So don't go thinking helicopter rotors are just powerful fans because there's much more to it than that!
I'm an aerospace engineer, who worked with helicopters. I second your comparison. All the rest is negligible especially for No Effort November. Also, the last fan, attached with the cord, perfectly shows why helicopters need a second rotor placed at the tail. Love it!!!
I also want to acknowledge how Alec has gotten skilled enough that the "no effort" videos are still better put together than some fancy ones (and most ads, which companies pay Real Money for).
i love that he's really putting in less effort for November. In Novembers past it felt like he was just saying he put in less effort while actually staying close to the same standard. THIS is the no effort November i always wanted
Fun fact! The thrust, movement, and changing weight of a ceiling fan makes it a live load. This is why ceiling receptacles have two ratings -- one for chandeliers and one for ceiling fans. For example, the ceiling boxes I just bought for a house remodel are rated for a 50-lb chandelier (dead load) OR a 35-lb ceiling fan (live load). Edit: I believe the ceiling fan-rated boxes have a different bolt pattern than ones that are only rated for a flush-mount light fixture, so it would be pretty hard to mount a ceiling fan to a receptacle not meant for one. (I have seen it, though, the fan was dangling by one screw.)
Mine are mounted on whatever was in the ceiling when the house was built. And I'm sure that was well before ceiling fans were a thing. So, they're not rated for anything. They've been there for 28 years or so without falling off.
Oh people will find a way to use the wrong receptacle. Never underestimate the ingenuity of idiots. With enough baling wire and duct tape, you can jury rig anything.
Yeah, and for those not familiar - the heavy duty ones have to mount to a joist, either directly or with a bracket that spans between two joists. A standard flush light fixture box is often just clamped to the ceiling drywall. You do not want a fan supported only by a couple little ears holding the drywall!
"Fan" is an exaggeration. These things are air stirrers. Also: I loved the "which is a different number in kg" snark. Especially since SI prefers to measur thrust in N.
I like to think that when Alec was shooting, he just did a bunch of takes of "which is a different number in kilograms," then shuffled them before the final render.
This is very useful because I will henceforth reference all jet engine power output in the unit of Ceiling Fans. The F35's P&W F135 afterburning turbofan produces 43,000 ceiling fans of thrust (on full AB).
The object on the table next to you being unreasonably massive is such a great recurring gag. This, the fridge, and the dishwasher video all got a good laugh out of me.
Don't forget about ground effect --- running a propeller near a surface will generate more thrust than in free air, because the pushed/pulled air can't get out of the way because the surface is there, increasing the pressure differential. It's what makes ekranoplans fly, and is also why it's hard to fly a drone near the ceiling (it keeps getting sucked up and hits it). I'm afraid you're going to have to do all these tests again, but with a fake ceiling present!
0:56 Fun fact, since most helicopters' tails are shorter than infinity feet (infinity meters), the tail rotor doesn't just produce a torque force, it also produces sideways thrust. Because of this, the main rotor is tilted slightly to the opposite side, to produce a counteracting thrust and keep the aircraft from drifting sideways when the controls are neutral.
@@kv4302 Math involving infinities is weird. The number of integers is aleph_0, which is also the number of rational numbers and several other things. The number of reals is aleph_1, which is infinitely larger than aleph_0. Multiplying infinities by finite numbers generally just gives you the same infinity you started with.
So I’m a certified scale technician, and I would love to offer some of my experience in this field to help setup experiments like these. I would suggest that instead of using a hanging scale maybe you can flip everything over and anchor the fan to a floor scale which will give you a more stable reading and I could provide an indicator that will zero out after placing a load on the load cells. If you use a 4x4 platform with a load cell in each corner and wired to a junction board and then the indicator the you got a sturdy base
A problem with that solution is that when you have a plaform below the fan, the air coming from the fan will push/pull on the platform it self, cancelling out a big part of the "thrust". But it would work if you replace the platform with a large frame instead (which is much larger than the fan diameter, so the air can pass thru unaffected), that has it's corners resting on the load cells. Then attach 2 thin wide beams to that frame, going thru the middle of it, with their flat sides vertically (so they "cut the air" with neglectable area perpendicular to the flow) at which the fan in turn is attached to. If the fan gets too close to the floor, the thrust may increase slightly though - due to a high/low pressure zone building up when the the in/outflow to the fan gets restricted - but the same thing will happen to a fan mounted close to the ceiling. It even happens to a helicopter very close to the ground (it get slightly more lift there compared to when it has gained some altitude). So that's more a question of what one wants to measure. But the load cells and corners on the frame can be placed on top of something, for example 4 stools to get a "free air" measurement, like he did here.
Is that figs on edge or figs laying flat ? Also this happens to go well with banana measuring. One fig laying flat is the same as one banana thickness 🤔
Those low speed high velocity style fans for industrial use are kinda terrifying but awesome to have. At an Autobody shop I was working at, it was built into a building that was initially used as a warehouse. We have ceilings that were around 35 feet high so they got these fans from the brand "big ass fans" each blade was probably about 12 feet long and a foot wide. They were massive and if you turned it up it went WORRYINGLY fast but boy did that thing move air. Whenever we were welding or applying blackout tapes or stickers to cars we'd have to lower the fans down to like 5 or 10% speed because if we didn't it would blow away the shielding gas and make the stickers flop around like you were working outside on a moderately windy day.
I've seen that brand before! They had them in some spots at Gardens by the Bay in Singapore. I thought the logo was funny. My God, did they make a difference in the blasted tropical climate.

Be careful to note that the US doesn't use Imperial, but rather US Customary units. Some units in Imperial definitely do not have the same value in US Customary.
@@busimagen The difference is mostly units of measure of volume, if I recall correctly. That and possibly units of length smaller than an inch, which no one actually uses in the normal course of events. The Imperial system is basically just 'every specialised unit of measure of things relevant to a specific field, standardized such that unit X is always unit X, with people then prefering to reuse existing units rather than create new ones if the existing units were sufficient to their new task'. Over time some fell out of use as the specialty they came from was less significant, and then sometimes things were rationalized a bit when that left gaps that became an issue later. Imperial units are Very Good at the things they're intended for, and Terrible at everything else, and conversions are a pain. US customary units Started Out as British Imperial units, but then things happened. SI units (kind of sort of metric but not exactly) are intended primarily for scientific applications, and for stuations where great precision is needed, as well as to minimise, simplify, and/or eliminate conversions wherever possible. Officially only the base units and multiplying or dividing it by 1000 are actually Things in SI, but you'd be hard pressedd to find a country that uses the metric system that doesn't add additional units for practical reasons: Centimetres (1/100th of a metre) are pretty much universal, for example. Some places use decilitres (1/10th of a litres), most places will use teaspoons (5ml), tablespoons (10 or 15ml depending on country), and cups (250ml, or 1/4th of a litre, or 200ml, or 1/5th of a litre, depending on where you're talking about... good odds on one of those having it's origin in American units and the other in British, though it's quite possibly unrelated, but it's very confusing when you end up with the wrong one!) for cooking because it's just substantially more practical for things of that scale for that particular application. ... and don't be surprised if you find the occasional stray imperial unit still floating around for certain niche applications.

Fascinating! On the topic of heat fans, there is a product that isn't sold anymore today, but was wonderful in it's time and should get a retrospective: bathroom heat fans. Heater/fan combos, mounted directly above the shower or bathtub, which have heating elements just like a plug-in heater and a fan to direct that hot air downwards. They were wonderful when they existed, as they were perfect at helping you stay warm while drying after a shower. I cannot find any of those for sale these days. Maybe it's because they needed a lot of power to produce that heat, and infrared lighting is much more efficient at the same thing. Or maybe it's because it used exposed heating elements in the bathroom, immediately above the thing with all the water, and that has some obvious safety concerns. It would be great to see an analysis of those, and a comparison to the modern alternatives.
A question for you, maybe for Conextras.... If you have two ceiling fans in the same room or space, should they both be spinning the same direction or opposite directions for best heating/cooling/air flow results? I have two ceiling fans in my living room and always wondered that. I was at the local hardware store and I noticed their fans were spinning both ways. I didn't know if that was on purpose or if the fan installer / maintenance guy was just lazy. This is a burning question only I am sure you could solve lol Love the vids my favorite UA-cam Channel!!
10:24 my takeaway is not that you put effort into every video but that your content still shows a lot more production value than 99% of youtube DESPITE the lack of effort AKA youre a natural
Being a fan of fans I have watched Dan’s videos since I was very young and could first access UA-cam. As of recent I’ve been supplying him with short videos of Australian ceiling fans.
Can't wait to see if you flip the little switch and test the generated force in both directions. Consistent data will make my inner scientist so happy. ⚖️
I can't wait until this turns into a viral back-and-forth between science UA-camrs who will say, "but you need to account for (proximity to the ceiling, proximity to the ground, ground effect, etc... I'm not a science)". Like the whole series about electricity between Smarter every day, Veritaseum, and Electroboom.
Ah, that happened eh? I've never watched electroboom, I stopped watching Veritasium over his smug wrongness, and I stopped watching Smarter Every Day over his kooky support for religious exploitation, disgusting family dynamics, and anti-science.
The complete lack of duct tape makes me wonder if this is truly a no effort November video. That aside, it was clearly easy to watch, so that it likely counts. 🎉

@@wadewilson524 Are you right? Yes, you are. However, given the above video says an airplane's propeller makes so much thrust that it makes an airplane fly, wings are beyond the scope of this comments section. Please, don't feel bad. Mass and gravity have been omitted too. ;-/
@@wargamingrefugee9065 An airplane's propeller is also an airfoil.... more akin to a wing than a simple fan blade. Don't feel bad, these things are sometimes hard to understand.
9:15 Absolutely blown away that modern technology can produce a high velocity AND low speed fan /j [unless that actually is what they are called, then my bad. but a quick google search showed only a bunch of high * volume * low speed fans]
I’m a big “fan” of this “fan”-tastic video! “Cool” to see a fellow fan enthusiast Dan and his wealth of knowledge on ceiling fans featured here. Can confirm myself that Envirofan Goldlines are among the best industrial ceiling fans one can buy :)
Oh and much love for the outtakes. It seriously is what makes me keep recommending your videos to people cause it shows how human even youtube super celebrities are
I've had to reinstall an old ceiling fan mount before because it was barely put up, and the torque from years of running was working it loose and causing a serious wobble. Amazing how someone could put up a fixture that will be holding a heavy object above people's heads and think a single nail will be enough.
Some cool and important trivia about propellers and helicopter rotors. Both of them are wings attached to a spinning shaft. Thanks to their angle of attack they will in fact generate thrust, but that thrust is nowhere near enough to make a helicopter fly or a plane to move forward. What makes their shaft move axially is the lift they generate. On the plane the lift is pointed forward, so the props "fly forward", and since the props are attached to the plane, the plane goes forward. On helicopters, the lift force goes up, and so does the helicopter. Technically, you could get lift with no thrust if your prop blade has a profile that generates lift with zero angle of attack. Ceiling fans (and any other fan, to be fair) are closer to modern jet engines. Actually, a turbo fan engine is a big fan blowing through a tube which its cross section area gets smaller and its powered by a jet engine. If you replace the engine core with an electric motor, the whole engine would work the same way.
Thanks for adding in the clarification of what makes propellers work. Isn't the zero angle of attack how stealth works, to minimize the impact that creates sound waves?
By the way about “jerk force”, in physics/mechanics jerk is the name of the variation of acceleration. If you derivate position over time you get velocity. If you derivate velocity over time you get acceleration. If you derivate acceleration over time, you get jerk! If you derivate jerk over time you get snap, variation of snap is crackle, and changes in crackle over time are called pop.
Umm actually, the fan does not get heavier or lighter due to its operation. The weight is the same but the rotation of the blades imparts a separate force which acts on the scale.
There was one a few years ago looking into why fans with rotary dial/knob controls almost always have the speeds in descending order (Off-High-Medium-Low) instead of ascending order. "Fans-High Is Next to Off on Purpose."
Most likely, your friend Dan is the world's _premier_ source of ceiling fan knowledge. But your captions said he was the _premiere_ source. I'm confused!
It's probably more worth being pedantic about the kilograms/newtons distinction. He says a "[x] kilogram reduction in *weight*", but kilograms are *mass*. It would be more correct to say "the thrust exerted was [z] pounds, or [y] newtons, which would feel like [x] kilograms in typical earth gravity". But because newtons aren't used in everyday situations, kilograms is a more human-centric and relatable unit.
8:44 I'd wanna wear a bullet proof West at least to go near that thing. Ceiling Fans in general are a touch scary due to their exposed blades and because we don't have them in europe, but "mounted" like that and beeing so unstable thats a wholy different thing
They're much less common in northern europe, but do exist, I have one in the UK, and my friend in France has one, my friends in Belgium, Poland and other countries have seen them, but dont have any. My friends from Portugal and Spain say they are common there though, although I'm not sure how frequent it is compared to the US where they seem ubiquitous.

Officially only the base units and multiplying or dividing it by 1000 are actually Things in SI, but you'd be hard pressedd to find a country that uses the metric system that doesn't add additional units for practical reasons: Centimetres (1/100th of a metre) are pretty much universal, for example. Some places use decilitres (1/10th of a litres), most places will use teaspoons (5ml), tablespoons (10 or 15ml depending on country), and cups (250ml, or 1/4th of a litre, or 200ml, or 1/5th of a litre, depending on where you're talking about... good odds on one of those having it's origin in American units and the other in British, though it's quite possibly unrelated, but it's very confusing when you end up with the wrong one!) for cooking because it's just substantially more practical for things of that scale for that particular application. ... and don't be surprised if you find the occasional stray imperial unit still floating around for certain niche applications.
Whatever video you'll end up releasing as close to April 1st as possible, you should use only old/obsolete units of measure. Barleycorns, karobs, jigs, fathoms, whatever fits the worst.
Sincerely,
A person with other units.
Through the magic of imploring via two different videos...
I implore you to release Technology Connections branded socks, with the tagline 'Through the magic of buying two of them'.
I love it.
Saw the last comment, seconding my like
I second this.
Again.
God damn it now I want a pair lmao I saw your first comment too lol
Thirding! So happy to see this comment again 😅
Fascinating! On the topic of heat fans, there is a product that isn't sold anymore today, but was wonderful in it's time and should get a retrospective: bathroom heat fans. Heater/fan combos, mounted directly above the shower or bathtub, which have heating elements just like a plug-in heater and a fan to direct that hot air downwards. They were wonderful when they existed, as they were perfect at helping you stay warm while drying after a shower.
I cannot find any of those for sale these days. Maybe it's because they needed a lot of power to produce that heat, and infrared lighting is much more efficient at the same thing. Or maybe it's because it used exposed heating elements in the bathroom, immediately above the thing with all the water, and that has some obvious safety concerns.
It would be great to see an analysis of those, and a comparison to the modern alternatives.
"Which is a different number in kilograms" gave me a much-needed LOL!
7:59 "I will probably make a video about this fan, specifically, one day..."
Four years later...
I never wasted money buying into those fancy ceiling fans! So glad I just ducktaped a Cessna 172 to my roof.
My man got his reuse down.
A question for you, maybe for Conextras.... If you have two ceiling fans in the same room or space, should they both be spinning the same direction or opposite directions for best heating/cooling/air flow results?
I have two ceiling fans in my living room and always wondered that. I was at the local hardware store and I noticed their fans were spinning both ways. I didn't know if that was on purpose or if the fan installer / maintenance guy was just lazy.
This is a burning question only I am sure you could solve lol
Love the vids my favorite UA-cam Channel!!
Hmm. My first thought is if they're spinning in the same direction they might cancel out where they meet creating a dead spot.
This is the kind of hard hitting journalism I didn't know I needed.
10:24 my takeaway is not that you put effort into every video but that your content still shows a lot more production value than 99% of youtube DESPITE the lack of effort
AKA youre a natural
Missed opportunity to say “Christmas time is going to be FANtastic”
Thinking up the pun would have been effort.
"Why didn't you convert to kilograms?" Because that would require effort.
Through the magic of dividing by two, we can see it in kilograms! 😉
Except for every time he converted things into grams. XD
1:49 Save big money at Menards 🎶

Glad to see you using no effort November to interact with your fans. Not all UA-camrs appreciate their fans.
[Insert OnlyFans joke here]
Haha
You said “insert” 😂😂😂😂😂😂😂
flat
You will feel blown away
Ba-dum tiss.
Ah, so it's actually Dan's Effort November!
I don't know about a ceiling fan by itself, but a ceiling fan attached to a microwave and a hamper can take a toaster to mars.
😮
"which is a different number in Kilograms" is my new favorite bit
Being a fan of fans I have watched Dan’s videos since I was very young and could first access UA-cam. As of recent I’ve been supplying him with short videos of Australian ceiling fans.
Fantastic! Now instead of going to the gym i just attach a ceiling fan underneath my legs. Never knew losing weight would be that easy!
This is something I unironically thought of many times, thanks for answering my unasked question! XD
Thank you for the effort involved here.
One wind turbine asks another;
"Do you like music?"
The other tubine says;
"Yeah, I'm a huge metal fan."
10:44 surely you mean the next video ought to be FANtastic?
Hey just fyi I don't pay for your patreon but was able to access this video from the link in the email notification from it since i follow you.
Heh, thanks! I think I forgot to redact the preview this time.
you snitch
You were the person at school who reminded the teacher they set homework aren't you? 😂
@@PaulTheFox1988 I'm not proud of who I've become 🥺
Can't wait for part two of this where you investigate the Jerk Force of your fans.
Can't wait to see if you flip the little switch and test the generated force in both directions. Consistent data will make my inner scientist so happy. ⚖️
Waiting for the DeviantOllam video about breaking into a building through the ceiling fan...
The fantastic fun fan facts were fantastic!
3:15 I appreciate the effort that was put into converting to not silly measurements for no effort November
There is a whole community of fan collectors out there with a wealth of knowledge. Dan is only one of the many.
Great video though.
I don't know what I was looking for when i opened a youtube tab, but Alex is here to deliver what i need.
Now we are asking the real questions
I can't wait until this turns into a viral back-and-forth between science UA-camrs who will say, "but you need to account for (proximity to the ceiling, proximity to the ground, ground effect, etc... I'm not a science)". Like the whole series about electricity between Smarter every day, Veritaseum, and Electroboom.
Action Lab will install one in an elevator in which a drone is flying
Smarter Everyday is probably still getting reaction videos about the mistakes in his gyroscopic precession in helicopters video
Mould will mount water bottles on it and challenge people to predict the shape of the water trails.
Vsauce enters the chat:
But what IS a fan?!
Ah, that happened eh?
I've never watched electroboom, I stopped watching Veritasium over his smug wrongness, and I stopped watching Smarter Every Day over his kooky support for religious exploitation, disgusting family dynamics, and anti-science.
I do appreciate how the level of effort has steadily gone down throughout the month, he's embracing it more every video!
No joke this is how the Brave Little Toaster goes to Mars in the film The Brave Little Toaster Goes to Mars.
I do think that the fans may produce more thrust when blowing upwards against a near ceiling from something akin to ground-effect.
The complete lack of duct tape makes me wonder if this is truly a no effort November video. That aside, it was clearly easy to watch, so that it likely counts. 🎉
Dan the fan man! Thank you! and thank you TC!
Can you try a builder's grade bathroom fan that does nothing but swizzle the air and collect dust?
Like an exhaust fan? Or something else
I have one of those! 😂
So right! Quite unlike my Electrolux, these bathroom fans move more dust than air.
I think they're supposed to suck stinky air and shower steam out of the room. Or do you mean specifically a crappy one that can't even do that properly?
@@stevethepocket a crappy one (no pun intended.) It just spins and doesn't draw the air out.
Gosh some people sure are gonna be a fan of this.
10:04 which November based event are we talking here?
The first ever no effort video to come out in november
Technically, a helicopter rotor is a “rotary wing” producing lift.
AKA a fan.
@@seigeengine No, its a rotary wing. There's a difference.
@@wadewilson524 Are you right? Yes, you are. However, given the above video says an airplane's propeller makes so much thrust that it makes an airplane fly, wings are beyond the scope of this comments section. Please, don't feel bad. Mass and gravity have been omitted too. ;-/
@@wargamingrefugee9065 An airplane's propeller is also an airfoil.... more akin to a wing than a simple fan blade. Don't feel bad, these things are sometimes hard to understand.
@@wadewilson524 And on my fan, the blades ARE airfoils, so there's that... =)
9:15 Absolutely blown away that modern technology can produce a high velocity AND low speed fan /j
[unless that actually is what they are called, then my bad. but a quick google search showed only a bunch of high * volume * low speed fans]
I’m a big “fan” of this “fan”-tastic video! “Cool” to see a fellow fan enthusiast Dan and his wealth of knowledge on ceiling fans featured here. Can confirm myself that Envirofan Goldlines are among the best industrial ceiling fans one can buy :)
I agree!
Oh and much love for the outtakes. It seriously is what makes me keep recommending your videos to people cause it shows how human even youtube super celebrities are
Oh god that joke. Perfect delivery to get that three-seconds-later moment of realizing what just happened.
I didn't think Alec was such a FAN of these unnamed things, but his energy for this intro is unmatched.
0:11 That joke went right over my head. Ba Dum Tiss!
i don't get it
wait now I get it, they like ceilings because they're architects
@@lordzuzu6437 architects like ceilings, they are fans of ceilings, they are ceiling fans.
@@DatNerddSwaqq omg, now i get it, lol ty
@@DatNerddSwaqq In the spirit of no-effort November, I didn't even think about it, and therefore didn't get it.
I've had to reinstall an old ceiling fan mount before because it was barely put up, and the torque from years of running was working it loose and causing a serious wobble. Amazing how someone could put up a fixture that will be holding a heavy object above people's heads and think a single nail will be enough.
seams he nail the job
Some cool and important trivia about propellers and helicopter rotors. Both of them are wings attached to a spinning shaft. Thanks to their angle of attack they will in fact generate thrust, but that thrust is nowhere near enough to make a helicopter fly or a plane to move forward. What makes their shaft move axially is the lift they generate. On the plane the lift is pointed forward, so the props "fly forward", and since the props are attached to the plane, the plane goes forward. On helicopters, the lift force goes up, and so does the helicopter.
Technically, you could get lift with no thrust if your prop blade has a profile that generates lift with zero angle of attack.
Ceiling fans (and any other fan, to be fair) are closer to modern jet engines. Actually, a turbo fan engine is a big fan blowing through a tube which its cross section area gets smaller and its powered by a jet engine. If you replace the engine core with an electric motor, the whole engine would work the same way.
Thanks for adding in the clarification of what makes propellers work. Isn't the zero angle of attack how stealth works, to minimize the impact that creates sound waves?
You are a colossal dork. I'm here for every second of it. 😂😂
Also, I'm a huge fan of this video.
I clicked to hear about ceiling fans and left learning how Helicopters work. Thanks Technology Connections!
MOM I MADE IT!!!
Friend Dan!
By the way about “jerk force”, in physics/mechanics jerk is the name of the variation of acceleration.
If you derivate position over time you get velocity.
If you derivate velocity over time you get acceleration.
If you derivate acceleration over time, you get jerk!
If you derivate jerk over time you get snap, variation of snap is crackle, and changes in crackle over time are called pop.
Umm actually, the fan does not get heavier or lighter due to its operation. The weight is the same but the rotation of the blades imparts a separate force which acts on the scale.
True, but this is November, and explaining would be Alex expending too much effort.
Good point.
Ultimately force-binning is made up, so they do get heavier or lighter, though their mass is the same.
Really enjoyed Alec's first only fans video
There was one a few years ago looking into why fans with rotary dial/knob controls almost always have the speeds in descending order (Off-High-Medium-Low) instead of ascending order. "Fans-High Is Next to Off on Purpose."
Nonono, you got it all wrong. Helicopters fly not because of the big ceiling fan on top, but because they're so ugly that the ground repels them.
:(
well, at least that means i'm not so ugly that the ground wants to repel me
Thank you for doing a fan video at this time of year and reminding me to clean and reverse my fans.
3:40 woah electricity is heavy
I wouldn't be worried about the torque or thrust, I'd be more concerned about vibrations stressing the mounting hardware.
Don’t call me Shirley.
Easily Video of the Year. Decades of mental gymnastics and mathematics put to rest. Grateful I am!
Most likely, your friend Dan is the world's _premier_ source of ceiling fan knowledge. But your captions said he was the _premiere_ source. I'm confused!
I’ve never heard of him before, so it makes it a premiere to me! 😅
Thank you, Dan the fan man!
3:08 real missed opportunity for the Vsauce sound
This is no effort November, and that's some effort
HOW DARE HE NOT PUT THE SOUND
@@Spiker985Studiosfair enough
Hey you need a junction box for that 😆
4:30 You say 20 pounds, but are those Avoirdupois pounds? Troy pounds? Tower pounds? Merchant pounds? London pounds? Or maybe Metric pounds?
Swedish Hot Pounds.
It's probably more worth being pedantic about the kilograms/newtons distinction. He says a "[x] kilogram reduction in *weight*", but kilograms are *mass*. It would be more correct to say "the thrust exerted was [z] pounds, or [y] newtons, which would feel like [x] kilograms in typical earth gravity". But because newtons aren't used in everyday situations, kilograms is a more human-centric and relatable unit.
Bro is out there answering the REAL questions! Luv from Brazil!
8:44 I'd wanna wear a bullet proof West at least to go near that thing. Ceiling Fans in general are a touch scary due to their exposed blades and because we don't have them in europe, but "mounted" like that and beeing so unstable thats a wholy different thing
we most definitely have them in europe
Europe has south
People should stop saying 'europe' instead of their country. Europe is not culturally unified
They're much less common in northern europe, but do exist, I have one in the UK, and my friend in France has one, my friends in Belgium, Poland and other countries have seen them, but dont have any.
My friends from Portugal and Spain say they are common there though, although I'm not sure how frequent it is compared to the US where they seem ubiquitous.
I love the effort level tbh. It's refreshing. Easy to watch.
