Which One Is Larger   Jastrow IllusionThese days you can’t trust anyone, anymore. This one is called Jastrow illusion. It is an optical illusion discovered by the American psychologist Joseph Jastrow in 1889. Oh, how sure I was that this illusion wasn’t possible, and only another hoax, but after I watched the video I was convinced it’s true. Amazing! As you see these two objects, even though appear different in sizes, they are actually exactly the same! I posted simmilar illusion previously, but now I obtained the video to convince you! Click on the image below to see the video. The video was shot in Hong Kong’s Museum of Science.

    Your original post is a real illusion and worth thinking about.

    This video is just a play with the camera lenses – the nearest object looks bigger than the one far away, and thus there’s nothing special on it.

    There seems to be a problem
    Tried to whatch the video but it didn’t work.
    Couldn’t download it, either.

    haha, it’s just the angle you’re viewing it from, really

    This is a very simple illusion you don’t even need to watch the video….

    The 2 figures here are Trapezoids and they are obviously the same size. They both have one big side and one small side, and in this picture they are matching the small side from the top figure with the big side from the bottom picture and taking the photograph from an angle were it’s not so obvious, but you can still crearly see that the figure on top has its big side sticking out more to the left than the one in the bottom…

    If you were to set both figures with theirbig sides matching, you would crearly see that they are the same size.

    um i dont know what slavco means, cause trapezoids are not curved, and there is a chance that the shpaes have different size sides, but to me, it looks like the yellow one is simply further away then the orange one, because of the solid backround you almost can’t tell. however there is some overlap, the red being “on top” of the yellow. however that is just my opinion

    I click on the link and it takes me to a video with an alien in it. It does not look like the right video. That is a bummer.

  9. LoKi says:

    Mike, all fine and well correcting people on their geometrical terms, but it is VERY clear that you didn“t even take the time to watch the video.
    The perspex pieces DO NOT overlap one another.

    Ramen.

    cos its bent

  11. thepwnerguy says:

    well… im thinking they are playing with the lenses. i also think that when the dude took away the red peice, he switched it, and when he mtched them up on each other he obviously took a peice away, but playing with the lenses made it seem it wasnt a sepret part. it might be wrong, but thats what i think.

  12. thepwnerguy says:

    wait, its so simple. they are the same size. the top part is bigger and small part is smaller. look it up on google, look for 2 blue blocks… you will understand that this is a raelly dumb illusion.

  13. Brionny says:

    This is the dumbest illusion i’ve seen tbh.
    The one on the bottoms the closest to the lense so obviously it’ll be bigger but they are really the same size.(Nothing to do with playing with the lense.)Noobs.
