Ariel did some very smart optical illusion advertising in the past, and this one deserves to be mentioned as well. If only they would recognize how much free air time we give them, and decided to sponsor us. Unfortunately, I don’t see this happening any time soon :) Anyway, the latest flick has much to do with our blind spots, and every one of us has them. If you didn’t knew that, I recommend checking Wikipedia first! If you open the picture in full size, then cover your right eye and slowly move closer to the screen (while starring at the Ace icon on your right) – at some point the stain on your left will completely disappear! I fooled around a bit, and did something quite opposite; I’ve made the icon disappear, while the stain remained firm :)  Check the #Ariel tag to see previous illusion billboards by this detergent company.

  1. I didn’t think this one was going to work. Well I was wrong again, it does work! The spot vanished on the first try. I did attempt the opposite eye,but that did not work for me. Good illusion.

    if you cross your eyes the blue blob becomes 3-D and super imposes it’s self over the ad.

    That’s so cool!!!!! :)

    Nifty application of the “optic blind spot” to an ad. I have always been curious at this demonstration of the lack of rods and cones in the eye,at the location, where all the nervers making up the optic nerve exit the back of the eye. each eye has one so you can make the stain or the logo disapear depending on which eye you choose to focus with.

    Scary… Makes one wonder what else we don’t see in our every day tasks, like DRIVING…

    It depends on your peripheral vision. I have extremely good peripheral vision and when I put my eye on the screen I could still see the stain.

    Ok. Tried the ink stain and blind spot illusion. I did what it said but the ink stain never disappeared. I could see it regardless of how close to the screen I moved. I kept my eye on the ACE icon and covered my right eye…could see the ink stain out of the corner of my eye the whole time.

    Reminds me of what my laundry looks like no matter what I use.

  11. Chris says:

  12. ham says:

    ooooooohhhhhhhhhhhh myyyyyyyyyyyyyyyy goooooooooood AWSOME

  13. Shana Schroeder says:

    I remember doing that in school!

  14. John Smit says:

    Works the other way too, close your left eye and stare at the ink stain and the ace disappears. 8<)

  15. Whitney N. Ollivierre says:

    i did both!
    if u just do the opposite then it happens. cover your left eye and zoom in on the stain and the ace logo disappears! things like this just keep me giggling with excitement when it works out! ^_^

  19. Ryan says:

    You can do the opposite too, cover left hand, look at stain and the ace logo disappears! Great trick

  20. Andrew Barks says:

    it proberbly just dissapears because your nose is in the way i dont think its got anything to do with blind spots

  21. John says:

    Andrew Barks, you are a total and complete DUMBA$$. It has NOTHING to do with your nose. Moron.

  22. Dolphin says:

    It’s a cool way to advertise…It also fits the product…Very good job indeed!

  23. Rosalie Wanderscheid says:

    I was surprised at how easily and quickly this worked for me. I was able to make either side disappear, as suggested. Very cool! Kudos to Ariel for their clever advertising campaigns.

  24. Josh says:

    If I covwer my right eye, I don’t see much anyway. Yet another ariel ad that doesn’t work for me :(.

  25. Josh says:

    Wow, you have quite a nose then…

  26. bored says:

    wow thats so cool!!

  27. Peter says:

    All eyes have a blind spot – it’s the space in the back of the eye where the optic nerve goes through the retinal wall and connects to the brain. Richard Haviland – it works with the other eye too, but you have to look at the blob on the left, and the ACE logo will disappear. Kimon – that’s why we have two eyes! The vision in the left eye overlaps the blind spot in the right eye (and vice versa) so you don’t notice it. And for anyone who claims this doesn’t work, perhaps you have a wireless connection from your eye to your brain! For anyone with an optic nerve, this will work every time :)

  28. Gordon says:

    The distance for my right eye and the left eye are almost the same. I would have thought that they are identical. Perhaps something to do with nedding glasses…

  29. Rachelle says:

    This doesn’t work for me with either eye…. why?

  30. KeithR says:

    I really like this stuff. Spend way too much time here. Have to make myself take a break!

  31. cheyenne says:

    yea me2 georgey goldsmith i could still c it.

  32. hmm says:

    It took me no time at all to dissapear the blob but, I couldn’t seem to make the icon dissapear. In fact I have always only been able to “blind spot” something looking at it with my left eye. Is that genetic, normal, or just bad angling?

  33. z2d4th says:

    on the other side, cover your left eyes and focus on stain ace will dis appear

  34. Abagail says:

    if you cover your left eye and stare at the ace spot it’ll all turn black try it!

  35. Shelly says:

    Doesn’t work for me….guess exceptional periphial vision will not allow you to fool yourself

  36. Bunnasaur says:

    I made Both Disappear. But not at the same time.. ^-^

  37. Gabriella says:

    As soon as I covered my right eye, it dissapeared.

  38. Juggernaut Error says:

    works both ways, with both hands
