- Is there energy hidden inside your pocket change? Convert pennies into make-shift batteries that can drive small current devices like LED's and calculators.
Many people have asked how long the green LED stayed on. Surprisingly, it was bright for 2-1/2 weeks before finally fizzling out!

Project History & More Info:
LEGALITIES: Some people have asked about the legality of treating pennies in this manner. The federal law states that there are exceptions made for use as "educational, amusement, novelty, jewelry, and similar purposes as long as the volumes treated and the nature of the treatment make it clear that such treatment is not intended as a means by which to profit solely from the value of the metal content of the coins." For more information, see: www.federalregister.gov/artic...
This is a wet-cell battery. Pennies newer than 1982 are nearly 98% Zinc.
The redox reaction between the copper and zinc metals allow electrons to flow and each cell provides around 0.6 volts of electric potential.
Here is how to light up an LED and power a calculator using some loose pocket change!
I found this link that helps explain the reaction and why it works: www.science.uwaterloo.ca/~cchi...
Basically, a galvanic cell consists of at least two half cells, a reduction cell and an oxidation cell. Chemical reactions in the two half cells provide the electrons for the galvanic cell operations. Copper ions gain electrons (reduced) while zinc ions give them up (oxidized). = (redox)
An electrolyte like salt water or vinegar helps get the metals into ions. Electrons flow through the electric conductors connecting the electrodes, as ions flow through the salt bridge.
The overall reaction of the galvanic cell is: Zn + Cu2+ = Zn2+ + Cu

Those things powered small electronics. But you powered the world.
Too bad he died 😭
indeed
Actually Volta did. This was done in the 1700’s. Lol
@@devinmounce1838 I don’t think you understand what he’s saying
Nice speech obama
Well? When did the light finally die out?
Legend has it that it's still shining to this day...
after 6 days :)
Bosnjak Bosanac In description he says 2-1/2 weeks
Tofufrikadelle my was go out for 6 days and was same like his maybe if you find better configuration
They added it to the Smithsonian
jung min choi same type?
If that green light is still on in 50 years, it will become a precious artifact.
There’s a lightbulb in a fire department that has been on since the beginning of the 20th century and it’s still on and working
@@normalnate3447 That makes sense because contrary to popular belief, light bulbs take a lot more damage when you turn them on and off all the time versus just leaving it on. When it goes from cold to hot immediately, it stresses the filament. However if the filament is just constantly glowing, it doesn't stress anywhere near as much. Although it still will go out eventually.
R.I.P to a true legend
What? He isn't dead lol
Keer Tett yeah he is
Wutttt???
Hey They just sent a video 1:30 hour ago!
Keer Tett yeah he is.
This is great! I use this regularly to recharge my electric car!
Lol

Grant, I love you videos and I have tryed many of your projects. I love doing these projects, and I even did this one! I had lost of fun with it and my Dad thought it was amazing. Thanks!
Who needs normal batteries when you've got science? (And Abraham Lincoln)
I much prefer this classic style video to what we get now

I'm a bit curious... did the penny battery with the green light on run out yet? if so, how long did it last?
I get the feeling this guy's going to be living it up during the apocalypse,
meanwhile everyone else is fighting over batteries.
The only problem our great great grandchildren will have if there is no apocalypse is finding a username that isn't taken already!!!

I think it's kinda awesome how you can put together this sort of stuff from things we consider everyday stuff.
This is probably one of my best survival hacks yet thank you for showing us this i appreciative
Quick question: If you're buying zinc washers up front, does it still matter what year the pennies were minted?
Ok, so this is a bit of a theoretical scenario, but could you use this technique while camping or something and get lost and use your gum-wrapper fire lighting technique?
Please like this comment so Grant can see it! Thx!
+Attack Zombies Another good question .
Yes u could
I love your experiments and creations! Well done on the content!
If I were to dip the cells in vinegar, would it short out the system or would it keep going? Also, how long did the LED last?
It was a great idea to use double-sided tape during sanding. We are using a file to expose the Zinc. My question is, where did you find the micro-Amp LED? I have been looking!!
To me, this makes no cents.
HARHARHARHAR
Ellaney 1 thank you, what a terrific audience
Hhogenrater
well, why don't you get it? zinc generates electricity or was it just a joke
Chirantan Bhat just a joke XD
That's so cool! I never thought just a bunch of pennies could make so much electricity!
It's mainly the vinegar cuz of the electrolytes in it
Grant Thompson - So would it be possible to take this penny battery to a higher level? like running something that needs way more power?
M Hayos technically yes, realistically no.
mathematically, yes
Physically, yes. Start collecting pennies now, the apocalypse is coming soon
Unlikely, since the battery becomes a greater resistor the bigger it gets. Eventually, I think, the current will get so slow that it won't be able to power anything.
Soulsphere001 yeah as the current running through will have to go to cells
Walks into math class with a bunch of pennies strapped to the back of your calculator
Legends say that the green LED is still lit.
Hey Mr. Thompson, I stumbled across your videos and found really interesting and cool. This one how ever really caught my attention. I tried it and it out and was really surprised. I was always interested in free energy so as another idea for a new video for you I thought of trying to create a small cost effective generator using neodymium magnets. it always runs and never stops.
how it work out for u
free energy is impossible
@@funnyduck4568 The Earth itself is a lump of energy. Hence, most energy we see is free.
i did the green light 1, mine died after like a year XD
Waifu Todoroki's really? I need to try then!
Seriously it how many pennies did you use
How many pennies did u use
Ten thousand!!!
Pennies!!
Does it work with steel instead of zink?
love your creations grant!
How long did the light last?
2.5 weeks
some say the light is still on to this day
well he said it fizzed out, look in the description if you don't believe me
Rosemary Caldwell its a joke mary...its a joke...
To this day, rumer has it that the light remains lit.
becuse using normal batterys is to mainstream
too mainstream
Grammar, too, must be too mainstream.
Too maincurrent*. Electricity, duh
because
Im from Israel.
Foregive my English.
Its really neat how you can make power from pennies!
Just wondering, if I made a 15v version of one of these would it eventually charge a flat car battery? like over the course of a year? Just curious.
...so how long did the LED bulb stay lit? lol
+Joshua Kim I wanna know too XD
2.5 weeks. it's in the description.
+boobam nope it's still on
How long did that green LED stay lit?
SCIENCE!
It lasted 2 and a half weeks until it died out. Wow
I've been watching your videos for years now! Keep it up!
this video was awesome. thank you for making it! How big is the biggest one you ever made?
Too bad coins in Germany don't really have Zinc in them...
God dammit Germany,nothing he can build I could build,because you either make it illegal or just don't let it happen! :/
xD
Remember 9/11? That's why it was frowned upon. They fear that some terrorist could use this to kill innocent people.
Use a washer (not the washer machine lol) a washer it's made of zinc or nickel I think. I just proved it with copper, a washer and vinegar and it works perfectly !
THIS ONE IS BRILLIANT! Will be ruining some pennies today...how long did the L.E.D. end up staying on?
two and a half weeks mate.
he said it in the description, it stayed up for 2 and a half weeks
We made these at my old job, and arts and crafts kind of place. Super cool!
Hero’s get remembered but legends never die

The best experiments for a science fair!!!!
Love these vids, Such simple yet cool ideas
Great job love the vids please do more like this they are very interesting
How many pennies would it take to power a 300 watt computer? (of course its a scrap computer) Since its dc I would need a power inverter but how would I even begin to calculate this? Yes, I'm aware its not practical but its just an experiment that I would love to try. Also, would I need to make up a bunch of penny cells and put them in parallel or series?
about 1000 pennys? xD
Crazy_Gaming lol thats a nice round number but something tells me its going to take a lotttttt more. Haha
Ha, then I need about 3500 to power mine!
Well, each penny gives you about 0.6V and 500µA (= 0.0005A). So you would actually need 1 million pennies. 0.6V * 0.0005A * 1 million = 300W. But the good news is you don't need an inverter. PC power supplies can run on AC or DC. You could make a stack of 333 pennies to get around 200V and then put 3000 of those stacks in parallel to get the current up to 1.5A
But why not try it with a cell phone instead? Then you'd only need 3000 pennies.
spider pig Finally! Thank you! Well as far as the cell phone goes ive see endless videos powering them. I need more of an awe factor. (i get bored very quickly, very lol) Anyway, Thank you again, i really needed some type of foundation to start with.
* starts building a low budget generator using this trick *
Nice and Simple project! Nice work! =)
Dude this is so cool you inspire me to make skateboards and to take blacksmithing classes even though i am only 14 intact yesterday was my birthday
An led doesn't use much power but that is awesome.
HEy, great videos, I must ask, how did it take the green light to suck up all the juice from your battery?
I was looking around for similar videos and this is the best one on making your own coin battery. You'd think there'd be stinking piles of them, but nope you have cornered the market.
Great Work Again Grant!
loved the calculator idea, im going to try thi out to impresss some friends
well this idea is worth a few cents
coooltroll Nub AYYYYYYYYYY
Corney
this is amazing! i wonder how many of these pennie batteries we would need to power an electric car? I'm sure its in the thousonds lol
But will it recharge?
I would think so, just replace the soaked cardboard
the real question is will it blend
ya
The reaction happenning is a flux of electrons from the copper to the zinc so no, it won't recharge unless you apply the same amount of electricity in the inverse way to undo the reaction, source this is a basic redox chemistry reaction and I'm studying chemichals engeneering
vinegar only acts as an acid solution to help the flux work
so does the copper run out or something
I'm Penny Battersby and I'm watching a video on watching a video on 'Penny Battery' because why not
😂😂😁😂😁😂😁
Thank you so much this really helps with drained calculators😀😝
Tried this and it was really fun, Thanks!
How strong is that electric current? Bout three pennies.
my one has 2.5 ma
SAURABH DHINGRA That's potential/voltage, not current.
mindstormmaster WTF he wrote amperes
Amperes is current, Volts is voltage
mindstormmaster mA = milliAmps, which is current so there was nothing wrong with saurabh dhingras comment
sooo... When did the LED go out?
2 and a half weeks later (it was marked in the description)
***** dang that's some power
***** HOLY CRAP!!
I was thinking that this could be done, glad to know it can be. It might be useful someday.
Why must the cardboard be soaked in vinegar? And roughly how long does the cell last? (I assume it vaires on the amount of pennies used?
... Is this legal!?? I want to try this, but I've heard of defacing currency.
It is perfectly legal. Defacing money for fraud isn't.
epohnopulse
unfortunately its not legal, www.dailyfinance.com/2012/05/11/should-you-melt-down-pennies-for-profit-not-u-s-pennies-but/
Does the United States still use pennies? Canada doesn't so I guess I have a reason now to make a MEGA battery! I wanna see a few BIG stacks that equal over 1,000 pennies to see if it can power a few household appliances. Or see how long it will power a 100w conventional light bulb!
YOU ARE A MAD-MAN!
MrPypap So I've been told a time or two. What's your reason for thinking I'm a mad-man? :P
a conventional light bulb works with AC-volt, a battery puts out DC-volt. so it won't work for a second
Okeanos86 A conventional bulb will work on either AC or DC. It's just a tungsten filament that heats up; it doesn't matter if the current is alternating or not. Light bulbs in cars ect work the same way and they are on DC. Bulbs with electronics however probably won't such as compact florescent.
sc0tte1 you're right, i was wrong :) (how many times have you seen this phrase in the internet? :P)
This is so cool, I can't wait to try it with my friends.
YOU ARE TOING TO TRY IT ON YOUR FRIENDS?
This is really cool. Can you make a huge battery that can even charge a phone?

This doesn't make Cents...
Praçality
It doesn't make cents, it makes volts :3
lol
Don't resist it, especially if you're ohmless, as it'll be futile.
My led lasted 6 weeks and I used 50 pennies
Legend has it, that the green light will never die because it’s a legend.
Made one a little different... instead of cardboard I used a blue shop towel. I got only 3.6 volts but still 2.5 under the load of an LED. These batteries tend to die when the viniger drys up. We will see how long mine will last.
whats the max power you can make?
another words if you keep adding pennys will you be able to power an air conditioner?
Maybe if you take out the capacitors it might work
Well it really depends in today’s world! There are units that use DC to run, but what type of A/C are you thinking of? A car unit, a window unit, a whole home forced air unit, I would imagine all could be powered by pennies. It’s just each example would need different setups to get each one a working model. And for how long are we talking about for these setups to run? You might be better off getting solar panels a bunch of car batteries and a power converter to run a window A/C then a penny battery, at least the solar can be recharged each day!
grant needs to make vids like this again... it not the same anywhere......
Do you mean : it's not the same anymore?
Why did this guy have to die. Well atleast he's making inventions on a better plane.
You should try using a higher concentration vinegar and use copper, zinc washers to see if you can produce more voltage and amps
its illegal to deface a coin with the queens face on it! how do i overcome this problem?
How long was the led on???
2.5 weeks
Legend has it that the led light is still shining till this day
May I ask? What type of chemical reaction it undergoes?
I looked it up, it is a redox reaction making a voltaic/galvanic cell.
That is so awesome!! I want to try it now!
I ran the numbers, you'd need about 2,941 of these cells to charge your cellphone -_-
legend says that the green light is still on!!!
Yup
I tried making this before but I didn't have the patience to sandpaper all the pennies but still to this day great video
You're so smart, I never even thought this could happen.
This project will only cost pennies (and some cardboard, and vinegar)
and the thing you want power to
Marius shalalvand And electrical tape
These homemade batteries are just pennies to the dollar.
