Pencils Optical Illusion

How Many Pencils Are There?

What I have prepared for you today is an old trick that plays with your brains. Most recent example we posted was when you had to count the dogs in an infinite flowing animation. Remember that? I think all of this has developed out from the Impossible Pillars illusion, one we had the chance to post at the very beginning of this site. What you have to do today, is count the pencils. That’s it, nothing special – or is it? Just how many pencils are there in this image? Can you spot where one pencil ends, and the other one starts? Think of an impossible flow-meter, if this looks to problematic…

This trick reminded me of an old story. Apparently, Americans have spent millions of dollars in search for a pen that would work in zero-gravity, on their space expeditions. It took plenty of time and resources for NASA to solve this problem. Russians, on the other hand, simply brought a pencil when they went to space. There you have it – who knows if this actually happened. Would be darn funyy if it were true. Hope we have some NASA employees among us to explain this further!

By the way, we have heavily surpassed the 3,000 subscribers mark on our Facebook fan-group, and our counter is growing fast with each minute. Glad to see so many of you invited your families and friends to join our group! I promise to keep it fresh with stuff never before seen on this site. My thanks goes to all of you who joined…

    200. The rest are directly behind these, so you can’t see them in the photo… :p

  2. chris says:

    There are no pencils , they are candles . I hope.

  3. chris says:

    Hee hee , just noticed 6 , bottom , seven on top .

  4. mr.finder.finder says:

    theres OVER 9000!!!!!!!

  5. Andrew Barks says:

    i count 13 half pencils ;P

  6. Rachel D says:

    The zero-gravity pen story is at least partly true. Not sure about the millions in research part, but they told us that story when I was at spacecamp in Huntsville. I’m a huge geek :P

  7. Care Bear says:

    I prefer pens.

  8. i count 13 half pencils ;P
    but then i decide to buy some brains and i count none, since apparently the new brain wuz malfunctioning and i lost the ability to count.

  9. Rahowa says:

    kinda lame

  10. whocareswatmynameis says:

    i only see 6. and then a half on on the left…so 6 and a half

  11. Denzel says:

    OK PEOPLE you should learn to read the description

    Look at the top of the 1st pencil
    and then slowly follow the pencil down

    ………..
    See it?

  12. what's in a name? says:

    Define Pencil.

  13. mel says:

    ohk there r none because if u look closely, the top & the bottom arent even connected

  14. Mel says:

    I see a giant Giga pecil with seven drawing ends and six erasers… As… one just flows into the other.. THEY ARE ALL COMBINED TOGETHER TO CREATE THE ULTIMATE (and somewhat useless) PENCIL!!!

  15. I'lltry says:

    I have to say no pencils at all. But, there are seven pencil points and six erasers.

  16. Mia Jackson says:

    Erasers are in between the lead, so it’s either none or 13.

  17. Chris says:

    Lol, ncie comments. Anyways i see 13 jalf pencivls oo, thought it is impossible to define the boundaries of the pencils. NIce job.

  18. Kate says:

    How many are there by the way?
    I counted 6 and 7

  19. Joe Ferguson says:

    You must first realize the truth… there is no pencil.

  20. SmokeLavender says:

    I appreciate this image and the other images that are displayed daily. I do not appreciate the facebook propaganda attached to this optical illusion. People who don’t use facebook are people too. Enough with the stereotype.

  21. niko says:

    For me it’s either 13 halves, or none because without and eraser or tip, is it really a pencil? :D

  22. Kris larson says:

    There are seven. counting from left to right the last one is on a curve so the bottom is hidden

  23. kajal says:

    hey guys der r only 6 pencils……………m sure :D:D

  24. manohar says:

    07 pencils

  25. A Snail says:

    I also heard the same space pen story, and I actualy have one of those space pens that works in zero gravity, not that I have had the chance to test it :(

    Whilst it is true, pencils do work in zero gravity, they also give off dust when you write and if they break, bigger bits of graphite will then start floating around the space craft and as for sharpening them again, well lets say I make a mess doing that never mind doing it in zero gravity. All the pencil mess then gets into filters and equipment.

    So, perhaps not such a silly idea spending that much money.

    As for the illusion, yes, a classic pillers 6 or is it 7 things in the picture. Might look better if they where childrens colouring penciles that gradually went through the rainbow from left to right – I think the illusion would probably still work.

  26. Futz says:

    I once saw a space pen and the owner told me the same story. And I think there was one in “Seinfeld” as well. So this pen seems to exist. But a pen isn’t a pencil and it might be the case that the NASA had the idea for the pencil as well but simply wanted to develop a pen, too. Just my two cents.

  27. George Jacob says:

    13 half pencils…. 7 halves on top and 6 halves at the bottom.

  28. Mish says:

    my eyes, it burns! DX

  29. Randy Lahey says:

    I heard the NASA story before too, but was told it is an urban myth.
    Apparently if you used a pencil in zero gravity, the graphite dust it creates, and especially any tips which break off, risks getting into and damaging spacecraft electronics and instrumentation.

  30. qwertyuiop says:

    there are no pencils it is just a drawing
    why would there be pencils stuck on you computer screen?

  31. John Citizen says:

    Umm…3?

  32. gothgirl says:

    1!!!!!!!!!!!!!!!!!

  33. monkeyguy217 says:

    i count 0 pencils they are all pens cleverly disguised as pencils

  34. josephine says:

    7 because that’s how many tips/erasers there are…

  35. whoami says:

    7 pencils with their bottom half cut off, and 6 pencils with their top half cut off. :-D
    Reminds me of the elephant legs illusion. :-P

  36. lilJoeyRoo says:

    There were more pencils. …Many more pencils. I’m not sure if were eaten, ground up or carried off by groups of tiny black hoels fm. LHC –

    lilJoeyRoo

  37. I see seven points, and six erasers, they blend together in the middle.

  38. patko0770 says:

    6. only up side of pencil counts. and i have smiliar illusion, but with elephant legs.

  39. 9 year old says:

    none actully it doesnt show any full pencil

  40. Latisha says:

    great illusion

  41. someone else says:

    There. are. _four_ lights.

  42. Cory says:

    The NASA pen story is partly true, the americans did spend millions on a zero gravity pen, but pencils could not be used as some of the other comments have explained. But a normal pen would work in zero gravity fine, so the money was wasted lol

  43. Shehzad Khan says:

    i see 0 of em cuz of the when i look the sharped pencil and look down there a earaser but little bit lefty

  44. Maria Khan says:

    7 above..6 in bottom

  45. Bbriannanna says:

    i got 13

  46. jackson says:

    its easy 7 look how many gold part they are

  47. Hello says:

    umm…14?

  48. Someone says:

    If You Scroll Up And Down It Looks cool

    >_<

  49. Serch says:

    6 bottom 7 top

  50. jorjeea says:

    6. if you count by the top its 7, but dont do that, count by the bottom. the 7th one is just a top, not a bottom too.

  51. bookitty says:

    actually there are 13 half pencils none of them are fully there

  52. May says:

    None. There’s a bunch of half pencils, but not a single whole one :)

  53. Dr.macdini says:

    Well. It depends on how you perceive the problem
    At first glance 6 full pebncils dig a little
    Deeper there are 7 not fully though
    And then if you concentrate and stare
    At it for a min or so you start to second guess
    Yourself so in conclusion there is no
    Right answer

  54. kooki101 says:

    there arent any entire pencils, merely fading lines with 6 earasors and seven black triangles at the top

  55. notarealname says:

    0

  56. Kurt says:

    None…

  57. WILLIAM says:

    13 i say

  58. Brandon says:

    i put a real pencil up to the screen and the erasers don’t have lead tips and the lead tips don’t have erasers, so i guess the real answer is 13; just like william from aug. 16, 2011 said.

  59. NASAfan says:

    The Russians developed pens as well. It is a myth that the Russians used pencils due to the dangerous nature of graphite dust in the Astronaut/Cosmonauts lungs and it’s conductive and particlate nature near sensitive electronic equipment in zero g. Both the U.S and Soviets used china graph pens which are waxy like crayons.

  60. Kanogias says:

    6 man

  61. logic says:

    1
    There all conected

  62. anonymous says:

    7 but 6 on the bottom
    it doesn’t take a genies

Speak Your Mind

You can add some images too.
