Blowing Your Own Sail Actually Works

Hello everyone, today I will show you how it is possible to fly

your

own

sail

. It all started with a video that went viral on the Internet showing a janitor using a leaf blower to blow up an umbrella and now propelling them forward. After this, because of that, I made a video showing how this is impossible, okay, three, two, one, it's not going anywhere, but now you remove the board and finally I showed that if you use a leaf blower

blowing

on a flat cell like this and try to move forward you can't move forward on the three two one doesn't work it's not going anywhere but the problem with this setup that I showed before is that I was using a flat candle but what if you use a more traditional cell? that's curved now let's see what happens when I use a cell that directs a lot of the air backwards so I just put a box here and I'll turn on the fan and see if it can

actually

blow forwards so let's go. look what happens when I turn it on now three two one there it goes so this is strange we have proven without a doubt that if you have a curved cell that directs the wind backwards then you can fly forward on

your

own fat let me show you how this

works

?

Let's say this ball here is a particle of air, so if I don't have a cell in this and I turn it on, it goes this way because the blades hit the air and they throw the air out this way and So if the air goes This way, it has to have something to push against, so it pushes against the fan like this, and if the air comes out like this, then the vehicle moves like this, but now, when we put a cell on it that throws out the air. backwards, then what happens is that first the air hits the blade, so the vehicle starts moving backwards in this direction, but then the air hits the

sail

and bounces this way, so the vehicle ends up moving in this direction, so the initial impulse of the air hits the fan.

The blades make it move backwards like this, but then it hits the cell and then it moves forward and as the air keeps going backwards it keeps moving forward, so what this means is that you don't need to think about which direction the fan is pointing. you only have to worry about the direction the air comes out from, for example I have here the most useless leaf blower in the world so the direction it blows I have it curved into a tube and

blowing

backwards so I What this does is it completely rotates the airflow so that it shoots behind it instead of in front of it okay now let's see which way it goes here we go three two one so this device should help you start to realize of what forces are at play when you are directing air wherever the air comes out, you can imagine that there is someone pushing right there and if I change the direction of the push like this, then it is as if there is a force pushing in this direction, so it will just spin it in a circle.

This is the same reason why when you have a hose and you turn it on, it shoots the hose backwards because as if there was someone pushing the hose, the real thing that generates that force is the momentum of the fluid that changes direction right here and shoots backwards. back. that direction pushing pushes the entire vehicle in this direction once you realize this is just a problem of which direction the air comes out makes it extremely simple to understand of course you can blow up your own cell if you turn the cell so that all the air goes to the back, then you can blow forward as if you just turned the fan, but the problem with using a cell like this is that it is much larger and therefore the air does not It moves so fast and the fan blows. it's still on its own and therefore you're blocking the air coming out of it, so you don't get a really efficient method of blowing air back.

The most efficient way to blow the air back is to simply turn the fan or use a completely sealed tube that turns the direction of the air in the other direction, in fact this method of turning the air in the direction you want is already used in fighter planes. Specific fighter jets can turn the direction of thrust in any direction they want, even so they can float in the air, so when you try to blow your own cell, it doesn't really matter which direction the fan blows, it only matters which direction. he ends up going airborne once he hits the cell, so in the end it was the video. with that guy blowing on the fake or really good umbrella, I'm still going to say it's fake because the amount of push he got from that leaf blower wasn't enough to move that fast, especially when he was using an umbrella that wasn't very efficient. direct the flow backwards, there's no way you can get that amount of thrust to move that fast and also, if you're wondering if you could use a cloth cell to fly forwards, remember that the mythbusters almost made this work and Bruce Yani also shows it.

How can you use a cloth sail, it doesn't work as well as one like this, but you can use a cloth cell to propel yourself forward as well, so as long as you direct the air backwards you can move forward by blowing a fan, but it's not very efficient and thanks for watching another episode of action lab.
