool or a brillo pad, or the rough side of a sponge and some vinegar to clean them.
ALTERNATIVELY: You can just use a good amount of copper wire inside the lemon instead of the copper pennies, but if you aren't using enough copper wire, your lemon battery won't generate enough current.
3) Your LED legs are facing the wrong direction.
4) Inside the lemon the copper pennies and zinc nails are touching.
5) The connection from copper wire to zinc nails isn't good.

Hey Jared Owen ! I watch your videos and beleive me they are amazing and I get satisfied after watching it as they solve my question about this confusing world. Thank you! 🇮🇳 Love from India 🇮🇳
This was my science project in 6th grade but I never made it work!! 12 lemons in and still no juice. I realize I might not have put enough pennies and most likely not wired them up correctly. Thanks for fixing my childhood!
Video looks really good. Awesome video!
I have just finished this experiment with my class and it worked perfectly thanks to your video! Thank you!
Q1. Galvanized nails and copper pennies can produce electricity, because of different reducing and oxidizing powers of zinc and copper (zinc is more reactive than copper, and easily gives away electrons, compared to copper). Role of lemon: to work as an electrolyte i.e. to transfer electrons from one electrode to other. Q2. Connecting batteries in series algebraically adds up the voltages of each battery, enough to light a LED. Although LED can work at really low voltages, but a single lemon battery generates even lower. Q3. LED or LightEmittingDiode is a semiconductor diode, more specifically forward biased p-n junction, in which recombination of millions electrons and holes is taking place every second (actually that is bond formation and not recombination, i think), realizing a lot of energy in form of EMWave or Light (of certain wavelength, controlled by material used and doping). these was your part, now my part :D Wooooowwwwwww!!! That's cool, on how you switched from conceptual science to practical science. Thank you!!! :) Also, I couldn't ask it on your last video, but how do a phone know how percentage of battery does it have?

Great responses! Yeah, over time the current decreases, and the power manager microchip in your smartphone measures that and interpolates a % depending on the current max vs current 'empty'. Max and empty aren't absolute values and they don't represent 100% of the lithium being in the carbon vs cobalt respectively, but rather its a %.

as far as i know, depending on the lithium ions that are present on the cathode ( carbon layers ).... or may be the free electrons that are present on the anode ( cobalt lager)... noting down the initial and final condition i.e 0% and 100%
Good one.
Your Videos are of incredible Quality! Nice Job, keep going like that :)
Thank you so much! I have a Physics tomorrow and this is the project we have to do. You really helped me, thank you so much. I hope there are still people like you who help to another people. Btw your videos are amazing! Keep going, good luck!❤️💜

You can use NE555 to make alternating segnals with high frequency and after with a transistor put the first copper coil (5 turns) arround the second coil (1000 turns to increase the voltage). You can do Tesla Coil easy with ΝΕ555 today.. 😃

Lemons can think too. These thinking lemons produce enough electricity to charge the LED. Be sensitive when you cut a lemon into half next time.
when does your next video coming...?

What factors have to be twisted to generate a higher current?

Making multiple lemon batteries and placing them in series will provide more current. Also you can add more metal surface area into each lemon.
Put two electrodes in an electrolyte solution you have a battery 😊
