  • what a waste of my time.

  • nice it worked

    

  • It will work for everyone, it just might take some time to find the right angle/distance/etc. It took me a couple of tries to do it. There is a spot on your eye where there are no receptors, but your brain automatically fills it in with what's on either side of it (hence why you can see the orange wall and the bar). However, if it's something like a head or a clock, your brain will not be able to fill it in, and it will disappear.

  • this is bullshit, it didnt work for me :(

  • i tried it but all i can see disappearing is his hair and it never comes back.

  • DUDE. After I covered my right eye, I covered my left, and the cross disappeared :O

  • It took me two tries but I was finally able to not see what he was talking about.

  • it doesn't work for me

  • @onefineeagle i think that means u have downs.

  • ha I'm superhuman bc his head didn't disappear on me... Looks like that third eye is kickin in bitches.

  • if you swing a light and look at the shadow of your head moving side to side then move you head it's really disorientating 

  • lol i moved toward the screen soo close i bashed my nose xD i saw ur head when i moved in closer and didnt when i was far back

  • Its a blind spot we all have in our eyes.  I found it really amazing that i could see the black bar completely!. Neat stuff!

  • I tried it. I covered up my right eye. Moved forward. But I'm half blind in my left eye so my nose hit the screen.

  • I see his head :(

  • Its not an illusion, its a physical inability of the eye to see at a particular location. An illusion is where the brain is receiving an image and then makes assumptions on it that aren't actually true(i.e. the hollow mask illusion where in actual fact you are looking at the inside but your brain is telling you that the face is outwards). The closest this comes to being an illusion is when he raises the bar, and even then, its more a physical blending than anything.

  • @RedEyedMars this guy...

  • It worked... for a split second..

  • Each eyes have a blind spot. (It's a great way to find where it is)

  • I think there's something wrong with my eyes or my perception is messed up. I only went as far as seeing the head get blurry, but not disappear entirely.

  • Cool, it worked. :)

  • it worked immediately. I didn't have to move my head

  • Didnt work

  • Does everyone have a blind spot?

  • didnt work..

  • yeah work couse your body skinn is as same color like a wall.. stupid not an ilusion thats interesting for stupid people (A)

  • cool

  • omfg~!

  • cool

  • BLEEP BLOOP! i got an acheivment

  • wow, it worked. but not for very long

  • great!

  • WOW!

    

  • I achieved something by not seeing his head?

  • @Nuerotronic me neither lol

  • @Nuerotronic when do u ever achieve anything from watching a youtube video

  • COOL

    

  • pickles

  • you lied to me... xD

  • i saw a squirrel

  • @THEIRONMAN9 i saw a dumass with a black stick...

  • didnt work, i could see his glasses and his shiny bald head

  • too lazy to try it but cool

  • Er'

    It didn't work for me...

  • but i have one eye :(

  • 53 people face-planted their monitor.

  • Blindspot in retinas, and continuation of images

  • Worked, but took a bit to find the right spot. : /

  • this is a classic, and i cant imagine anyone above the age of 12 never heard of this before.

    anyway, full screen, and keep your head horizontal. sit up straight like grandma told you to! doesnt work if your tilted.

    now you just gotta find the right distance. also make sure you can distinct left from right.

  • Thats crazy!!!

  • I think it's because the left part of your brain is not doing the right job it is like let me put it this way.... tht X is where the right eye is suppose to be and the man suppose to be the one on ur left eye.. so tht means by doing this you are using your left eye for your right eye and right eye for your left eye... im not goood at explaining stuff lol

  • yeah right

    hh xd !!!!!!!!!

  • he haxxed ur eyes!

  • the bar bit didnt work

  • so the eye has a blind spot. FUCK it works great anyway

  • nice

  • that weird

  • Why does this happen?

  • damn i had to get close the screen

  • I tried this 5 times and I can't get his head to disappear! UGH!

  • @shanferguson did you put it full screen?

  • @shanferguson

    cover your RIGHT eye, and use your LEFT eye to stair at the x, don't look a way from the x and don't uncover your right eye

  • His head never disappeared ....

  • @ClubenguinDustox I think it's a question of dominante eye the brain get use of and most of people seem to have the left as dominant. The guy on the clip ask for masking the right one. Don't try the left since the guy is sit on the left, you won't see nothing but the dark side of the force :) ...Kiding...

  • I went at Lazik MD in downtown Montreal for an exam. I had a test where i had to put a mask before one of my (can't remember wich one i think the right one) eye to see if it was the dominant as for most of the people she said. And the magic of disapearing gizmo was involved meaning that my left eye was the one i use to aim my look on things.

  • The blind spot and the brains ability to mask an enormous defect in our vision is pretty amazing =)

  • it worked for me the first time, but not again XD

  • @ClubenguinDustox Perhaps you should get that checked out ;0)

  • @ClubenguinDustox Somethings wrong with you then. It worked for me the first time. =D

  • not workig for me, and i tried full screen

  • doesnt work with me

  • There's a certain distance where the disappearance happens. That's when you stop moving closer.

  • his head is orange like the background and i fail not seeing his head?

  • wow htta was cool, it worked!!!

  • didn't work for me...

  • daaaaaamn. watch it fullscreen

  • oh lol i learned this from an old kidz show called Zoom years ago, we have a blind spot in each eye.

  • this isnt an illusion this is our blind sopt

  • WTF that crazy

  • it didnt work for me :(

  • Awesome!

  • worked for me.

  • Afte ra couple of tries it worked. Really amazing!

  • did this actually work for anyone?

  • oh shoot! !it works!!!

  • we see the black bar cause your brain fills that in for us.. lovely brain .. i thankyou

  • Doesn't work. Stupid

  • woah! it works! :3

  • i try but fail xD

  • its because of the blindspot in the retina

  • The point is, the blindspot makes us cannot see his head, but then when he moves the black bar to the position of his head, we can still see the black bar! Why the black bar can still be seen even if that position is the blindspot?

  • true

  • wouldent work for me tried about 10 times.

  • got it to work had to tern my head to the right slightly

  • wow it works! i love it

  • blind spot.

  • My God! I totally can't see him. although I can still see the black thing clearly.. just w0w!!

  • Comment removed

  • awsome!

  • Well that messed my vision up for a minute. Cool effect anyway.

  • That doesn't work for me! :(

  • I thought the same thing, but I kept trying, and I found it... It's a small position, relative to your screen. It's a blind spot of the eye, which is cause by the optic nerve crossing over something... but anyways, pretty much every animal has it... I know some don't... but all humans do

  • Yeah I've read about that and seen the effect in other videos, but I just couldn't see it in this one. Pity as it sounds interesting.

  • yeah, when it's a small black dot its easier :)

  • @happyidiottalk you have to put full screen then it will work ;)

  • would you happen to be left handed? that may mess with it...

  • lol that wuz pretty cool

  • his head dissapears and reappears.

  • Doesnt work

  • u did it wrong

  • yay works for me :D

  • Doctors use this trick all the time during a cranial nerve exam. Well done though.

    Sock, try putting it on fullscreen, if you do it right, it will work.

  • nope for some reason i can still see his head, no matter how hard i concentrate on th cross nd not his body

     : /

  • Whaha, cool.

  • Dosen't work

  • this is witchcraft i tell ya!!!!

  • It's a result of your eye anatomy and placement. The retina of the back of your eye is made up of millions of receptor except for one small tunnel. This tunnel acts as a pathway for the receptors to feed the information to the brain. This tunnel is also a "blind spot" such that the image is directed at the blind spot, it has no receptors to detect it, and thus your brain "sees" nothing.

  • Doesent work

  • doesnt work for me. ):

  • HOLY FUK ITS LIKE I HAVE SUPER POWERS

  • Eh.. his trick has a major flaw. Those who are not right-eye dominant will have all kinds of trouble doing this. Best I can get at -any- distance is his head area goes kinda fuzzy, but it doesn't vanish like he says at all. I hate tricks like this.. some people they work, some like me just have to sit back and ignore it.  :P

  • His instructions clearly say to close one eye. Follow instructions and try it again.

  • interesting point... as a matter of interest, does it work if you cover up your left eye instead?

  • If you cover your eye, and look at his head, then the X will disappear

    Check out wiki: Blind_spot_(vision)

  • why??? are you blind in one eye???

  • It will work if you go very very slow and pay close attention. It didn't work the first time for me, than I tried it again but covering my left eye and string at the man, and it worked. Than I tried it the first way again, but had to move my head backwards and forewards to finally find my 'blind spot' so you just have to keep trying. If it doesn't work, your just not paying close enough attention.

  • You are more talented than I am. I am giving up trying to make his head disappear, it won't work for me :(

  • It works if you look at him and close your left eye, the cross disapears.

  • :))

  • it really works!Bcos ur bald?! Just kidding xD

  • Comment removed

  • kewl

  • Guys, this is easy to do. Just try looking at it from different distances, as not everybody's blind spot is going to be the exact same.

    The brain does take the surrounding information and fill it in to make the image appear full. Even before the black bar, it was happening with the orange background, and it happens anytime you close one of your eyes.

  • this illusion works.. it's just that other people can't follow instructions, and are retarded..

    remember, it's called a "blind spot".

    the area when your optic nerve connects to your eye..

  • I know the head disappearing is your eye's "blind spot", and I'm guessing that the fact that you can see all of the bar is that your brain "fills in" the spot that disappears on the bar because it predicts that it should be there. Not sure why, though.

  • worked for me at the last two secs ! xD

  • didnt work for me either, i think sometimes people put these kinda vids cuz it gets thier view ups allot. everyperson that it didnt work for will try it again like 5 times.

  • and yet we're still believin' in evolution. It isn't an ilussion but our brain capability in order to keep all the information tidy. It controls our eye vision.

  • Wow. That made absolutely, 100% no sense. And learn to spell plox.

  • sorry for my bad english... I'm doing my best effort to learn it... thankyou for being so sincere... I know that in Internet people use to call other that way... its easy because we are not in front of that people. But... if you didn't understand what I said, do not open your mouth... pls!

  • c===3  c===3

  • this is bullshit! I learned this in science class!

    there's this area where the optic nerve connects to your eye, or something, where light doesn't get through.. or something.

    also known as, "the blind spot".

    this is grade 7 stuff..

  • Scientific fact: If it didn't work for you, it's because you're dumb.

  • holy crap it works but ur head keeps apearing and vanishing like the boxes in assasins creed

  • didnt work for me, not even in full screen

  • mm .same here ..

  • it works for everyone. just go fullscreen...

  • i tried, didn't work for....since he said wat was supposed to  happen i kept concentrating on his head

  • didnt work

  • Wonder what the deal is if it doesnt work lol... cos no matter what I tried... nada lol

  • incrediiiible..

  • didnt work for me either

  • Wow, that freaked me out. Nice illusion.

  • doesnt work. human eyes keep moving to refresh the image, its impossible to stare at the cross and see his head disappear.

  • worked for me

  • yup worked for me too.....but when I opened my right eye...it had slept and it took me 1 min to recover the sight there XD

  • My left eye must be malfunctioning. =(

  • Yeah it happened with me. Is it because his head is the same color as the wall? What would happen if he sat against a green wall?

  • didn't work for me even with fullscreen,

    But i wished it did.

  • heh, nice one ;P

  • I recommend watching in fullscreen.

  • didnt work for me :(

  • didn't work for me

  • wow thats cool

  • COOL!!!!!

  • sooo... so... you're saying you're better then me... is that it!?

  • fail

  • its just the blind spot from your optic nerve

    not an illusion

  • doesnt work ;D

  • cool if you go into full screen you don't have to sit as close
