Math Test Optical Illusion


It’s Friday, Friday, got to get down on Friday! Okay, so I didn’t really mean to quote one of the worst songs of all time there. In case you didn’t know, that’s a Rebecca Black song and it’s been dubbed as being one of the worst songs of all time. Either way, I’m just excited, because it’s the weekend! I can already see the sun rising outside and it’s looking like it’s going to be a really good say so far! What are your plans for the weekend?

Today, I have a new optical illusion that is certainly going to mess with your minds. I can guarantee you that you’re going to love this one. One of my friends posted it up on Facebook and I have to say that this is one of the coolest optical illusions that I’ve ever seen. Are you ready to give it a go? If so, scroll down.

Math Test Optical Illusion


Now, I know that most of you probably aren’t a big fan of math tests, but this one is pretty amazing, huh? So, what answer did you come up with? Let me know by leaving a comment below. Most people will come up with the same answer and that’s part of the illusion.

Want to see another cool illusion? Have fun trying to find the fault in this optical illusion.

  • sweet

    I thought red drill >.> close enough right?

    • James Dean

      That’s pretty close! :)

  • prawar

    i thought of a gray axe.

    • James Dean

      Now that’s one I haven’t seen before.

  • Stine

    I thought of an orange drill. Guess I’m rather an oddball.

  • Hank

    Blue Screwdriver

  • .mau.

    Ok, I came out with a blue hammer. But the more astonishing thing is that when I took the test I was thinking in Italian, not in English, and I came up with a “martello” (a hammer) anyway!

    • James Dean

      That’s crazy! :o

  • Eddy

    Big red wrenched. The big ones though.

  • Dylan

    Blue Drill..

  • Myriam

    I thought about a orange screwdriver!

  • Carl Fuglein

    red shovel

  • Dave



  • Christine

    Whoa! That is scary! Usually I just poo poo these kind of “tests” off… but why would the math problems cause you to think of a red hammer?!?

    • James Dean

      That’s a very good question. I hope you liked the illusion. :)

  • Todd

    Yellow & hammer

  • Abby Normal

    Damn! Yellow Shovel. I guess I am Abnormal :(

  • GARY

    no lie, I thought red hammer. WOW!

    • James Dean

      Nice! I hope you liked the illusion.

  • BigJon

    Sorry. I came up with purple and a garden trowel.

  • Phillip

    I thought of an orange screwdriver – does that make me weird?

    • James Dean

      Not at all :)

  • Dian

    Red hoe.

  • Raincloudboom

    I got a Green Hammer.

  • Eric

    Sorry, blue saw….

  • Scott

    Well, I’m different. And not abnormal. (ha!)

    Red Wrench.

    By the way, I would believe the claim that 98% of people come up with red hammer has a fair chance of being a bogus claim. Just because this says so, doesn’t make it a truthful claim. What are the chances a meaningful statistical study has really been done for a triviality like this test? There are a lot of tests like this around, and I’d question their percentage claims. Such claims seem likely to be mostly make believe, in my opinion.

  • dabandit

    orange wrench

    • James Dean

      Orange is close to being red, lol!

  • Penguin

    I don’t think it’s because of the test, if you just asked someone that question they would probably say red hammer as well.

    • James Dean

      You may be right.

  • Kiwibot

    Green Spanner (That’s a wrench for all you American folk)

    • James Dean

      Yeah, I’d say some people were definitely confused, lol.

  • doug

    I said ‘green shovel’….

  • Greg Chapman

    Blue spade…

  • bz

    If you think in an other language you will be of the 2% people
    I mean if English is for you a foreign language.

    • James Dean

      I don’t see why.

  • Paul

    Hmm, I thought of an orange screwdriver…

    • James Dean

      I hope you liked the illusion either way! :)

  • jake galm

    I thought Green Hammer. My gf thought red hammer though. Why do so many choose red? And why a hammer?

    • James Dean

      That’s a very good question. :)

  • l0l

    lol red barrel

    • James Dean


  • Twilight

    Blue hammer.

  • Dag Wretling

    I thought of a blue hammmer…

    • James Dean

      That’s pretty close :)

  • Rob

    So that was weird. I thought of my son’s red hammer. Very creepy.

    • James Dean

      Crazy stuff, huh? Hope you enjoyed it! :)

  • Avid

    Is there any explanation about this? Stop making it creepy.

  • Andrew

    In reality, we only see red, gren and blue. All other colors are created by your brain interpretating the results of you seeing a mix of those colors. Green and blue cells in your eye are actually less sensitive than the red ones.

    Red is the first color we named. If you have brain damage that temporarily makes you color blind, red is the first color you start seeing again.

    Hammers are also the very first tool we created. It is the simplest thing – just basically a rock to hit things with.

    This works by engaging your brain to get it moving then suddenly hits you with a surprise question. You grab the first, simplest thing that comes to you. Red hammer.

    • James Dean

      Very in-depth and accurate explanation. :)

  • maria

    Oh my gosh. When I was answering the last question, my eyes saw the ”QUICK, THINK OF A COLOR AND A TOOL!” Wrench popped into my mid, THEN red. I guess my mind is stranger than I thought. *Wink,*wink.*

  • G

    I thought of an orange saw

  • JOAN

    I came up with a blue screwdriver.

  • Siobhan

    I thought of an orange spade… I feel so special! :)

  • Cattya

    Martillo rojo (red hammer).

  • Debbie

    I said Purple Hammer xD

  • suor de sapo

    I stumbled in a similar test but in a video format from Youtube. Well, it was scary, like one reading my mind, since the image of a red hammer just popped over a dark background in the end.

  • Mari

    Green ScrewDriver

  • Gabby

    Woah! So cool! I am going to show my whole family! I got a red hammer! AMAZING!

    • James Dean

      I’m glad you liked it :)

  • Ella

    red saw

  • say what

    Blue Drill

  • Cain

    Blue hammer. Possibly because ‘colour’ is similar in sound to ‘hammer’ and ‘tool’ to ‘blue’? But then I am a bit of a phoneme->colour synaesthete.

  • Anne B

    orange saw like the one in our shed !

    How does colour sound like hammer ?

  • andy

    blue ruller,mathematic reminds me of ruller

  • srishty

    Amazing.. How can this be .. I thought of a PINK Hammer but it was scary.

  • tabbycat900

  • Florin Slash
