That transition after “come a little bit closer” 😂😂😂😂😂

3:13 this is such a genius cut!

Dude, that smash cut between him trying to woo that electron into him trying to generate a charge on that pvc KILLED ME.

The so-called “Baghdad battery” is believed to be from the Sassanian Era, roughly 224 - 651 AD. The jar was found in Khujut Rabu just outside Baghdad and is composed of a clay jar with a stopper made of asphalt. Sticking through the asphalt is an iron rod surrounded by a copper cylinder. The so-called “Baghdad battery” is not really a battery at all. We know this because it bears a very close resemblance to objects with an identifiable purpose found by a team of archaeologists from the University of Michigan in 1930 at the site of Seleukia, not far from Baghdad. The objects found at Seleukia look almost just like the so-called “Baghdad battery,” but we know they were, in fact, used to hold papyrus scrolls because they all contained remnants of papyrus scrolls when they were excavated. The scroll-holders from Seleukia consist of a metal rod that the scroll could be wrapped around and a tube inside a ceramic pot that the scroll to be slid inside for protection. Most likely, the so-called “Baghdad battery” is just a scroll container. The scroll was meant to be wrapped around the iron rod, slid inside the copper tube, and then slipped inside the ceramic container, which could then be sealed to protect the scroll inside. The acidic residue on the inside of the container most likely comes from the papyrus or parchment of the scroll that the pot once contained, since papyrus and parchment are both slightly acidic. Eventually, the scroll decomposed, leaving the acidic residue behind.

"Come a little bit closer" *HARD CUT TO PVC PIPE ACTION*

6:42 I would have never guessed that that would be the voice that would come out of that person.

“I’m 100% sure I don’t know what it was for.” Basically me when somebody asks me about cars

I used to watch your skits and stuff way back whenever. Since then I've graduated college. I know all this stuff from studying physics but man the way you explain stuff is really cool. I bet these videos really help people learn a subject that most find confusing and complicated to the point of giving up, and that's great. Thank you for what you do, I will now binge your videos.

3:12 is the greatest cut I've seen in youtube history. Nearly killed me laughing.

This "battery" is so useless he didn't even find a way to shock himself.

4:02 this is one of the best presentation of an electrolytic process I've ever seen. I liked that.

3:11 can we just take a moment to appreciate this transition

You're gonna be SOOOO embarrassed when they find that ancient multimeter.

Its an artifact from 2000 years ago and he STILL manages to find a way to shock himself.

3:12 "come a little bit closer" *shows mehdi scrubbing pipe viciously* 💀💀💀

3:11 i refuse to believe that the transition wasn't intentional XD

"This might seem like a good argument but it is actually a stupid argument." Damn, can't argue with that.

6:23. So all I need to do is put 24 giant Bagdad Batteries in series and repeat 1000 times in parallel and I don't need to buy a new car battery. Cool.

I watched Mehdi last weekend for the first time. His basics videos are great! I love his sense of humor. Just great! Thanks Mehdi!

3:14 hands down the funniest cut I seen in my life 😂

6:45 I gotta be honest, I would never have expected him to sound like that in a million years

I actually have fun learning from you! Keep it up!

Where was this man when I was in high school!! I would have LOVED to have him as my science teacher!

3:14 Holy shit did not expect that😂😂😂

Rubbing his rod on KZfaq after making flirty noises.

6:34 He is Holding 3v Coin Cell To Power Up Led!!😶😶

That transition was legendary 🙌👌👏

Definitely a battery cell for their spaceships.

Who cares about an ancient battery, the question at hand is: did they know about the FULL BRIDGE RECTIFIER?!?!?!

Just brilliant, no messing about, straight to the point and hilarious with it

I just found this channel, and Sir, I like your channel. You’re funny, charismatic, and teach in a way that everyone can understand.

that “no” at around 7:09 is now the transition slide to all my nightmares

"How about you come a little bit closer?" Segues to rubbing shaft vigorously Should we take it that you were not successful in attracting the electron?

When it jumped scenes and he was rubbing the pvc pipe? I nearly died 😂🤣

Thanks btw on this video and others, im doing my master's right now and im learning about Lithium ion batteries and thought about seeing your videos to get a glimpse of what i can learn. Thanks again

4:58 lol I love that infographic

Man flirts with charges & rubs his pipe while arguing about ancient batteries.

First time in a while I didn’t skip your little commercial like other KZfaqrs you funny as hell bruh

You're one of my favorite and most entertaining KZfaqrs. I like to download information from the interwebs into my brain, and you have good data transfer speeds.

So, to conclude: The Tower of Babylon was a giant battery that powered Atlantis.

3:10 i love how after he talks to mrs negi, he starts stroking his rod

this video is a complete masterpiece, from start to end, my favorite youtube video ever, and i am here since 2010 watching a lot of different stuff. This iranian guyis a legend

I'm from Baghdad, greetings to you

1:34 when your friend says "120 volts of current"

The batteries were used to charge up the alien ships duh.

Sir you are amazing, brilliant and best teacher.

That transistion to him cleaning the pipe was fucking hilarious.

3:10 *After he done talking with mrs negi he starts stroking his rod*

Mehdi is a(n): Electrical Engineer Absolute Genius who “Safely” Shocks Himself Comedian Super Electric Man DA REKTIFIYAH (many people said this) ALL. IN. ONE.

3:17 is the best laugh I had since a year 😂❤

I always find your calm zen like demeanor on the videos soothing 😄😄😄

"See, the battery actually is useful" said the guy arranging a room full of oversized heavily modified versions in series and using them to barely light a single LED.

4:05 Simplest (not to mention most entertaining) explanation of how a battery works that I've ever seen.

It’s good to point out copper tubes were used in abrasive cutting of holes in various materials. Maybe cutting holes in clay pots to store vinegar in, if there is any relation to the artifacts at all

I... wanted so bad for someone to explain how batteries work at school. All my physics teachers would say "a source of electricity such as a battery" and no one was actually able to explain the "how" of a battery... The skit did wonders for me to understand this. Thank you!

"I want to make you mine" Then pan to him stroking his pipe...LMAO..!!!

4:58 Oi, anyone wants an extra electron? Me me! Boop

That transition after the "come a bit closer", day was made XD

This man makes the best advertisements I have ever seen on KZfaq!

If only these ancient people had a Keysight Oscilloscope.

3:08 - This part had me laughing really hard XD I don't know if it was accidental or not. Especially that you are using a pink towel :P

I once read somewhere that hte "batteries" could have been multipurpose containers, for containing fluids for paintings, or fermenting fluids, of course the biggest down side is that, these artifacts gone missing during a war.

This has to be the best commercial for anything ever! It had thought provoking ideas :)

Okay, this was a solid take on the Baghdad battery i've not seen before. Also, your argument that perhaps the metals were placed in the wine to add flavor or healing properties....is not crazy. Copper, at the time, was known as "fire metal" and had symbolic importance.

"I'm 100% sure I don't know what it was for."

3:14 oh look hes pumpin one out lmao 😂

I don’t know why but haven’t seen your channel for a while it’s good to catch up with you again… great video.

3:08 meme material

No, we'd like to hear about ancient Tehran Turbines under the waterfall.

Hey there, Archaeology/anthropology graduate student here that specializes in South Asia and adjacent areas, including the Middle East. I just wanted to say that this is an excellent refutation of the notion that this was some kind of battery. Also, both of your proposed uses are entirely plausible. I’m not sure if this is the case in Iran, but in South Asia, there is an ancient medical tradition that includes the belief that copper includes properties that are good for the body. In 2021, there are even stores with special copper vessels that are specifically made so that you keep water in them and it gets that metallic “coppery” taste. Since this practice is also mentioned in texts dating back 2000+ years, it is very possible that Iran had a similar beliefs around that time too. So your random guess is actually seriously plausible, especially considering the relatedness of South Asian and Iranian cultures and the vast information exchange networks across Southern Eurasia at the time. Also, the stuff that ancient people in Southern Eurasia were actually making was cool enough for us to not have to make shit up. They were experimenting with clays, minerals and metals to make new types of synthetic objects (mostly for making things like ornaments). Some of these were ceramics by engineering definitions (i.e. sintered composites), which means that they were able to achieve temperatures high enough to induce a phase change. Also, during the 2nd-1st millennia BCE they developed how to make glass. They were also processing raw materials to make glues and lots of other things. All of this is many orders of magnitude more impressive than a bunch of useless pot batteries put in series to barely light an LED. Of course all of our tech is more impressive now, we have 2000+ years of accumulated knowledge and 7 billion people that can dedicate their entire existence to working out tiny problems in science. Thanks for the awesome vids!

@ 9:16 "BAGHDAD BATTERY JUICE" 'Taste like BALLS!!!' this killed me

This guy is one of the best teachers I have ever seen.

Alternate title: "Iranian man roasts an ancient Iraqi invention for 10 minutes straight."

7:02 "This might seem like a good argument but really its a stupid argument" Wow dude just destroyed everyone with facts and logic

Rubbing that rod was epic 😂🤣

I'd be okay with drinking "booger-flavored" tea if it meant it would cure cancer and world hunger, I don't know.

I lost my shit at 3:08 to 3:13 omg that transition was awesome 😂😂😂

As a Baghdad born myself, I really appreciate you saying "Baghdad" the middle eastern way.

Electro boom we need you regularly!

3:11 i refuse to believe that transition was unintentional 😂😂

3:12 that transition absolutely killed me!! XD

This is brilliant thanks for giving me a laugh before I go to work 👍

I remember on MythBusters that they found out the battery could be used for electroplating. They then noted that the artifact in the form they were found was actually missing the terminal and couldn't work if it was in the form it was found. They then speculated the terminals were lost before the battery got buried and preserved. I'm quite sure that's not how it works, but to be fair to them, they specialized in special effects, engineering, and science, not archeology.

great! he uploaded again! 3:13 was good tho

That Mohan guy sounds like an Asian Christopher walken

3:10 i love the hidden inuendo there

This is so funny and not what I expected to find. Thank you lol

What my teacher spent two years explaining, you did in 10 minutes 👏

3:14 You all thinking what i'm thinking? That's right. Science stuff.

Holy crap, I just realized I never actually knew how the chemistry of a battery works. Doh . . Thanks Mehdi!

Funny :) Thank you for the explanation of battery chemistry. It's a "start here" video on that subject for me :)

3:12 I'm dead laughing 😂😂

i wish you were one of my teachers at engineering school!

One of the funniest and most informative video I've ever seen

"Tastes like BALLS!" I died man! I freaking died. Thanks for killing me today!

5:00 if my teachers would have explained me like this then I could have never missed my class😂😂😂

Those 1.5k dislikers are those youtubers who make videos showing ancient people make battery 😂😂😂😂

That creative ad placement got me to click that Link! Damn!😲

“Negative electron momma”, LOL.

I'm making that "no" my miss hitsound on osu
