Optical Illusions

I have been working on a optical illusions science project for our science fair. I have done a poster with a bunch of optical illusions, and I even got a certificate for participating in the science fair!

I will tell you theΒ 3 main types of optical illusions with examples:Β  The first type of optical illusion is called a reverse illusion. The first two optical illusions below are this type of illusion. You can see them as one thing, or something else.

Another type of illusion is called a moving illusion. They will seem like the picture is moving, but it isn’t. This is theΒ three optical illusions below.

These pictures are not moving!

Another type of optical illusion is a mind illusion and you will think that something that is there is not there, or something is not there but you think it is there. This last picture is this type of illusion.

Here are some questions for you to comment on:

Did the illusions work for you? What did you see?

What was your favorite optical illusion?

Have you ever been in a science fair?

  1. Dear Margot,

    I really enjoyed seeing your poster about optical illusions at the science fair so I am very glad that you decided to share this fascinating topic on your blog.

    I like the reverse illusions a lot! they have also been fun for me to try and see the different objects. Here is another one that I have always enjoyed.

    My favorite optical illusions was the second moving illusion. I like how it looks like a rippling wave. Do you know how to make moving illusions stop moving?

    The mind illusion is very cool, but it’s kind of hard to focus on because it looks like things are flashing on and off. Very strange!

    What an interesting topic for a science fair and a post. Well done!

    • Dear Mr. Salsich,

      I liked the optical illusion lnk that you sent me a lot. I could see a youngman riding a horse near a waterfall, but I could also see you looking at a old man’s face from the side. It was a very interesting reverse illusion.

      I think I know how to make the moving illusions stop moving. Instead of staring at them really hard, look at the pictures lightly, like when you are looking at a flower or a tree. I am not sure if that will always work though, as the website did not tell.

      Happy Blogging!

      • Dear Margot,

        I’m glad you enjoyed the optical illusion link I added in my comment. I like those types of reverse illusions when there are lots of details to notice. I usually see the bigger image before I notice the smaller parts.

        One way to stop moving illusions from moving is to pick one object, like a flower petal or a seed shape, and really focus on just that one object. If you can stare just at that for a few seconds, the rest will stop moving.

        • Dear Mr. Salsich,

          Thank you for the help!
          I was not sure how you could stop the optical illusions, I was just guessing. I tried what you suggested, and I found that it worked. It did not work on the second moving illusion though, because it keeps fluttering like a kite.

          In the illusion that you had, I saw many things. It was so hard to pick which ones that it was! I was very confused.


  2. Dear Margot,
    What an interesting post and great topic for your science project. Optical illusions are so interesting! We just read a book called Duck! Rabbit! and it’s about optical illusions. The character looks much like the duck/rabbit picture in your post.
    I think my favorite illusion is the one that looks like dancing daisies! It’s amazing to realize that the pieces aren’t really moving!
    My favorite optical illusions are by the artist Bev Doolittle. She is called the camouflage artist because of her style of artistry. Check out this one.
    Great post!

    • Dear Mrs. Hembree,

      Thank you for the great comment! I have worked very hard on this post and I even used most of these pictures on my actual picture. Another student in my class, Emmett, had a post about his science project. I liked the post a lot and I think that his project about Sound was very interesting. You can get to his blog on my Student Blogroll.

      I thought that the website where I got the pictures was lying when it said that the pictures were not moving, but when I printed them out for my science project they still worked and I was really surprised that it was such a good optical illusion.

      I have read the book Duck! Rabbit! with my little sister and she liked the book a lot. It is funny how at the end there is a dinosaur and a anteater and the people can not deicide if it is a anteater or a dinosaur. There are many optical illusions in life that people do not realize.

  3. My favourite was the reverse illusion, the others made me a bit dizzy. I hadn’t realised there were so many types. Thank you for sharing such an interesting post.

    • Dear Mr. Woodnz,

      I liked the reverse illusion the best too. I think the others are a bit unpredictable and hard to figure out. I also know a type of optical illusion called a word illusion. A word is hiding inside a word in that illusion.

  4. Dear Margot,

    I love your post! πŸ™‚
    I think that the first optical illusion is two people looking at each other and a candlestick and I think the other one is a duck and a bunny. πŸ™‚
    Please tell me if I am correct! I could see all of the moving pictures and it was fun in doing so.

    From Your Classmate,

    • Dear Alexandra,

      Thanks for the comment! I liked all the smiley faces! πŸ™‚ πŸ˜† You are right with the second reverse illusion, it is a duck and rabbit, but I have a different opinion (even though you might be correct) on the first illusion that you mentioned and I think it is two people looking at each other, or a black vase. But, I am not sure.

      I liked seeing the moving pictures move too! It is very fun and I liked trying to see if I could make them stop moving or go faster.

      Margot* πŸ™‚ πŸ˜†

  5. Dear Margot,

    Great post! My favorite kind of Optical Illusion was the moving illusion it made me dizzy after i watched it a while. The animal one freaked me out! but I don`t know why it just looks weird it’s beak looks wooden. In the first one you can see two faces it freaky. Keep up the great work! Happy Blogging!

    • Dear Taylor,

      Thanks you for the comment!
      I know that some of the pictures might look a tiny bit scary, but once you know how they will work then it is very easy. I do not know why the beak of the secong illusion would look wooden, but everyone has a different way of looking at things.

      I also looked at your blog and it is very cool! I especially liked your new post!

      Happy Blogging!

  6. Dear Margot,

    Awesome post! I dont like the first one. Because when ever i stair at it then blink I cant see any thing I see orange it is very weird. But still like it I just don’t like looking at it for along time. My favorite one is probably the black dots.What is yours? Does any like sort of freak you out?

    • Dear Cassidy,

      Nice comment!
      I like the black dot optical illusion too. It is very fun to do, but it is kind of scary. I think the ones that kind of creep me out are the black dot one and the one that is moving and it has a green backround. I think that if I could pick my favorite optical illusion besides the black dot one is the floweryish one.

      Margot* πŸ˜† πŸ™‚

  7. Dear Margot,

    Great post! I think it’s a great idea for a post and science project. My favorite Optical Illusion was the vase and the faces. I also liked the moving flower thing. The wave one was also cool. I wish I could have seen your science poster. I have been in the science fair three times doing the same project each year. I did a flower experiment where people could come up and plant their own flower in a plastic cup. Every year a lot of people came to the science fair. Some cool projects I’ve seen in the past are some magnet projects and animal comments and a lot of engineering posters too. My favorite kind of poster is doing it on chocolate. I saw that poster in first grade, and it was so cool! It showed how chocolate was made and cooked and cooled. πŸ˜†

    • Dear Amanda,

      Nice comment! I liked how it was so long.
      I think it would have been cool to see your science project. It still have my poster at home so maybe I could bring it in to class someday. That would be very fun. Also, maybe you could come in someday with your science fair project.
      I think it would be really cool if I could have seen the chocolate poster. I think my favorite one was one where this kid had chewing gum and some questions and you could see if chewing gum helped you get smarter. Sadly, the answer was no.
      I liked the wave and the flower optical illusions too. It was very fun to do and I liked doing those optical illusions a lot.

      From you friend,
      Margot* πŸ˜† πŸ™‚

  8. Dear Margot,

    That was an excellent post. I thought the weirdest and coolest one was the 1st one because if you look at it you see the faces but when you blink it disappears. I do not know what animal it was but it sort of looked like a duck.

    Your classmate Tyler D

    • Dear Tyler,

      Nice comment!
      You were right! It was a duck or a rabbit in the second optical illusion. That was my favorite reverse illusion. I did not know that in the first optical illusion the faces looked like they were disappearing but I guess that can happen.

      Margot* πŸ˜† πŸ™‚

  9. Dear Margot,

    I absolutely love your post! πŸ™‚ In the first optical Illusion I saw two faces and a vase. I really liked the dot one. It was really cool how it tricks your brain into thinking there are black dots on the white ones. I also liked the moving ones. My favorite out of those is probably the second one because it looks like a crashing wave made out of leaves I’ll be looking forward the another amazing post!

    Maggie πŸ˜†

    • Dear Maggie,

      Thanks for the compliment! I agree, one of the cool things about the moving illusions is because they move, and they also look like they are made out of leaves or coffee beans.
      I hope you enjoy my next post as much as you enjoy this one. I also liked the black optical illusion because you could sometimes see all black if you looked at it for a very long time.
      Happy Blogging!

  10. Dear Margot,

    I think your optical illusions are awesome. The most mind twisting was the moving illusions. They looked like they were moving but I knew they weren’t moving.

    Your friend,

    • Dear Erik,

      Thanks for the compliment!
      I think the mind illusions are also pretty hard and mind twisting. I think the one that looks like it is moving the most is the one that looks like a wave made out of coffee beans. I was not lying when I said that the pictures where not moving though! It can be very hard to believe. If you want to get more optical illusions, on Google search type in NEIGH Optical Illusions for Kids. Then you can see really funny optical illusions.

      Margot* πŸ™‚ πŸ˜†

  11. Dear Margot,

    My favorite illusion was the third one when you see the things moving but they really aren’t. In the first one I saw two faces. The second one I saw a bird. In the last illusion my eyes would look in one direction and in the other direction there were black dots where the white dots used to be. All your illusions were great.

    πŸ™‚ your classmate Sam K.

    • Dear Sam K,

      Thanks for the comment!
      I can see why you saw a bird in the second illusion because I saw a duck and a rabbit. I love reverse illusions, don’t you? I like the optical illusion too where you can see white dots and black dots that is one of my favorites. I also liked the third illusion because you can see the flowers moving, but they are not! It is very confusing.

      Margot* πŸ™‚ πŸ˜† πŸ˜‰

      • Dear Margot,

        I don’t get how you can also see a rabbit. I also don’t get how people can figure out how to make things that aren’t moving but your eyes make it you think it is moving, like you said it is very confusing.

        The illusion that Mr. Salsich sent is really cool because I see alot of things. I see a guy on a horse and a guy lying down. And then the mans hair is a river, and behind the river are trees. Can you find them?

        πŸ˜† Sam K.

        • Dear Sam,

          I think that since the optical illusions are so tricky, and cannot explain them. I think that if you look at the bird and pretend that its beak is the ears, you will see a rabbit.

  12. Dear Margot,

    This is Ryan, and I am in Mrs. Yollis’ class. I love your post about optical illusions. The moving illusions really confused me. How do the blue ovals move? They were spinning very slowly. I thought my eyes were playing a joke on me.

    The animal was a buck. (duck/bunny) I could not count how many dots were black because they kept on changing from….. black to white OR white to black-I can’t tell!

    My favorite optical illusion was the animal one because I could really not tell what it was!

    Why did you choose to do optical illusion for the science fair? Did you have a second choice?

    Ryan (Mrs. Yollis’ student)

    • Dear Ryan,

      Great comment!
      I liked making this post a lot because I got to find cool and interesting.

      I liked the black and white dot optical illusion because I could not decide if the dots were grey, black or white. Whenever I managed to look at the dots, they would disappear again.

      I chose Optical Illusions for the science fair because my mom suggested it. My mom also suggested the moon, the animal food chain, and a exploding volcano.

      Another cool optical illsuion that was at the science fair was someone who dropped a few mentos (small candies) into Coke bottles and the Coke would explode! When the person did it with a big Coke bottle, Coke exploded almost 12 feet into the air! I thought that that was the best one there.

  13. Dear Margot,

    These optical illusions worked really well when I looked at them.

    The first reverse illusion looks like a black vase. The second one looks like a duck and a rabbit. The first time I looked a the second reverse illusion it looked like a duck, but when I looked at it at a different angle it looked like a rabbit.

    The first moving illusion worked when I squinted, but when I looked at the second one it moved almost instantly! I looked at the third the black dots kept on moving every second.

    My favorite optical illusion was the third moving illusion. It was my favorite optical illusion because it seemed like it was moving the most.

    Your blogging buddy,

    • Dear Hannah,

      I liked your comment!
      I know that the first does not move a lot, but the second moving illusion is moving a lot! It looks like a wave that will never crash.

      I like your blog a lot! I am going to add it to my blogroll very soon.

      Margot* πŸ˜† πŸ™‚ πŸ˜‰ 😳

  14. Dear Margot,

    I really enjoyed all of the optical illusions you put on your blog. I found that the first one is two faces or a vase. The second is a duck if you look at it one way and a rabbit if you look at it another way. The fourth one is moving or at least it looks that way. With the last one i could not figure out how many black dots there are.

    • Dear Ben W,

      Thanks for the comment!
      You are right with the optical illusions. You are very good at them. I agree, with you that the first is two faces and a vase, and the second one is a duck or rabbit. I can not count the black dots or the white dots because they keep on flickering on and off. It is super confusing.

      I also think that the third and the forth are moving. I wonder why?
