As a cuban engineer I could tell you that here in Cuba almost no private home has proper grounding. But In State properties the grounding standards are very well executed as you showed in the video. Thankyou for visiting Cuba. I hope you had a wonderfull time around here.
When you dont have food its is difficulty to care about proper grounding.
@@mvf1998You can't get any stupider than that
Cuba was good while it lasted. Politics killed part of the culture we'll never experience again.

Turning a trip to Cuba into a business write-off.
Well played sir.
Actually probly can write off very little...since the main purpose is vacation...if he just went on his own without his family probly could write it all off ...have to be extra careful with write offs ..probly could write off maybe 20% of his cost none of the familys ...any CZcamsrs would try to write off 100% of a trip like this woukd end up in big legal trouble at some point... especially if you are writing off multiple trips a year
Your family's reaction is honestly the most entertaining parts of these videos.
I'm surprised you're not on some kind of international hotel watchlist yet.
He is most likely that's why he had to go to Cuba 😂
Oh he is. You didn't hear it from me. I'm 'just a front desk clerk'.
Your going to start seeing pictures of his eye brow in hotels by you before you know it
I'd like to invite him at my home, I once recorded 100v between my desktop's case and a wet towel I put on the ground for measurement. He'd then run to look at the differential in the fuse box.
I'm more wondering if he actually got ban from a place? But yet again they didn't give him a rule to know, cause they never met him. Lol XD
Mehdi's family packing checklist: Pants, tops, underpants, socks, sunscreen, toothbrush, maps and visitors guides.
Mehdi's packing checklist: Keysight multimeter, probes, resistors, potentiometers, alligator clips, AC lead with exposed wires and an LTT screwdriver.
i bet TSA loves him
So you're telling me you don't carry resistors with you when travelling abroad?

@@vyladence I don't think Canada has "TSA" the same way that we do here in America...
@@fluke196c no it’s not !😡😡😡😡😡😡
Hi, I'm cuban and since I started watching your videos I always wanted you to come "check" our electrical system, but thought it'd never happen! THANK YOU SO MUCH!!!!
As someone who is Cuban, everything you experienced there is the most Cuban thing you can experience
Most people travel to Cuba for the beaches, the piña coladas, the rum, the cigars.... Mehdi goes to test the power installation in the room to consider it a satisfying experience. Same as all trips. It's inspirational, because you shouldn't let anyone tell you what to do.
Mehdi goes for a breaker trips hahahaha
I would go there just to buy a car and import it back to the US.
So many different trips in Cuba 😅
@@TestECull Good luck with that. Under Cuban law, those are intangible cultural heritage that are prohibited from being sold and distributed overseas...
I go to see the marvels of communism
YES I did watch a man test foreign electrical sockets for 22 minutes, AND IT WAS A DAMN GOOD TIME!!
Hahaha I thought the same!
11:01
For real, I hope he does more of these
i just realized it was 22min i thought 5-6min, time really flies.
And?
You know this is a guy who is vastly underappreciated. He looks like a dipstick who just shorts things out and goes "argh" but hes really an exceptional creator, his videos are immaculate, his knowledge of electronics FAR surpasses what he presents on his channel, the way he builds his videos and curates what he does, its fecking magical, its mesmerising. Honestly there arent many people on earth who can do what he does, bravo sir!
Yes He plays a naive learner to help you ask questions along the way. Fantastic creator.
This dude is an electrical genius and also financial. He does all this crazy stuff on vacation and records in the room, beaches, places he goes so he can write them all of as a business expense for content. GENIUS
I bet Linus never thought about his screwdriver ever ending up in Cuba
let alone being used by a random Cuban electrician
why though? They are a canadian company that ships worldwide and they made a really good product for repairing things...
Or Linus used Mehdi to get around the embargo and smuggle them in. IT WAS ARRANGED! ;)
@@RFLCPTR If Linus used a U.S. company for any part of it then it is subject to the US Trade Embargo with Cuba.
@@emmettturner9452 Well, yes, of course
This story of Mehdi gifting his screwdriver to the technician reminds of a story that my father told. He once had been on holiday in Cuba and the air conditioning failed. The technician had no phase tester, he had to test by touching the wires by hand. So my father gifted him his phase tester which he carried with him.
Not sure if Mehdi brought his standard ltt screwdriver but he was also gifted a special Creator edition, with a custom colour instead of orange. If he gifted the creator screwdriver then that was mighty big of him!
Getting a free tool is actually a much bigger blessing than that. Given Cuba's... state, tools and parts are hard to come by (especially for places not in Havana) so getting a tool is oftentimes something to celebrate... or exchange it with money (preferably foreign currency) to buy something nice.
Point is, some Cuban had a happy day that time...
@@theotherohlourdespadua1131 What *is* happening in Cuba really? We hardly ever see pictures like these on the regular networks, and you never see a Cuban location movie. Plus, the official version is always anti-Cuba.
@@Nehmo the USA won't trade with Cuba which means it can only have tools if it makes them itself.
Why? Because the USA is super pissed that 50 years ago Cuba decided not to give all its money to shareholders. That's why.
I see a bunch of European looking parts which is no surprise because they CAN trade with Europe. The panel looks European, also with the separate GFCI. The smoke detector looks like ones I've seen in Europe
The "its 12pm at night stop it" is very relatable
The fact he was doing that while his family was trying to sleep made me laugh sooo hard 😂
Power outlets: **peacefully hanging out on the wall**
Mehdi: *Do your breaker pop? Let's test it out!*
*Mehdi's Wife and Daughter from the other room while they charge a phone, camera, or try to dry their hair: * "Mehdi! Dad!"* Slippers being thrown while Mehdi hobbles to the electrical panel.
Yea power sockets hanging from the wall with exposed wires just sat there chilling out. Unless he touches them with his finger or meter probes and then a flash with magic smoke.
This man has discovered he can finance his family vacations by taking apart the outlets in his hotel on video.
God bless you man. I'm here for it. I'm just jealous I didn't think of it first
Also lets him right off the trip as a business expense for tax reasons. His genius is overwhelming

Something that I found really interesting when visiting, is that they actually hold an annual Terry Fox run, in fact they hold the second largest one every year behind Canada's. Canada's and Cuba's history together is so strange, but resulted in a really awesome friendship
So why you don't live there, outside the tourist areas?
I always wonder why Cuban men dress womenly, small shorts, tatoos everywhere, dyed hair and earrings.

I swear, Mehdi seems to be on a mission to pop every breaker in every existing country around the world
Or at least, one breaker per country
Hey look buddy, I’m an engineer that means i solve problems.
Not problems like what is beauty, cause that would fall within the purview of your conundrums of philosophy.
...at the same time.
One of these days he's going to find a faulty breaker and end up causing an electrical fire.
Eventually, he’ll be granted permission to visit North Korea hotel.
If I took a trip to Cuba, I'd ride in as many old cars as I could afford. It's nice that you're checking out so many electrical systems. Thanks for another entertaining video, Amigo.
Medhi,I want to give you a great thanks. I am from India.I am now 14 ,I started watching your videos like four years ago and now I had been started to known as an inventor in my school.
Its never a mehdi video without him causing blackouts or him just shocking himself 😂😂😂
I got nervous when he was driving past the power plant, thinking he was going to sneak in and try to pop a 20KV breaker.
"causing blackouts"
You need to look up what a blackout is.

2:16 The smoke detector in your room is an addressable/conventional smoke detector that is hardwired to a dedicated fire alarm system protecting the building. The beige colored one you showed in the same section of the video is, I believe, a smoke ALARM. Layman's difference: the smoke alarm will sound in its unit, though only someone calling the FD will actually initiate a response. A smoke DETECTOR wired to a fire alarm system that is monitored by a central station WILL have the FD roll the trucks on you as well as actuate the building's notification appliance circuit devices (the loud, strobing or buzzy red things we all hate).
Source: US Fire Alarm Techie +4 years
What happens if the smoke alarm triggers when there isn't actually a fire though? Even the best smoke alarms in the world can trigger in some harmless scenarios.
Mehdi, connecting the sink directly through the ammeter is insanely dangerous. Rooms are laid out mirror image to reduce pipes and utilities, so on the other side of that wall is another bathroom. There's a very good chance you just briefly electrified the faucet/shower in someone else's hotel room.
Very good point...
Bet that was quite shocking for the person taking a shower next door
Wow, so did we pass the test? 😅. Very impressed that you came to Cuba. I'm electrical engineer and we are familiarised with the bigs economical problems that we suffer, but they are a lot of technicians and specialist that try to do their work as better as the situation let's them. So happy that you been able to see the two parts of Cuba, the one we show to the turism and the other. I'm fan of the way you have to show and demonstrate the concepts, very very practical and fun. Congratulations
It's awesome to hear that you take such pride in your work even if it's made difficult by circumstances outside your control.

Glad to see you and the family having a good time.
After the collapse of soviet union, Cuba was left behind without any international help.
To try to fix the problem the government issued the book "con nuestro propio esfuerzo" (with our own effort) which contains a lot of tips and tricks to DIY fix, repurpose, build, and modify things, some of these devices are explained in a ElectroBOOM way! 🙂
This book is now available in PDF for free and is quite fun to read.
But still in Cuban Spanish...
@@theotherohlourdespadua1131well, Cuba is a Spanish speaking country so :/
@@theotherohlourdespadua1131 And in this low-tech state of humanity we're currently existing in, I can't think of 1 possible way to translate it.
Give up, it's hopeless.
Hello, I loved your video, I am Cuban and I am still currently living on the island, I hope you have been comfortable, a small explanation about the lack of ground connection is that most houses in Cuba do not use it since it saves in the cable, hahaha, it's more for reasons of saving money than for anything else, it's good that you were able to do tests since here they cut off the electricity quite often, but of course they don't affect the tourist. All the best
If only import fuel would be more available...
I wonder if Cuba would get nuclear powerplants, how would US react to it? I mean, they didn’t invade North Korea yet so I guess it would be lots of pundits screaming about it then everyone would just move on.
Do you have problems using devices with metal bodies when there's no earth protection? I was working on a house in France with no cables back to earth and got a nice, warm buzz off a fan trying to circulate air
Saludos, un venezolano aquí, se lo que es que te quiten la luz. Venezuela está también afectada en muchos lugares en ese aspecto. Mis mejores deseos para ustedes y que pronto mejore la situación tanto para Cuba como para Venezuela 😊
@@RyO-lt1ui it is a safety feature. Missing ground doesn't usually shock anyone but it means you are not protected against things getting broken and causing shocks
@@gabrielpadron5619 It will not improve as long as the USA is in charge. Both Venezuela and Cuba said they would not give all their money to the USA, and the USA is punishing them for giving all of it. Like a school bully.
Nice! I'm glad u visit my country, I hope you had a good experience here 🙌🏻
In Greece we have basically the same thing, some areas where it is hard to get a good grounding work without grounding. Also we have those 230-110 dryer sockets in tourist buildings and all outdoor lights are on a transformer and usually down the power to 12-42v. This sometimes they don't do this and it causes countless problems in winter
9:45 I always fully expect this to happen, but this time it made me jump off my chair anyway
Yes ,same here also 😂
11:00 I was expecting this too 😂
Fr
Normal tourist:
Let's pop open a 12 pack of beer and then see if there's a shortcut to the pool.
Mehdi:
Let's see if we pop a breaker if there's a 12k ohm short to ground. 😂
12 kOhm short? Thats resistance, not short. A short circuit is ideally zero Ohms, milliohms in real life.
@@mernokallat645 Maybe if you take your shirt off?
@@mernokallat645 Well in this case we usually see it as a "short" because the current is taking an unplanned path which could be destructive or dangerous, even though the resistance is much higher than what would normally be thought of as a short.
Why not both? Should be fun.
@@HeyChickens Thats called leakage or ground fault, not short.
Thank God your alive ❤
Saw your reels on Instagram which posted until 2020.
7:30 him setting it to amps and saying I will measure voltage sent shivers down my spine
I have two questions:
Do you take electrical components with you every vacation?
What do you tell the technicians you were doing when they have to come flip the breaker switch outside of the room? And how do they react? 😂
If one of those hotel owners recognise him he will get kicked out of the hotel or he would be forced to repair all the electrical systems 😂
Well it would be easy enough to pass off blowing the breaker by being a dumb tourist that plugged something in the wrong outlet.
And yes he does
Depending on the video, he just goes and flips the breaker back himself
I think he buys the electrical components from a local electric shop.
@@typicalmooyt69 Definitely not in Cuba
Just woke up and opened CZcams…and what do i see??

Great video Mehti. Thanks
Seeing Mrs Boom and electrocute hanging out in the background of these is so wholesome:)
(I'm making additional comments after the video went live to boost engagement)
0:55
That phone blew itself up to escape a coming danger
Is that a thermostat
I think it's not a phone
I'm fairly certain the outlets in the first place are Legrand. Very good. That whole installation is probably identical to what you'd see all over Europe. The technician deserves the linus screwdriver for sure.
8:32 This is very common. I have several of these inverted sockets at home, in fact, this video just reminded me that it's time to "fix" them, so I'll do it right now.
Didja fix them?
0:30 even the outlet looks terrified when Mehdi comes in
Wow same time
"😟"
Kind da sus🌚🌚
The smoke detector at 2:20 is not a household smoke alarm, like the one in the other hotel. It’s actually a modern addressable device, which is designed to be wired to a main panel in the middle of the building, and has a code set that will help the staff identify the location of the smoke.
I know it seems overkill for a hotel, but if you burn something, completely separate alarms will sound in every room, strobes flash in the halls, the fire department will be called automatically, AND the staff will know exactly which smoke detector activated, so they’ll know it was you, and the worst part, there’s no way to shut it off without a key and passcode, and in some places, it’s illegal for the staff to even do so without authorization from the fire department.
So in other words, don’t do anything that causes smoke, or even shower with the door open, because it can’t tell steam, or even dust, from smoke.
For anyone into fire alarm tech, it’s a Notifier by Honeywell 851 series smoke sensor.
I hate these things, I went to a hotel that had these and told me to be careful, but I guess it‘s better than no smoke detector or a broken one.
Totally love you're videos. Keep them coming
“I see traces of some excitement here, was I here before?” Never change Mehdi, never change 😂
I love that the preroll ad on one of his video was for katko safe connectors where they hung a car from a crane
His addiction to popping breakers is growing, taking his family on vacation under the guise of holidays. Well played Mehdi
The only guy to bring a multimeter and test hotel outlets. Love this guy
The hostel wiring reminds me of the ancient wiring from upstairs in the apartments in the funeral home I briefly worked at, where they space the wires from stud to stud and have no insulation in the walls.
my favorite series
I love how this video went from more of an electrical testing video to a vlog type video with the family, I wish they were in here more
Can't describe how much I love this series. Cuba is gorgeous. Love how many classic cars are still running and in great shape, too!
It's necessity because the USA government is bullying them
The cars are nice but the reason for them is not nice, the US bans any country from trading with the US if they trade with Cuba and of course Americans have more money so no car company is willing to sell to Cuba and then get banned from selling to the US. Cubans just repair the cars they already have. (Notice the message written on the bus at the end of the video.)
@@amihart9269 The US is the villain in the world.
@@amihart9269 Lol Cuba government buy new cars without a problem from Korean, Chinese, European, etc. The entire Police fleet is Peugeot. Regular cuban don't have new cars because for a long time government prohibit their people from owning private cars, so only cars before the 1959 Revolution were allowed to be buy and sold in the private market. Today after some reforms Cuban can buy and own private cars but they are out of any regular people salary.
@@amihart9269 re: "the US bans any"
But - other countries? France? ENgland? Spain? Italy? Mexico? Huh?
Mehdi, you walked trough my childhood neighborhood, ohh men, you just bring me joy. Thank you for traveling to my beautiful island.
i love how this dude just records like 10 mins of his vacations and probably writes them off as business expenses
These videos are so interesting. That kind of "spare parts and improvisation" situation seems pretty prevalent there -- doctors, mechanics, electricians, all kinds of professionals who don't have ready access to the latest gizmos, so they use their brains and what they can find, and they do the best they can. It must be a big challenge, and it's really great that people rise to it.
11:47 Mehdi just gave his one of a kind creator (= special color) screwdriver away. 😭 At least I hope it found a place in a loving new toolbox.
"I see some traces of excitement. Was I here before?" Thanks for the chuckle. : )
Rewatching these - great channel
As someone from Brazil, I have seen many places like that, and I can guarantee that the lack of ground and those inverted pins are not due to technology or safety... Most electricians just ignore those because of the infrastructure or costs. It's usual to get shocks from the shower or fridges here. Those breakers are a luxury most houses don't have (I've only seen them in new buildings).
In most countries neutral wire is grounded on the power plants and transformer stations. I guess it helps to level out potential between different parts of network, but also this is what makes live wire, well, live. Mehdi found out at tha second place that not only outlets lack ground connection, but also have floating neutral. And probably it was intentional, to make it safer.
@@voidseeker4394 It's grounded to make sure that plugged in household appliances that requires ground (because of metal encasing for example) are also grounded and do not shock you when somehwere in the system a short between the ground wire and a live wire happens or a lightning strike hits it.
Yea, it's safer when you touch the live wire but grounding itself is a safety measure for cases where you don't touch the live wire directly.
@@Bobylein1337 uhm, i don't understand what you're talking about. Neutral wire, by definition, is a grounded wire used to get reference potential. If neither of wires is grounded, there is no live wire, both are equal. And shorting it to ground won't do much, because it's whats already done in most countries. And chassis ground is different from the neutral wire, it's dedicated wire, usually grounded locally near the building.
@G E T R E K T your example is irrelevant, 12v battery terminals have potential difference with each other, obviously. But there won't be any noticable current flowing if you connect one of them to the ground. Also, battery outputs DC, while power grid runs on AC, which makes wires change their potentials at 50/60 Hz frequency.
@G E T R E K T i know that ungrounded circuit can have potential difference to ground, but resistance is so high it won't allow any significant current flowing to ground. This is exactly what Mehdi shown in the video. Voltmeter is reading voltage between floating wire and ground, but it doesn't provide current flow.
11:04 that’s why I hear other roommates movin the furniture when I’m on vacation
I love the old cars in cuba. Big fan :)
I’ve been following you for years and always love your content! Cant afford to buy anything but i give my likes and always watch
22 minutes went by in a flash.
I wish it was longer. Cuba is truly a gem.
Consider doing a video about ground and floating ground.
mehdi needs to go on a cruise ship and test their electrical systems 🤣
I agree.
I'd pay good money to see another video like this
Very funny and interesting trip. Amazing how electricity is different around the world. Oh and ty for the vacation. Ill never go to Cuba or Hawaii but with your family i did cool thanks again. Keep them videos coming.👍👍👍
I find it fascinating that the electrical outlets in Cuba reflect the country's rich history. Pre-revolution it was essentially (or until 1902 literally) an American colony sharing their familiar outlets and 110-120V supply. Post revolution, 220-240V was appealing for compatibility with the USSR's influence. In the 90s forward (the USSR's collapse and Cuba's Special Period) it's been a mix of influences from China (as investors and tourists) at 220V, Canada (mostly as tourists, but who unlike the US have maintained standard trade relations) at 120V, and various other influences. This all lead to different buildings in Havana, or as you found even the same room, having different voltages. There truly is no engineering without politics. Things tend to not work perfectly (like the reversed outlet you found) but I find that all the more charming.
There's a nuclear power plant which was never turned on just outside of Cienfuegos (a really lovely city in its own right) that I'd love to see someone report on (though this would definitely require some government involvement which is... complicated).
Loved this video Mehdi. I can't agree enough that the Cuban people are incredible: kind, resourceful, and clever. I hope you, me, and others get the chance to visit again.
You should come to Norway and test our CBs, also look at our two different earthing systems! Love all the vids❤️
This videos is like vlogs with outlet testinf. I love it
16:45 switch is off😂
your wife sounds super fun that giggle at 9:54 was hilarious 😂 😂
It could be his daughter
She says baba. Prob his daughter.
9:51 She sounds steamed

Nice car at the beginning love those older style cars
Causing electrical Cuban chaos, and gets to drive around in a Barbie car.
Hotels that cater to international tourism often have those "universal" outlets that accept a wild assortment of plugs. It usually isn't the socket that is usual in residentual buildings. What I found interesting is your video is that your hostel had two different voltage conduits installed
4:29 Yeah, I could see him grabbing a random tourist to see if an electrical outlet is safe.
Cuba is beautiful I love the architecture and the cars
I love how he touches something and feels pain and then proceeds to touch it again
Wow Cuba is beautiful, I wonder what it would be like without a decades long embargo.
Part of its look is primarily due to a near total economic collapse after the fall of the USSR. Cuba pre 1992 isn't like that: thry used to have heavy industry and industrial agriculture rivalling that of the US in terms of mechanization... all powered by free oil from the Soviets. After the collapse of the USSR and the sucessor government saying no more free oil for Cuba, everything collapsed. Cuba in the present is barely holding by...
@@theotherohlourdespadua1131 So the collapse of one of the few countries in the world both willing to ignore the embargo and able to provide material aid to an ally had a negative impact? Cuba's real problem started in '62 not '92 with the yet to succeed embargo imposed by the USA.
@@Kalossabrakstein the US is getting weaker, and Cuba's friends are getting more powerful. The only countries at the UN that don't condemn the blockade are the USA, Ukraine & Israel. Some day soon the pressure will be relieved.
@@Kalossabrakstein I don't know if I agree. There are undoubtedly issues of corruption within Cuba's leadership, but Diaz-Canel and others are clearly interested in pursuing the modern examples of socialist models. Their close allies in places like Vietnam have been able to provide material wealth for their citizens, while maintaining political autonomy from the West because of geographic isolation. Cuba on the other hand has nearly worldwide political solidarity for it's independence from the USA.
2:21 Those are commercial smoke detectors that are tied directly to the buildings Fire Alarm Control Panel (FACP). Setting it off will set the entire building into alarm, if it's set up as an alarm and not a supervisory. It may just set off three floors; The floor of alarm, and one floor above and below. If it is set up as a supervisory, it will just let the hotel staff know to check the room.
The smoke alarm in your previous video can either be standalone or tied into the building FACP. The difference is it's an older conventional device that is wired in zones with other devices so staff won't know exactly where the alarm is coming from, typically just the floor. The one in this hotel is addressable and (If programmed correctly) will tell the staff exactly what room it is in.
A month ago I didn't know anything about fire alarms, but my four year old has become obsessed for some reason, and constantly watches videos about them and knows all the brands and lingo. It is starting to rub off on me. He even had me install a mini xp95 loop with a C-TEC panel in his bedroom. Now I also constantly notice and ponder on fire alarms and call points etc wherever I go.
Are bedroom smoke detectors programmed differently than hallway smoke detectors? Like do they enable verification or set it up as a supervisory like you said? What’s typically done in most hotels and what not?
@@mattdude It depends on the AHJ (Authority Having Jurisdiction, typically the fire marshal) and the fire code in the country/state. Some have all hotel rooms report as just a supervisory with local sounders, sometimes it's a fire alarm and sets off the entire building. The common area smokes will typically send an alarm.
Nice trip you had there, my Grandpa was born in a town south of Havana.
This is so sad. I am a Cuban and I left the country before I could go to any of those places, in fact I didn't even know they existed. However I hope you had a great time!!! love your videos
I just love that his family is supportive of his antics even when it comes at the the cost of awkwardness
Wish i had a family like that
The device labeled "diferencial" in the breaker box is a residual-current device, which acts like a GFCI through the whole circuit to which it is connected to (like you mentioned at 2:48). All standards based on the IEC 60364 use this RCD device, like we do here in Brazil.
Could you explain more about the isolated transformers? There's not a lot of videos about them and they're confusing
@Sayori Isolated transformers are usually at a scale of transformation of 1, but the secondary can be any voltage you want. The idea is that nothing is grounded on the secondary side. There is no reference to the ground. There is a voltage between the two ends of the secondary winding. If you short them to the ground, one at a time, nothing happens. You can safely touch them. (NEVER TOGETHER AT THE SAME TIME!!!)
@@RonaldoHoxha but that's one thing i don't get, if there's a voltage between the ends how doesn't it travel through your body to somewhere like the ground how.
Like lighting doesn't it travels through the air to the ground and anything between it
@Sayori the circuit needs to be closed for the current to pass through. If you ground one, no current flows as the path is not completed to the other side. BUT in some rare cases, one side may be shorted to ground as a result of damaged wire insulation, so if you accidentally touch the other side it becomes dangerous because in this scenario the circuit is completed. One side of secondary - broken insulation,exposed wire touches grounded metal parts - you - other side of the secondary.
It is true there are some capacitive leaking but they are negligible at low voltage and not dangerous to humans.
Lightnings on the other side have enormous power and produce very high voltages, which at some point make air a good conductor.
@@RonaldoHoxha oh i get it now i saw a video that showed that exact situation where you close the circuit between the 2 isolated wires with the ground
Lovely that you bring in your people in your vids, speaks well of an "enlightened'' person, Salutations.
I just spent 20 minutes watching you test sockets in a hotel room. You should take that to heart 🤩
That man still manages to make me flinch. Ive watched so many videos from him i should know whats coming when he handles bare wires but i still jumped at 09:47
You know what, but not when.
I love how these videos are part international travel vlog part home inspection.
You're a treasure, Mehdi.
Hide your outlets, hide your breakers, this man is going to trip them all!
U are the best person in the world full of joy .. knowledge , humour and kindness....love your content ....
AT 11:29 Mehdi looks exactly like "Grumpy Cat." Glad you guys had a great time in Cuba and hope you are all well. And as always enjoy your mildly ridiculous content!
