Testing If You Can Blow Your Own Sail | The Chill Zone Reacts

Why doesn't the size of the object matter? So if this is my starting string, when I lift it a foot off the Earth, you can see into every corner. I only need two extra feet so that's 8 feet total and like with this it's just representative okay this is not like that this doesn't mean the Earth is flat the Earth is square bro always It has been, how are you doing? Jack here with another reaction today. I'm going to watch a Mark Robber video that was recommended to me. I know. of this channel because of the few, I guess I watched a couple of them, the takedowns of some scammers that were done a few years ago and I find those videos to be quite entertaining and quite informative, because obviously there are a lot of scams. all not many, all are bad I guess the only exception would be scamming a real scammer, so I guess that would be acceptable, but he, in collaboration with other content creators, has at some point carried out these operations to take down the scam. centers and, uh, I thought those videos were pretty good.

Wilder, of course, has shown reports about the fact that some of the people in these countries I think the last one I read a few weeks ago was about the Philippines, where those Filipino centers have real love centers or all that stuff, wait a moment, it was in relation to a discussion I had with Chad about the whole thing about people getting girlfriends like IA is a little strange now, but yes, there are love centers that were made there, but a lot of the people that worked there They were tricked into thinking that they were actually getting legitimate jobs, but instead they ended up operating as scammers now, although I can feel some sympathy for that, what I can't understand is the fact that not even the local police were ever willing to investigate this, no, people then got involved in them, of course, maybe out of desperation, we were stuck there in that situation and continued to scam people, but I have to say that taking revenge on someone who is stealing the money from grandma or a guy who is so depressed that he decides to invest money in a chat girlfriend is a good thing, well all I'm trying to say is that I know Mark's Works through those videos, but this one seemed to be a little different as it seems title uh

testing

if you can ruin

your

own sales.

I must say that you shouldn't be able to do it. This is not Dr. Ditt nor the whole experiment I'm seeing here in the thumbnail should not work. uh, because of the third law of motion, but otherwise it's a fun recommendation, so let's get into it. I'm about to plug in this fan to test if

blow

ing into this window will move the boat forward and then I'll fly 4,000 miles. to the equator where I'm actually standing in the northern and southern hemispheres because this line here is the equator and I'm here to investigate if this demo for tourists is actually a scam, they basically pour water into this basin and discover 4,000 miles to the, like this Which if you're wondering why I look a little bewildered, it's simply because the equator isn't where it's depicted.

I was born in Cameroon and I know this because my country is literally on top of the equator right there but of course it was moving so fast that I barely realized that I was not traveling from Europe to Africa but from North America to South America. South. I am flying 4,000 miles to the equator and on the northern side of the equator it appears to rotate and drain counterclockwise, but just a few feet away, in the southern hemisphere, the water appears to drain exactly in the direction opposite. It's kind of like you might also have heard toilets flushing in opposite directions on different sides of the Equator and we're here to find out the truth, but I won't stop there because today we're going to investigate six more physics and engineering puzzles using simple proofs as you go.

We move forward because our goal at the end of this video is for you to not only know the correct answers, but most importantly for you to understand why they are the correct answers to begin with, speaking of hemispheres, did you know that the moon in the sky looks like this in the northern hemisphere, like in Canada, but does it look like this? in the southern hemisphere like in Australia it is backwards and while it is a fun fact it is even more fun to understand why and that is why as we all know the Earth is a sphere so if you were Superman standing in the North , if you ever were.

In doubt, if you've been in a tall building accelerated at a speed high enough to be able to see the sunrise twice, then you should know these things. Yes, it's always a shame to hear that someone you know is actually a Bel a flat alha. as they called it, is just strange, since literally the ancient Greeks understood that the Earth was round with individuals as much later in history, in the 13th century. I had to remember exactly the date there with people like Christopher Columbus showing dinkus. stand up and say that, well I actually think the Earth is round, oh my god bro, oh hell what a man, yeah we've known this for years buddy, but they understood this, they even had measurements pretty close to it that the circumference of the earth was actually there, of course, some French ended up finding the exact circumference later, around the era of the French Revolution, but yeah, it should be a problem.

In the northern hemisphere, it would look like this, but if Thor was standing in the southern hemisphere in Antarctica, you would look like this now, of course, the moon here orbits the Earth like this and I'm going to add an arrow to it to help us with orientation and so to Superman at the The North Pole, Arrow would point up, but from Thor's perspective at the south pole, Arrow would point down from his perspective and now I know what you're thinking. If all of that is true, which direction would the arrow point if you are Spider? -Man standing here at the equator, according to our model here he should be on his side and effectively here in Ecuador at the equator.

I'm happy to report that the moon actually appears to be on its side, for a two out of seven fun fact if you do. just insert two pins into a cardboard like this and then connect them with the string and trace it. You'll get my favorite geometric shape, an ellipse, but there's something really special about these two pinholes, they're called focus points and any straight lines. shoot in any direction because one of the points will bounce off the wall of the ellipse and always hit the other focus point and here is the proof because I have a laser pointer on one focus point, a ball of wax on the other and a mirror . surface along the inside wall and now you can see, no matter which direction you point it, the laser always bounces back and illuminates the wax.

I really appreciate videos like this because visualization is often something that helps people the most. I understand this, sometimes later in adulthood, that some people actually have visual impairment to some extent in their imagination. Does that make sense, like drawing an apple? When I'm thinking about how to draw an apple, I can see it in 3 days. I can see it spinning at any and all angles, while some people can only see them in two dimensions. It's a strange thing that I didn't know was a real thing, but it's cool to see the point I'm making here is, of course, that learning things through Vis A visual medium can help people, which, of course Of course, it is not the only correct way.

Many studies have shown that it doesn't matter what

your

specialty is, if you are more of an auditory person you learn best by listening. to Audi books, that might be fine, but it's not always possible to retain information just using that method, so a combination of everything can be very useful, but here's the really interesting part if you build a full size book. ellipse-shaped room and then you stand at one focus point, you can hear even the faintest whisper from anyone standing at the other focus point, even hundreds of feet away, because all sound waves bounce directly off your ears, in fact, this is real.

The ellipse-shaped room was built by John Quincy Adams in the US Capital Building and legend has it that he was a master at anticipating the movements of his opponents who were plotting against him on the opposite side of the great hall and now that you know the physics involved. It should come as no surprise that John Quincy Adams conveniently placed his desk right above this leftmost focus point, the next one at number three. Everyone knows that when you step on the accelerator pedal in a car, the things inside slide backwards and then when you step on the accelerator and brakes, the things inside keep moving forward, including you, by the way, it's That's why we use navy bels, so why the hell, when I'm driving to the birthday party and I have to hit the brakes, the cake slides forward, but the balloons actually move backwards oh, I almost thought I was going to mention the brick because the brick actually moves forward this has everything to do with the inertia of things, right, Newton's three laws, the first is the law of inertia which states that an object in motion will stay in motion and an object at rest will remain at rest unless a force comes to change it and this change is of course something that is observed through a net force, so how do we observe this net force well by looking first? in the mass like if I change here for a moment, I have this book right, my book is, uh, it could have a lot of content, but it's R light, there's not a lot of things in it, it's not made of a lot of things, whereas the one water bottle that is substantially more massive, will have a little more resistance to change if you were to push any of them and that is, of course, what brings us to Newton's second law of motion, which states that the more massive an object is more resistant to change or mass or sorry Force, the net force that I talked about before is equal to mass times acceleration and that net force will once again be important to us when we need to determine whether or not, the

sail

or the propeller will affect one or the other because of the third law of motion that dictates this action V reaction or how stupid dad jokes tend to make it seem like for every dumb male action there is an exaggerated female reaction, thanks dad. that's one way to forever remember the third law of motion, that jokes are terrible, as for the cake sliding forward, well, that's just Newton's first law in action, which basically says that all Things are a little lazy and want to stay still unless a force comes in and tries. to move things and then Newton's Second Law tells us that the more you weigh and the more mass you have, the more force is required to even move you, but this is what we sometimes forget: the air around us is a fluid and it also has mass atmosphere weighs something that's why air pressure is a thing there are tons of air molecules piled up above us and each one weighs just a little bit so we're at the bottom of this pile of dog air molecules that's why you bag of chips expands when you go up the mountains it is because it has moved up the dog pile, now there is less air up top that weighs it down pushing in from all sides and as a little proof, here is a simple demonstration that the air molecules around us actually weigh something when I cast this. balloon on the side moves but doesn't take it down completely now all I'm going to do is take the exact same balloon and just add air to it that's it everything else I like how plan versus Zombies has universally become the soundtrack of use for a popular science explanation.

I did that too, so I'm guilty of doing it, but I also like the example with the chip pack I'm going to use, which in the future is good, it's identical and hasn't changed and yet now it hits the sign , which means we increase the mass just by adding a little bit of extra air because, again, Newton's second law states that the heavier, the more massive an object is, the better it is at hitting things, so in the car, when You hit the brakes, don't you. not just the things in the back that have mass that wants to keep moving, but all that invisible air does too, so when I hit the brakes, the air also moves forward and since that air is denser than gas helium in the balloon, A light balloon is forced to move backwards and that is what we would expect, right, we say that a helium balloon floats in the air or this pingpong ball floats in water, but it is almost more like something heavier and dense, in this case the water cuts sharply towards the front. the line forces the poor ping pong ball up and out of the way, in fact, you can see if we put this jar on its side, the same thing happens in the car, when I give the jar a push, the water flows back, which that forces the less dense. ping pong ball forward and then when it stops the dense heavy water cuts forward, forcing the ping pong ball back, then for number four we come back here on the lake to find out if the

sail

boats are They move when the wind

blow

s in their sails, why not? simplyget a big old fan like this one to propel it through the water.

Now remember action V reaction. What's going on? The propeller will exert a force on the air pushing it forward, which will have to exude a reaction that will push the propeller. Towards the rear, now the sail also acts with a force that should be equal because here we are talking about net forces to that of the propeller, so two forces from opposite sides that counteract each other what is the zero net force, so who shouldn't be moving like the guy in this viral video who uses a leaf blower pointed at an umbrella to move around on a skateboard.

Well, let's think about this with the simple demonstration of a fan that is attached to this train car and what it does. It doesn't make sense, I turn on the fan and it blows air to the right, which direction will the car go right? Of course it goes to the left because it basically cuts off the air and pushes it back which creates an equal and opposite reaction that It pushes the gear forward just as an airplane propeller pushes air back and moves the plane forward. It's no different than me standing on the skateboard. and when I push the watermelons to the left they push me back so I roll to the right again Nate so now let's put a brick here so this car can't move and then let's add a second car here with a candle now when I turn. the fan in which direction this car will move, of course, to the right because all that fast moving air hits the candle, it's like it's being hit by all those little watermelons, so if we now remove the brick and this car wants to move to the left and then it wants to move to the right, what will happen when we connect them and nothing?

Because it's a perfectly matched tug-of-war with each car trying to move in opposite directions with the same amount of force. Yes, that's called B balance actually. It kind of works to move a boat forward, you just have to let go of the sail and point it the other way, but at that point you can also take the same fan and put it under the boat so you can push against the boat much more effective. heavy water instead of just air, which of course is exactly what a boat propeller does, and sure enough, when I plug it into real life, as you can see, I'm not going anywhere, so if we've totally debunked the idea of ​​blowing your own sail so what's up with that guy with the leaf blower and an umbrella on the skateboard?

Well, I have copied exactly your same configuration here and confirm that it really works. I just realized from the sound that can be heard faintly, it's not just the LEF. blower, it's actually the skateboard. Damn, I can't believe I haven't realized it yet. A bunch of kids used to come with those electric skateboards to our store, yeah, whatever is debunked, yeah, it just has nothing to do with it. the umbrella or the leaf blower and everything that has to do with the fact that it is an electric skateboard with the battery stored right underneath, exactly the same as you can see in several of these shots from his video before getting to the last three. including answering whether this tourist demo is a scam if you're like me and love that aha moment when you learn something new.

Well I have good news for you, let me guess Crunch Labs. I'm glad you said it Jimmy, it's true because packing that moment is why I created crunch laabs where you get a super fun toy every month in the mail that comes with a video where I show you all the juicy physics that makes the toy work. Mark won't say it himself, but obviously he used to work at NASA and Apple. He is one of the best engineers you will ever find and he is specifically designing these boxes to teach you everything he learned. He had this water gun that we made and you can flip a switch when you give it to him. someone else and shoots you I mean, it's amazing.

I've played a joke on you a couple of times with this CH Box. I know, so if you want to prank Mr. Beast while experiencing a bunch of those lovely aha moments at the same time, it works. just visit cab.com for more information, that's great, this is the kind of toy I want to give my daughter when she's old enough for it. Now a big question to ask when it comes to the boat is why? so you are both sailing with sales in real life, well it is because we are dealing with a lateral pressure, remember that neither the sail nor the propeller were moving due to the balance between them, obviously, to make a change you need to have a change in that balance this is what we often call principle beri the part that causes the lift there is a whole field of study when it comes to those types of movements called Aeronautics, chances are you've heard of it Arrow coming from the air or from flight and Nauticus from ancient Greek which comes from seaf fairing.

He needed to find the right word to say here, but essentially ship sails are the equivalent of simple airplane wings. It takes varying pressure between the two sides of the sail to accelerate it, that's how it's now hitting number five, it's the craziest fact I know. Imagine I just finished tying this rope around the world, but now I discovered that it was supposed to be one foot off the ground the entire way around, so the question is. How much extra rope would you need to buy to add to this rope to make that happen? Now you might be thinking about doubling or even tripling this amount, but what if I told you that you only need this extra rope of 6.28 feet to be exact? that the circumference of the earth is 131 million feet and yet you only need this extra rope to lift a whole foot off the ground every which way and what's even crazier is that if you did this around the ball of basketball would be exactly the same amount of extra string now the math is just some simple 8th grade algebra and you can see here because the radius cancels out, no matter what size circle you use it always works out to 2 pi or about 6.28 feet of extra string, but If math is not your thing, don't worry because if you pretend the Earth is a square, it will immediately be obvious, yes, okay, one for each side, yes, that makes sense too, why the size of the object doesn't matter so if this is my initial rope when I lift it one foot off the Earth but you can see in each corner I just need two extra feet so 8 feet total and like this is just representative, okay this isn't it, this doesn't mean the earth is flat, the earth is a square, bro, it's always been a basketball, you'd still get the same answer if you tried it in a smaller shape of four sides like your television, which is pretty close to the extra 6.28 feet needed for a circle and the number six.

A while ago there was a Kickstarter that claimed to have invented a floating backpack that reduced impact forces by 86%. Welcome to the future of backpacking. You've never seen a backpack that moves like that or allows you to move like that and this move is Not just for show, by suspending the load, the hover glider reduces impact forces by 80-90%. I really got interested once I noticed a lot of people in the comments section were debating whether this would really help or not, so what do you think this is? a scam, the argument for it not being a scam is that when you wear an oral backpack while bouncing up and down with every step you take, you are working against gravity.

As you move all that weight up and down with you too, in some ways it's like pulling this weight up and down with a rigid rope, but if the backpack were elastically suspended on a track, its own inertia would tend to keep it vertically in the same place, like a gimbal, the only problem is that you have to keep it in the same rhythm all the time, I guess it gets very frustrating if you have an alternating rhythm, I mean, I don't know if that will hit you a certain way or it will drag you back and forth, yes actually, like a rocking chair, that's oh oh The feeling can be strange, so you can still bounce up and down while the backpack doesn't move, it's like replacing that stiff rope with an elastic one, at which point you can see it makes it much easier for my arms to move up and down.

The weight stays in place, but detractors pointed out that all the extra pulley ropes and frames to make the system work are still an extra 4 pounds of weight, and whether it bounces or not, you're still carrying an extra four pounds up. the mountain's top. Also, the video only shows ideal use cases and in real life it probably wouldn't work as well walking on repetition ground and I felt like both sides had valid arguments, so I'm a firm believer in the scientific method. I ordered one myself and then walked a few miles with the regular backpack and then put exactly the same amount of weight on the hoverglide backpack to qualitatively compare the difference so far.

I don't like it, it feels like it's knocking me down, let me try jogging, oh that. It feels good, that's the trick. I feel like if you play the right cadence it's magic, it's not the right cadence, it's the opposite of magical, oh yeah, now it is and then it comes out of the sink, it literally throws you off balance, so my verdict is yes. Flat, predictable train travel can be beneficial, but on any kind of sporadic and difficult walking train it is simply not worth the extra weight and force due to timing issues and for our final scientific challenge we are back here at the equator of Ecuador. to see if this popular demonstration for tourists is actually a scam.

Does water really drain in opposite directions even just a few feet on either side of the equator and, relatedly, do toilets also spin in opposite directions in the northern hemisphere versus the southern hemisphere? Now, as for the toilets, let me just debunk you. That myth was blown out of the gate because if you look closely, the direction of the swirl is just a function of which direction the nozzles are pointing, as you can see here, and with any toilet, you inspect it yourself, but what about sinks? that they only have one drain like in Dem Mo? here where there are no nozzles, believe it or not, there is actually some truth to this idea because of something called the Coriolis effect and it is the same reason you may have noticed weather patterns like this that rotate counterclockwise in the northern hemisphere, in which case we call them hurricanes and clockwise in the southern hemisphere, in which case we call them cyclones and the reason to wait F oh, that was so dumb, I had a Battlefield 4 moment, did you?

Isn't that the one where they are discussing what something like cyclone is called or not called? or typhoon what is a typhoon you would call it a hurricane typhoon is a tropical cyclone it doesn't matter because this is quite simple to understand if you imagine that you have a very large sinkhole that extends from the equator to the north pole in that case A single drop of water in the sink at the equator here takes a very fast joy ride as the Earth rotates and a drop of water near the middle moves at a medium speed, but a drop of water at the North Pole does not. it doesn't move because it's right on the axis, so now when you pull the sink stopper and the water moves toward the center, the droplet here suddenly moves laterally much faster than the slower water that was near the drain , so it comes to the front. of the drain and, conversely, a droplet here at the North Pole moves laterally much slower than the water near the drain, so it lags behind, so when all the droplets are affected in this way, naturally you get a counterclockwise swirl, like a Hurricane Hur where the eye of the hurricane is the low pressure area like a drain and then of course applying the same logic to the southern hemisphere would naturally do the opposite, which which would result in a clockwise swirl, does this mean that the sinkholes actually drain oppositely in the north and south? hemispheres, well, unfortunately not, because the Coralis effect is really only noticeable the further you move up or down from the equator, unless you have a 5 mile wide sink or if you achieve the most extreme conditions. perfect like my friend's Destin and showed.

Water flows clockwise because of the Earth's rotation Water flows counterclockwise because I'm in the Northern Hemisphere Is it real This effect is too small to have a significant impact on the swirling directions of sinks and toilets, at which point it comes down to other factors like the giometry of the sink or the fact that the seemingly still water was actually barely moving when the plug was pulled, so what's up with that tourist demonstration? If you play it and look closely, you can see at the end of its pore. it makes this subtle twisting motion so that the water continues to spin in the direction of the spin, so when the pore ends here, it spins like this and the water continues to spin in that direction andthen after moving the sink supposedly over the equator its pore ends. spinning in the opposite direction and then the water swirls, come on, come on, in fact you can easily recreate this demo yourself at home to see that by copying this method you can also easily get a hot tub in both directions and so So, it shouldn't surprise you. that when I ask this question it works even if I pour the water I was denied the opportunity to test and observe besides all that as the last nail in the coffin if you really look for the GPS coordinates of this place it is more than a football field away from the equator official, which means we were actually in the southern hemisphere the whole time, so instead of real science, this is just an attempt to take your money with nothing more than a lame magic trick where the real magic is all that.

Juicy new knowledge I just transferred wirelessly through that screen you're looking at me on from my brain right to your ninja. Okay, this was fun.
