Flying cylinder

[shadowmask13]

tnx,,,,never make ny videos like ts,,,,,,,

[VideoGameCharacter89]

looks like your making a pipe bomb...

[gmoney8773]

at 1:51 theres a ghost!!!!!

[blindbrick]

@gmoney8773

Or maybe it is because I am blowing to let the contact glue dry.

[catcute55]

@gmoney8773

moving paper,right?



[gmoney8773]

@catcute55 yes

[LDablo2000]

@gmoney8773 wwwwoooowww!!!! what the crap

[monkeyfresh1]

Cool time lapse

[algravelin]

omg i saw that video on the screen a long time ago haha

[BONETHUG1199]

that dum ass shit

[SuperCommentwhore2]

IT COULDNT BE A WIRE xD !!! No.

[supra60]

Get a bic ballpoint pen, the simple kind with a manual removable cap, take it apart. If you can push down really hard on the empty tube on a smooth surface and let it pop out from under your fingers evenly it will fly up off the table and sometimes even do a loop. Same principle. I used to do this in school and it would really get peoples attention.

[BigWestFan]

@supra60 Yep. I turned a few heads in high school doing this too except I would put a back-spin on a good, light pencil by twisting it (holding onto the lead end) between my thumb and fore finger and releasing it as my arm quickly moved forward--all in one motion. You have to break the eraser off first to make it work well. With a bit of practice you can make a pencil float perfectly level, clear across a room.

[TheAdmiralPancake]

@BigWestFan

Yeah, right.

[waynehowie]

kick...ass.....scissors....

[nathangek]

but i could play with that the whole day... and wonder " how the F"

[nathangek]

Sir. you have BIG scissors

[DRakomol]

can you cut a human in half with those scissors?

[orkako]

Magnus effect

[blindbrick]

@SEEitPRODUCTIONZ

Thanks

[sandrozkii]

do u have scissors?

hahahahha

[Hoolymcn]

wooooooah :)

[ehandford]

moo

[gamejestor]

O.o epic, although it's to much work for me to make something that cant even starty in the air for 3 seconds....

[mariehansler]

Well there goes me making that...no way in hell I could ever find a gargantuan pair of scissors like that...oh well I guess I don't get to waste my time with this...so sad.

[blindbrick]

You don't need the gargantuan pair of scissors, a $100 000 CNC. laser cutting table will work just fine :-)

[maeseatila]

@blindbrick hahaha

cool stuff

[uralegend987]

wow! so gay! i made flying hang glider and can ctrl with my hand.

[dac518]

all that just to drop paper!!! why please reply me why i just make paper airplane and my favorite 1 is a hurrican a cylender just like that the only difference is my cylender has open tops and bottom !

why why why why why why why why why why why why why why why why why why why why why why why why why whywhy why why why why why why why why why why why whywhy why why why why why why why why why why why why

[MCPF1]

how does it work

[blindbrick]

Look up "magnu effect"

[RobinRichardRajan]

@blindbrick Nice video! But can you tell me one thing, if you can create lift by rotating a cylinder, then why don't aircrafts use this technique?

[blindbrick]

@RobinRichardRajan

I dont know, but I think that it produces to much drag.

[RobinRichardRajan]

@blindbrick Hmmm, maybe but do you know about this ongoing project? "icar-101"?? They have a website with that name.. Check that out!

[undersk8cops]

HOW!?!?!?!?!?!?! plz reply

[kr8tos1]

Pro Elite O_O...

[SargentoBombarda]

Authentic flying rod!

[FunkiiMunkii2]

ooooooooooh, yeah... i remember the old youtube :D

[blackcrunchy1212]

Beast.

[KwispyWaffle]

LOL nice scissors. And nice hands.

[TheZombiekiller93]

I made one in science class

[notserpify]

wow!!! did u make it up? anywayz wow!!!

[andrewporter333]

dude thats awsome

[mlim23]

How do you cut so well>.>

[weberstahlherz]

to aviod confusion with magnus effect, coanda effect is always described as the lift force caused by the change of momentum of an external fluid jet. but coanda has nothing to do with this experiment because there's no JET. an easier experiment would be a ping pong ball hung via a string drawn by the water from a sink remember? ok! rest in peace king MAGNUS :)

[weberstahlherz]

this is what fluid dynamics scientists call "magnus effect" which is described by German physicist Heinrich. Magnus, was not a great magician, but he proved that the stagnation pressure slightly rotates around a flying body center when the body is rotating in a fluid like air. relative velocity differences around the body creates distorted boundary layers thus causing pressure difference and also a lift force towards the spin direction proportional to the maximum section area of the cylinder.

[BBoyMkl]

very cool man..its a your project?

[spikefei2]

cool that is some thing cool

[pokemonkiller20]

cool

[kfcqpwoeiruty]

this is aswome make more vids

[meistverkauft]

das geht auch mit einer großen tintenpatronne ..wenn man die auf den tisch legt und von deiden seiten mit den fingern so draudrückt das sie rausspringt .. dabei kriegt die spinn und fliegt weg

[MWAHAHAHAHAAHH]

I don't quite get how it manages to "fly"

[r3ap3r10]

its hollow witch means its light it spinning witch create air to fly or something

[querdenker79]

Nice tape..:-)

[Oxidal]

nice one! I think it would fly better if you used bigger scissors, i think those were too little for the job xD

[pranksters32]

LOL!!! SCARY VIDEO!!! BIG SIZZORZ !!!! like the toy!

[midebbie]

Muy bien hecho amigo!!!!

good!!!

[chickenhousechecker]

lol, I appreciate your flyer, and the added humour!... now to pass your efforts onto my science clubbers, thanks xx L uk

[dwainjjr]

this is stupid

[frankensteinmoneymac]

No...you are stupid...this is really cool.

[benbzn2damax]

WOW THERE BIG SIZAS!!:O

[ogancan]

dude, you really are bored, right?

[maxmacu]

beautifull carpet

[Sampson712]

those are really big scissors.

[deeveezed]

If you put it in front of a fan and kept it rotating somehow it would stay in the air. The circulation generated by the rotating cylinder isn't enough to create lift, it needs a flow stream from the front also to have real lift. That's why it 'hovers' towards the ground - the forward movement coupled with the circulation generated from the cylinder is enough to cause a small amount of lift and slow its descent.

[AndreONEz]

Why and how does it fly? :|

[frankensteinmoneymac]

The coanda effect in part.....where air tends to follow a curved surface and in doing so will create lift opposite of the curve...hold a spoon under a faucet loosely and watch it be drawn toward the water. With a tube the coanda effect would be even on the top and the bottom EXCEPT with a spinning tube such as this the air on top is going much faster than the air on the bottom as it moves forward....thus there is much more lift on top. There have been airplane wings and sailboats built this way.

[Anxamovie]

Bravo e simpatico. Finalmente la prova dell'effetto bernoulli!

[BoomBrush]

thats useing a rubber band. CHEATING!!!

[purplepikmin34]

dude. i bet you cant di that. so shut the hell up!

[BoomBrush]

well i've got somthink to say to you

purplepikmin34 , I'M TIRED!

[seversage]

FREAKIN HUGE SICCORS :o  sweet xD

[BoomBrush]

HOLY SHIT! they are huge!

[plane1233]

string...

[T1MP0SSIBLE]

Oooh, I've unknowingly played with the magnus effect with a beach ball.. lol hit it with backspin to make it float upward.. If you top-spin it, it'll do just the reverse and shoot down.

[T1MP0SSIBLE]

Dude, You have a CANNON!

[CompleteNonBeliever]

Paper plane is a lot less effort and far better

[kriegmeister3000]

one reason not to drink coffee

[redeyesthe20th]

I've had ground bloom fireworks that i throw in the air have a magnus effect, they'ed go up in the air and start to spin and stay in the air for 10-20 seconds.

[THESuPeRmAn1013]

those might just be the most badass pair of scissors ive ever seen...

[Joey1275MapleSea]

hehe drink coffee at the last minute '

[dzidzelis]

cool! 5+

[Imprezaman555]

dude, u could cut a head off with those scissors! how does it work?(the cylinder obviously, not the scissors)

[blindbrick]

I can explain it but I think it is easier if you Google "magnus effect"

[Imprezaman555]

i did, its surprisingly simple for a phenomenon so unbelievable.

[stopjunkscience]

Al Qaeda scissors!

[scorpypl91]

youtube watching youtube

hahaha

[blancoericka14]

great..!!!

[Matrix29bear]

Oh, and for non-GOOGLE searching in YouTube, look for "FANWING" for video of "The Flying Combine".

[blindbrick]

Thanks for the tip.

[Matrix29bear]

A funner variation on this is the "Squirrel Cage" aircraft or "Flying Combine".

You're very cute, energetic, and smart. A wonderful combination in a human being.

[kattejuice]

Cool

[ozzy33334]

haha a youtube video of a youtube video!!!

[FreakyMeYeah]

Awsome !!

[austinpoppler]

i dont get it! how does it hover like that? theres hardly any wind resistance.....

[blindbrick]

Its called the "Magnus effect".

It is the same principle as a normal wing. Because the cylinder rotates backwards the air above the cylinder is going fast and creates a low pressure. Under the wing the air slows down creating a high pressure

[frankensteinmoneymac]

Also the Coanda effect should be mentioned....where liquid or air follows a curved surface and in being forced to do so creates an equal and opposite effect. Like how a spoon held loosely will pull toward water in a faucet. A cylinder would have an equal Coanda effect up and down were it not spinning and moving forward. This causes more air to move over the top, and therefore be sucked down by coanda effect moving the cylinder upward. Magnus effect is the Coanda effect on a moving spinning cylin

[mjaauu]

niiiice=D

[jegoll]

what the!?!?!?!?!?!

[zsurfer]

Think you could run fast enough to sustain the cylinder in flight with the lift from a large paddle? Would its spin gradually slow down?

[xXcandyluberXx]

BITCH THATS CALLED GLIDING

[coollat17]

its actually CYLINDER

[XRayCam]

Those GIANT scissors had a nice effect :) Great fast forward play :) The plane....I could leave home without it. But excellent video quality :) Thanks

[Elainerocks12]

lol kool just put a random paper plane on top of it and the plane can land i think =\

[lostwarrior4]

how does that work?

[warpedwarp]

mmm ok, i don't need a playstation now.

thank you

[sooperdude1992]

you guys are idiots!?!!!

[Jesse872]

dude those scissors are huge!

[icedragon94]

srsly lol

[ronaldinhorox64]

lol that was awsome

[nitsuj1231]

those are some creepy ass scissors

[ghostraper]

dang dude you move like the flash ;) so fast.

[tylerGo1]

I did this for a project on the magnus effect! I had seen this video last year and this year I was given a project where we had to explain a scientific principal and I remembered this one seemed cool, I got an A, thanks!!!!!!!!!!

[blindbrick]

Glad to hear that, You made my day.

[Gunnar120]

(SLAM!!)

[323ReTrO]

That looks fake....has anybody tried this before besides this guy?

[blindbrick]

Its not fake. It is very easy to make, why dont you try it and see for yourself. google "Flettner Rotor" and "Magnus effect"

[323ReTrO]

Now i know it's not fake....but can u please tell me the materials so i can do this cylinder.

[blindbrick]

The material you see in the video is all you need. 1 piece printer paper, contact glue and really big scissors.

[wyteboy4454]

lol does it HAVE to be big scissors??

[blindbrick]

Of course, The bigger the scissors the better it will fly :)

[appppppppple]

hehe anyone who plays sports should know about the magnus effect

[zsurfer]

I don't know if it is the same effect, but a tumblewing paper airplane flies a similar rotation and forward motion. It also flies slow enough you can fly it as a walkalong glider.

[graham878787]

how the hell does that work! Pretty cool! How did you figure it out?

[blindbrick]

I always had a interest in science and mechanics, and read many books with lots of pictures of fascinating mysterious machines. now I'm older I have a lathe a milling machine and lots of other cool tools. With lots of surfing the net for information I finally have the knowledge and tools to reproduce these machines.

I saw this cylinder 25 years ago on a boat from Jacques Cousteau later I learnd the cylinder was called the "Flettner Rotor" and the principle is called the "Magnus effect".

[tiagoadias]

GIANT SCISSOR !!!

[jetto245]

those are some hefty scissors

[walawalawala1]

Music reminds me of a certain movie involving a witch and a farmgirl........

Awesome. I love airplanes that glide and this is even cooler.

Instructions?

[blindbrick]

The music is "Flight of the Bumblebee" from Rimsky-Korsakov.

There are no more instructions, its just a paper cylinder spinning backwards.

[walawalawala1]

Ok? thanks. I was just kidding bout the music by the way.

I tried it as soon as I watched just using estimations and it worked pretty well....once. Then it fell apaprt

[bobinabasket]

wow!!

=]

[monsterfreak4pk]

wow your really fast lol

[kgoody84]

in your high school days i bet you could roll a mean joint!

[graham878787]

lol yeah !

[babablam]

Dude, what's up with your scissors? Nice job!

[VictorSeedorsky]

its NOT flying..!! - its just fall dawn - slowly.. thats it..

[blindbrick]

Your right, its actually gliding.

[TheRZcomplex]

Magnus force xD. The same force that causes a ping pong ball to curve in mid air when you apply spin to it. By the way, did you change the circular ends, It sounded alot harder than paper when it landed.

[blindbrick]

Thanks, I did not know that it was called that. Its all normal paper, I guess the cylinder acts as a sound box.

[starmy93]

OMG!!! WATCHING YOUTUBE ON YOUTUBE!!!

i want to make one of those flying tube thingys.

they look fun! :D

[ohcram22]

those are some pretty intense scissors

[Tartalicious]

Lol, 1:41 smilely face :).  Btw, u rock

[ska8terkid18]

im seroius where do u learn all this because ur amazing

[blindbrick]

[SargentExtreme]

lol the coffe XD

[jerinj4u]

cool

[custard19]

does it need the perfect ratio and scale?

[blindbrick]

I dont know, I haven't experimented that much. The one I made has a diameter of 3 centimeter and a width of 16 centimeter and seems to do fairly well. The disks on the ends of the cylinder are necessary for sideways stability, I made them 5 centimeter. I think bigger should be more stable but may produce more drag.

[frnesbit]

You have certainly proved how most of the ufo story's are false but what about my story [by Ross Nesbit ] very close to your clever exposer . My word in my community is unquestioned by anyone who knows me. I wish you could have been there you might have a different video than you have here . To this day I regret not making my cousin Forrest go and see what was in that field.That was 40 years ago.I would like to meet you.

[blindbrick]

??????

[jcarlosgarza]

me too!! ?????????

[safire96]

sick!!!ty

[mjaauu]

very cute. what was that video showing on your computer?

[blindbrick]

that was "Theo Jansen´s mechanism"

[shakaron12342]

lol

[magicmushroom69]

Is there a name for the principle of how this thing produces lift? thanks

[blindbrick]

Its the same principle as a normal wing. Because the cylinder rotates backwards the air above the cylinder is going fast and creates a low pressure. Under the wing the air slows down creating a high pressure.
