➡️ Try It Yourself:
All you need is some Aluminum cola/pop cans or pipe, and copper wire or pipes. You can also use Zinc instead of the Aluminum. The more salt or acid you put in the water, the stronger the battery will be but, the faster it will corrode and break down the metals. Please post your results in the comments so we can see your project!
➡️ Helpful Battery Information:
The same principles apply to making and lemon battery or potato battery. You just need two dissimilar metals like copper and aluminum, used in this video, and an electrolyte like sodium (table salt) or Epsom salts, or an acid like lemon juice, vinegar, or other common battery acid. Making your own battery is actually fairly simple. You just need two metals separated buy a thin insulator like paper, or by your electrolyte fluid. Then connect the positive and negative terminals to each metal. The more surface area you have touching the electrolyte or acid, the more amps you get. The more of these cells that you wire together in series, the more voltage you get. 12 volt car batteries for example, have hundreds of thin lead plates inside each cell. Then each cell inside the car battery is wired together in series to increase voltage. Those plates are what hold the charge. Each pole on the battery is connected to the positive or negative end the chain of battery cells, wired in series, inside the battery. Another example is a 9-volt battery used for devices around the home, such as smoke alarms, remote controls for RC cars, walkie talkies, and much more. These 9 volt batteries usually have six cells inside of them that equal about 1.5 volts each to give you the 9 volts required for your device.

THIS IS THE STUFF WE SHOULD HAVE BEEN LEARNING IN SCHOOL: Demonstrating general chemistry and physics put to practical usage is so much better than the lab experiments they had us doing in our college courses. I have no idea the stuff I was combining nor for what purpose other than it was the curriculum requirement. We had to do these experiments if we wanted to get at least a passing grade in the course.

If you take Washing Soda Na2CO3 you will get at least double of this cell voltage... If you will use Carbon rods from Zinc carbon Batteries instead of the coper spiral you can get 1.3 Volts with Na2CO3 if your can is from Aluminium...
Is this experiment really work?

Nice kids project. Tip. All Alu cans are coated inside, rough up the inside of the can with a wire brush on a drill to maximise the alu surface area, increase the copper wire diameter and amount of coils, more copper equals more amps.
Great tip Mr Freddie! Thank you for the suggestion. I will definitely rough up the inside of the cans next time. Please share and subscribe!
Great project! A few improvement suggestions: Get rid of the cardboard. Replace the bottom insulator with something more robust (plastic, plexiglass, etc.). Do not put any insulator around the can at all, that reduces the contact area increasing the battery's internal resistance affecting the amperage the battery can deliver. Sand alone should prevent the shorts from happening. To further reduce internal resistance give the inside of the cans thorough sanding and also make the copper as large of a surface as practicable (eg a few serpentine twists or use foil instead of wire). Cover the cans with lids to reduce electrolyte evaporation. Use a mild acid instead of salt. Good luck.
Hi Bob, thanks for the suggestions. I am wondering .. If we go and use alum foil and copper foil [like a sandwich], would that work ? sounds like the better conditions, bigger surface area all around. Questions :
1. The sand is there to keep the copper from touching the other terminal, right ? It does not involve itself in the chemical reaction, correct ? while the granules allow the liquid and ions to go through to perform the electrical currents ? If all this is correct, then can we use gauze or cotton to separate and make the sandwich ?
2. Is there anything in this being the consumable items ? Eventually the metals will be eaten away ?
Thank you for the comment Bob and for the suggestions! Please Subscribe if you haven't already, I would appreciate your feedback on future projects. I did put some vinegar in later which did seem to increase output to the light, however the cans started getting holes in them shortly after. I should have put them in seal-able plastic containers to prevent evaporation and leaking. Would have keep them running longer.
Hi Kingston, thanks for your comment. Please Subscribe if you haven't already!
1. I just used the sand to hold the copper wire in place. Unless your sand has any acidic or electrolyte properties in it, the sand should not play a role in the chemical reaction. Yes I would think you can use gauze or cotton. As long as the two metals do not touch, which would cause a short.
2. The Aluminum is being consumed in this type of battery. Holes start to appear in the Aluminum cans after several weeks.

The inside lining of soda cans, if sanded off, should give you 0.9 volts. I did it without first sanding it and then after sanding it. It was 15% improvement in voltage.
Awesome Homayoun thank you! I will try that on the next version. Please share and subscribe!
What grit sand paper?
Yeah there is a thin film of plastic inside aluminum cans so sanding it makes sense
i didn't think it would work without a sanding at all
@Dan Lapain it's thin enough to allow conduction, just not as efficient as it can be...

@@GoogleUserNova1680 what do you mean charge them? How do I do that. I want to make a rechargeable 13v supply that gives like 30Amps that can work alongside a power Supply
I made these and after about 3 days I had salt water all over ..the salt caused holes the sides of the cans...Made different ones using large plastic jars , galvanized pieces of metal, larger gage copper wire, and epsom salts instead of salt and distilled water .
Worked a little better...no leaks.. like batteries with electrolyte of some water mix, the water evaporates and add only distilled water to prevent build up of minerals in tap water. that cause batteries to deteriorate..

Amazing, thanks for sharing, with that 5.26 voltage you will be able to use a Boost converter and run higher voltage devices, it's a live saver for sure
You're welcome. I could have gotten away with making a few less cells and using a boost converter to get it up to the 5 volts needed but figured I would just run it straight through for this test. Thanks for subscribing!
No. It's about 2 W. Will charge your phone in about 10 hrs. The current is too low.
should ahve use mutistrain wire for MAX effect rather then a single one
Thank you for the tip!
I live to see Experiments like these. How can I do something like this that can get like 10 amps and be rechargeable
Nice idea but few improvements rather than using copper and tin use carbon rod and zinc plate which will produce 1.5 volts each
Interesting suggestion I will have to try that. Thank you for watching and commenting, please share and subscribe!
Pretty neat!

Try to connect a Jule thief to this circuit, theoretically it should amplify the amperage, therefore you could have a brighter LED
Great idea! I would need to construct one first. Thank you for the suggestion! Please SHARE and SUBSCRIBE!
I wonder if these alum can batteries would of lasted longer had you used silicone sheeting or plastic for insulation. Thanks for sharing.
You need the "Bare" aluminum since that is your Negative.

This is so creative. Thank you. :) If I thicken the can and make it smaller, will there a difference on the voltage and amp? I want to do eco-friendly small and little bit more voltaged battery. Do you have any suggestion or advice? Thank you again.
Hi Urnaa, thank so much for watching and commenting! More surface area in contact with the saltwater or vinegar would give you more amperage, so more copper wire in the coil inside tthe can should work. The voltage ⚡ you would have to get a different metal probably. Aluminum and Copper only produce up to a certain voltage. Please share my videos and subscribe!

you'll get more power if you remove the plastic liner from the can, but you'll oxidize the hell out of it, shortening the life of your battery, this is also a great way to create hydrogen gas

Basic science. As a kid I made batteries using copper wire and zinc-coated roofing nails in salt water or powdered citrus drink: They produced 1/2 of a volt and was totally unusable in powering anything larger than a toy car motor. And was unable to power an incandescent flashlight bulb. Even like this, It cannot large amounts of power.
Hi David, thank you for watching and commenting! I appreciate you sharing your past experiments. Please SHARE and SUBSCRIBE!
Can you specify the link on the flashlight head ? or where to buy it? Thankss Also on the Sand so that I can know the volume per can like per grams and what kind of sand to use because it may affect the result. Where can I buy the sand?
Of course here is the link. It isan Ozark Trail brand mini flashlight. www.walmart.com/ip/Ozark-Trail-Mini-Flashlight-in-Assorted-Colors/34350005
This would be good for when I get hit by hurricane and don't have power for lights in the house! I missed something in there. Will go back and watch again!
Hi Donald, thanks for watching and commenting! It would be fairly dim unless you get a much brighter LED. You would probably need a few more cells in parallel to increase the amps and brightness. Please share my videos and subscribe! I love interacting with my viewers.
I really love the creative stuff...I watch alot of these types of videos...are these able to recharge?
Hi Robert, thank you for watching and commenting. This battery is not rechargeable. Once the aluminum is gone, or the connection breaks because of decay like mine, it is done. Please share and subscribe!

Hi Peace Lilly, thank you for watching. Yes there is a follow-up video here it is... ruclips.net/video/DRVzPqgp10c/видео.html
Let me know what you think?
I would be curious to understand what you can turn on with a battery of this type, a computer, TV, other? Thank you
This battery is very low amperage and can only power small LEDs or possibly calculators or other small appliances. Might be able to trickle charge a smartphone very slowly at this amperage. Thank you for commenting and watching, please share and subscribe!

Thanks for the comment! You can get more amperage by using a stronger acid like vinegar or battery acid from a battery supply company. Please share the video and subscribe!
Do you know how to produce electricity using salt water, coper soda can
I like how the can it's self acts as the anode but you should insulate the outside of the can not the inside

I feel like you could make these much stronger for the amount of space in a soda can. Maybe by adding citric acid or Gatorade to the battery instead of salt water.
Thanks for the idea! I will have to try that on the next one. Please share and subscribe!
Yes! Every one knows Gatorade has electrolytes. I saw it in a movie!
The four best DIY, safe battery electrolytes:
citric acid (C6H8O7) lemon, lime, orange, grapefruit, tomato juices
acetic acid (CH3COOH) vinegar (4% to 8% acetic acid), pickles
phosphoric acid (H3PO4) some soft drinks (e.g. Coke), potatoes
salt water tap water and table salt (NaCl)
Phosphoric acid can be recharged electrically, but not many times- like, 3-5 usually with ~15% capacity loss each time. They used these for Rechargeable Alkaline-Manganese (RAM) batteries back in the day before Lithiu, NiMH and NiCD.

looks good how long with they stay lit. you might charge a big capacitor.
Hi Joseph, they stayed lit for a week or two at a time till the cells dried out. Then I just refilled them again and with a bit of water and it would keep running for a few more weeks. It got a little dimmer each time because the electrons were being used up in the chemical to electrical reaction. The holes in the cans are shown in the update video. Please give this video a share on social media or reddit if you can. I would greatly appreciate it! Thank you for your comment!
Removing the organic coating inside the aluminum would help. The issue with this cell is that the sides will pit corrode and leak.
Hi Eddie, very true. I will remove the coating next time, and seal the outside with a plastic of some kind. If you like the videos please share and subscribe! Thank you for watching and commenting!

love it! i can use as reference for my project,
btw i like the music, what's the title?
What if you mix half of the sand with soda can pull tabs (sanded down if applicable) randomly distributed throughout the inside of the can?
How about if you crush full size cans with a can crusher and layer them in with the sand, and if it makes a difference, have the copper coil through each layer in spirals working from the outside-in then going through the middle of the next aluminum can disc then spiraling out, repeat.
good point i think this will give a better result.......

Use plaster my only thought on this is that you should make a sealed version and you can make enough smaller ones to power something and don’t use play sand use very very small glass beads because there’s iron in playsand and the salt water will cause rust to form

Hi My son tried it and was able to produced 3.5 volts on 9 cans but unable to power up a 2.2volts light from an old flashlight. Light works when we are using a 2pcs of AA 1.5v battery. Any other suggestions?
Hi Alan, thanks for commenting. That is great your son tested this out. If it was an LED light he will want to make sure he tries the positive and negative both ways LEDs only work in one direction. If it is an incandescent light bulb it might not work, because this produces a very small amount of current (amps). AA batteries can produce much more current. Please reply back and let me know if he gets it working! Please share and subscribe! - Danny

That's awesome Allan! Glad I could help. Thank you for watching and sharing my videos. - Danny
Well done! This is a real video, not a stupid fake. If you look at the activity series chart, you will see that aluminum is very reactive and copper is not very reactive. The difference is what makes a cell produce electricity. This also means the aluminum will eventually get eaten away. Your current is influenced by surface area of metal, as you correctly said, but also what chemicals the metals have to react with. I am no chemist, but have read a lot about historic batteries and modern batteries, and I do understand a few of the reactions involved. You might get more current or voltage or both if you add copper sulfate to your electrolyte. I am only guessing here, but I think the copper will deposit on your copper wire, and the sulfur will join up with the sodium from the salt to attack the aluminum and make sodium aluminum sulfate. I think that is the stuff we call alum. The chlorine from the salt may also attack the aluminum and give you aluminum chloride or it may unite with the hydrogen in the water, which will make hydrochloric acid. Either way, be careful, because these are not nice chemicals. And they may very well make holes in your cans. Put the rig in a litter box to catch any pee from the cells.
Thank you for the very detailed comment and great ideas! 💡 Yes always be careful when playing with chemicals. Please give this video a share and remember to subscribe!
I am currently dong this for my School research, can you tell me which one is the anode and cathode?

Came to leave a comment about the lining in soda cans but see others have already mentioned it. Another cool experiment might be to coat the can with magnesium and use a carbon rod for an anode instead of copper. It might bump you up to 2 volts per can. And then try adding different liquid solutions of salts or acids to the dirt to see if it might improve v0ltage.

Hello, may I have the list of materials used per can, I need it urgently. As well I input you on our acknowledgement on my research paper.
Hi Hokage, Of course I would be happy to. Per can there is one aluminum soda can (lightly sanded with sand paper), one round cardboard insulator for the bottom of the can, one thin sheet of cardboard insulator to wrap around the inside of the can, about 6-8 inches of 12 gauge copper wire wrapped into a coil, and one soda can full of play sand, a salt water to fill the can until sand is fully saturated. Then smaller gauge lead wires to connect copper coil from one can (cell) to aluminum can of the next cell, all the way down the chain. By the end you should have one small wire on the copper coil of the first cell and one wire on the aluminum can of the last cell. Please let me know if you have any other questions and please SHARE and SUBSCRIBE! - Danny
Mind blowing wow
Hi Usha, thanks for watching and commenting! Glad you liked the video please SHARE and Subscribe!
doesnt the can touching the water and water touching the copper mess it up, like touching hot and ground wires together?
Thanks for the comment KC, to my understanding no, that doesn't short the circuit out. You can put a piece of Copper and a piece of Aluminum or Zinc in the same glass beaker filled with an electrolyte (acid or salt water) and they will build up charge on the to different metals waiting to be connected to a circuit.

Could you make a 24amp battery with this? If so how long would it last do you reckon?
Good question! Thanks for watching 👀 ! I reckon it would last for a few week's depending on how much you use it. If you could make a 24amp battery you would need many plates/sheets of aluminum to increase the surface area enough to produce high amperage. Probably also sheets of copper, which would be expensive. Since my setup was just in series with a single cell in each it was only about 0.5v and a few milliamps for each cell. If you would like to try a larger version I would love to see your results.

Is this kind battery rechargeable? This is an amazing video.
It might take an initial charge but, would not be rechargeable since it is a primary battery. Primary batteries degrade the materials they are made from to exchange the electrons. Similar to a standard alkaline battery. Thank you for watching and commenting. Please SHARE the video, LIKE, and SUBSCRIBE!
@@SourcePortEntertainment now I understand. thank you.
You cant really get an acurate amperage test that way. Current is a measurement of electrons flowing through a load so you need to put a load on something like an led light and place probes in series on the hot side of the led light. Cool video though thanks for sharing. It gave me a few ideas of some stuff to try to maybe increase the amp hour capacity of something similar
Thank you Carl! I am gladyou enjoyed the video. I learned the properly way to measure amperage after the fact. I appreciate your comment. Please feel free to comment on some other videos and SHARE and SUBSCRIBE!
There's absolutely no evidence whatsoever that electrons, or anything else for that matter, flows through a wire. The evidence seems to suggest that what some call a flow is actually a field perturbation, which makes much more sense

Does the coil need to be curled up and straight? Or can it be curled up only or twisted?
The reason for the coil is just to get more copper surface area in contact with the electrolyte. Better amperage that way. Could Be twisted too but more copper in contact with the salt water solution is what is needed. Thanks for the comment. Please share and subscribe!

Depends on the DC motor and the volts/amps needed to run it. If you have a small 1.5v DC motor you would need at least 3 (0.5v) cells to meet the voltage requirement. It would probably spin fairly slowly with only a few milliamps that the cells are running at. Please share and subscribe!
Instead of cans use buckets and more copper. Do you think it would produce a lot more power. Looking at this, Could i bury copper on the beach and get a result. Thanx great vid.
The more surface area the better the amperage. So yes it should increase. Thanks for watching and commenting! Please SHARE and SUBSCRIBE!
That's called a earth battery, you can sink rods in the ground . you have to have the same thing, you have to have copper rods and tin rods. but yes you can't stick them in the ground and get power . but you will get nowhere near the same amount of power as you will get out of building a battery the way he just built one ... but there are people that build earth batteries . (low power) but I think myself it takes up way too much land space, too many rods to be worth anything. because you will get very low power from the earth battery.
You should use a wire screen over the spring and real battery aid from the auto part store. battery aid cost $10 a pint
Nice thanks for the tip Robert! Please subscribe and share the video.
awesome video, like and subscribed.... :D
Hey Renaldo, thank so much for watching, liking, and subscribing! More videos to come!
Was there vinegar in the original experiment? Also, is there any special instruction for proper disposal of these cans, and their contents, once they're finished?
It was just salt water to start, then I added a bit of vinegar to increase the amps. The LEDs started to get very dim after a week or two. I don't have an instructions for proper disposal. I think it is still just aluminum and copper with a few less electrons. Anybody else have any tips or insight?
Can add vinegar .
Should also use plastic bottles and put iron catod and zinc anod as well .
It'll give you more volts and ampers
Thank you for the tip. Will try that in the next version. Please share this video and subscribe!
So what your saying is…. If i pound this 24 pack of Dr Pepper and make 24 batteries i can make a 12 volt battery to power lights in my house when power goes out 🤔 i wonder if it would be enough to power a short wave radio for any period of time.. maybe if i sand off the coating on the copper and double the coil to double the mah. Now you got me thinking
Yes that is what I'm saying Mike! And that is awesome! 😜 Thanks for watching and commenting! Please SHARE and SUBSCRIBE!
What is the reason why you use sand, and card board? Base from what I've learn so far copper, zinc and acid can make electricity. I want to learn :D
Hi Leo, thanks for the comment. I just use the cardboard and sand to help stabilize the copper wire, and prevent it from directly touching the aluminum and shorting out. Please share and subscribe! - Danny
I'm following this tutorial for a project, and I was just wondering, would rice work as a substitute for the sand? Also, would the voltage increase if I used an acid like lemon juice or vinegar instead of salt water?
Hi Liana, I think rice should work just fine, since I'm just using it in this video to separate the copper from the aluminum further. If you used an acid like lemon juice or vinegar it will give you more amperage not necessarily More Voltage. Make sure you lightly sand the inside of the cans before you fill them. Also make sure you put some kind of plastic container or water bottle around each can, to prevent leaking your electrolyte out all over. They will degrade faster if you use a stronger acid like lemon juice or vinegar. Please let me know your results. Thank you for watching and commenting please share and subscribe!
Great idea this will need some testing! Thanks for watching and commenting, please SUBSCRIBE!
Is it a cooked rice or uncooked rice
@@SourcePortEntertainment is it a cooked rice or uncooked rice?
Hi Ebenezer, I have not had a chance to try the rice idea. Thank you for commenting.
have you tried recharging?
Can I ask a question?? I'm also using soda cans as battery but what are some other alternatives for the saltwater and dirt? We were tasked to make a alternative light source and I thought using some aluminum cans would be a great idea.
Hi Miki-kun, thanks for watching and for your comment. You can also use aluminum and graphite pencil core, or aluminum and a nail coated in zinc (galvanized) those also work. Good luck with your project! Please SHARE the video if you enjoyed it.
@@SourcePortEntertainment oh okay thank you so much!
Put the paper tube around your copper coil instead of the outside of the can and fill the outside of the tube with shredded/powdered aluminum instead of sand. You'll get much better performance.
+Laurence Perkins awesome suggestion thank you! Please share the video if you liked this project, and subscribe so you don't miss the next version.
Hi Laurence, do you have an example of that you could send me a link to? Thanks! -Danny
Unfortunately my prior experience with these things was based on a children's science book when I was in gradeschool. I still have it somewhere, but nobody's invented web-to-RL links yet, so you're probably better off asking Google.
However, I can tell you that the majority of the power comes from oxidizing aluminium. You can even replace the copper coil with carbon like is used in the heavy-duty type batteries and it will still work. So anything you can do to increase aluminium surface area will improve the amperage you can draw from it, as will anything you can do to increase the amount of oxygen it can absorb from the air (as long as you keep the electrolyte from evaporating, or replenish it.) Decreasing internal resistance by putting the anode as close to the cathode as possible will also increase the power.
The book I had suggested building batteries out of pennies, squares of paper, and squares of aluminium foil. Unfortunately pennies are no longer made of solid copper, and the zinc cores don't have the right electronegativity compared to aluminium, so if you do that nowdays you'll get a battery that works for about two minutes and then shuts down as the copper cladding on the coin corrodes in the salt water.
Be aware that the aluminium hydroxide produced as the battery runs down is caustic. So wear gloves when you go to disassemble and dispose of one of these if it's of any significant size.
Aluminium batteries like this are actually some of the most powerful known per unit weight if well constructed, and certainly the most powerful that are also stable. The only downside is that they are non-rechargeable without re-smelting the aluminium. But I have been tempted to see if I could build a set sufficient to run a model airplane since getting empty cans in large quantity is usually pretty easy. If I ever have time for that I'll post a video for you.
Holy cow Laurence! That is a very useful information filled comment! I have a bunch of cans I have been saving up so I might need to make two different versions one will a smaller diameter and more cells and one with aluminum can shavings inside of it. I am thinking about trying to carbonize a few #2 pencils, similar to the way char-cloth/charcoal is made. That should give me a carbon-graphite core to work with. From what I have found a graphite/aluminum cell gives about 1V amps would depend on surface area. What are your thoughts on that?
Don't bother with the pencils, it's not worth the time. Buy activated charcoal like is used in aquarium filters, or if you really want graphite, powdered graphite is available in bulk and relatively cheap.
What specific coil needed and the length per can
12 gauge copper wire. Use as many wraps as you like. I think I did about 5 wraps then stretched it to the height of the can.
Das wird viel interessanter ,vermuten

@ 6:42 when you're ✔ing 4 a a shortage, wht would/colud cause 1 ?
And how 2 fix it if possible??
Recharge it slowly a few times
It would likely be caused by the coil being in contact with the inside of the can, or in the case of wiring multiple together the way it is wired could cause it.

Could you tell what specific voltage of the flashlight head? Like the watts and others
Like what can be substituted to that if we can't find smth like that
Hi Wendell, most small white LED flashlight heads should work or if you have another type of LED from the front off an old junk computer tower. Usually the front power light or hard drive activity light.
You can use salt or some other kind of acid week acid maybe or strong I have not tested it

Good video. I can't really read the dial on your DMM but I suspect you're reading it wrong. 0.21 mA is awfully low for even one LED. I suspect it's 21 mA at least, and more likely to be 210 mA (0.21 A). Which makes your array a pretty good homemade battery.

Hello very nice videos your are making
Is there a possibility to make a video for making a really battery for use in photovoltaic (of grid situations)
With a very big capacity?
The dimensions and the weight it is not at all critical or problem there's on lot of space
Thank you very much for your time
Thank you for watching and commenting! I have plans to make some supercapacitors in the near future using things you have got at home. Most of the "DIY at home" battery projects would not have enough capacity for an off grid setup. From what I have seen high amp hours golf cart batteries would be most affordable which are lead acid batteries, and rechargeable unlike these batteries that are one time use.

What is the oxidation and reduction that happens in this homemade battery? I need the equation for my chemistry class, help me pls😭
Sorry I don't have the equation
For how long can you power a small light using these?
It ran for about a month. Also could you check out our newest DIY Power Bank from JUNK D Batteries project - ruclips.net/video/myTu52BbfiI/видео.html . Would love to hear your thoughts on it. I hope you're having a great day! Please give it a LIKE and SHARE!
Is it rechargeable?
Is it just a amateur project or can I use it as a battery?
Thanks for watching and commenting. It is not rechargeable. It is a primary battery, similar to an alkaline battery, that can be used for very small voltages and currents. Or you can use it to slowly charge a phone with the right adapter or step-up board.
There are two wires specified. Which is better to use? And where to buy pls send link thanks
The copper wired inside the battery is a 12 gauge standard electrical wire you can get at any hardware store. The smaller wire to connect the battery cells is I think a 24-26 gauge wire from inside and old broken HDMI cable that I had laying around. Gauge of the wire isn't important since it its very low voltage and low amperage.
does it really require play sand or just regular sand can be enough
Hi Mark, Thanks for the question. Regular sand should work I don't think the grit size would affect anything in the battery. I just used play sand because that is what I had. Please share and subscribe!
Awesome thanks. Does anyone know or tried an electromagnetic device in the middle of a bowl of salty water to see if it begins going 369 clockwise?
I have not, does it work?
@@SourcePortEntertainment haven't tried either. I get alot of ideas in my head in theory, especially when people like yourself share yourself. We can keep growing. I hope you try it 😁🤙
Good.
Thank you! Cheers!
