15 Optical Illusions You HAVE to Try

[@daveking3494]

Exactly the same thing happens with our hearing as well. In music, if you just hear a C major chord, you assume it’s a piece in C Major. but depending on the context of the music following it, the piece might actually be in G Major, or F major. This is common knowledge, among musicians and composers. It has been used for hundreds of years to fool the listener, which makes the music more interesting! You could do a whole program on how our ears fool us as well.

[@B30pt87]

I would love to watch/hear a video on audio illusions!

[@notmyworld44]

That's precisely like when Beethoven started his C-major Symphony #1 with an F-7 chord. Interesting observation here.

@@B30pt87 Start with Shepard tones ... They are seriously creepy ... kzbin.info/www/bejne/pILShpJoetF5Z5Y

[@kirajlerner]

In the "Which way is it spinning" illusion, it's even more complex than explained by the narrator. While seeing it turn horizontally, one might see it spinning to the right or left--or swap between both, if you're capable. And when seeing it as vertical, it's possible to see it turn towards you or away from you. What a marvelously constructed illusion!

[@michaelme1548]

I can only see it vertical when they block off part of it. I guess my mind doesn’t want to accept that possibility.

[@ctakitimu]

I love the way our brain constantly edits the world before presenting our consciousness with a picture of what we see. I saw a cool effect watching a guy slowly dribble a basketball while walking away. The ball hit the pavement at the same time as I heard the sound but only up until a certain distance when suddenly the 2 events were separate, sound and visual event. It wasn't gradual, it was sudden. Like my brain said "Yep, I can't match these two things up anymore to what you expect to experience". It's weird that it's sudden and not gradual. How much other stuff is my brain editing?

[@B30pt87]

All of it, actually.

[@ctakitimu]

@@B30pt87 Well yeah, considering we're just brains in a pitch black container making our best guesses about our environment

[@notmyworld44]

Another very strange optical illusion: You are riding in the "bed" of a pickup truck. You are facing backwards so the passing scenery is receeding quickly away from you. You arrive at your destination and the truck stops. Now for several minutes everything in your field of vision looks as if it is rushing toward you. This is truly bizarre, and I have experienced it!

[@andymcneil7085]

Even more interesting too me as I have only one eye and I’m colourblind.

[@sandrainthesky1011]

That last one is WILD! Try looking at the pattern then look into your room, everything moves in waves, so freaky!!!

[@Simonskistunts]

[@devensaiz7039]

It is honestly like tripping on shrooms. That last one😮

[@origamiswami2275]

I liked that peanut brittle staff illusion.

[@baronvg]

I refuse to believe there are rabbits with sharp-ass Vulcan ears!

[@thierrypauwels]

This last illusion is well-known by people travelling by train. If you are looking continuously outside (what I often do), when the train stops, you get the impression that it is going backwards.

[@patriot9455]

I wonder if railroad locomotive enginees and brakemen would see these differently, after years on the train

[@TheMangoMussolini]

hehehe The Girl in the Field got me....I don't think I ever would have seen that.

[@sexobscura]

yep that one *was* pretty cool

[@mikehorrocks2909]

Same. However even with the focus off of the popcorn I was able to switch between the two. Weird.🤪

[@Lux7355]

Trippy, I doubt I'd have seen it without help, though in fairness, this is a pretty small screen, Idk if I would have seen it if it was bigger or not, I'll never know now, that bell is rung lol.

[@joanfoxwright4221]

You've blown my mind. I never saw the popcorn bag until you told me. Yikes!

[@ludicrous7044]

Your mind didn't LET you see it until you changed the program!🤓

[@notmyworld44]

I was especially entertained by that one!!!

[@zaizoesclashing7103]

5:20 i am able to focus enough to see it both ways. But at first i saw it going horizontally. But it takes alot of focus to flip it lol😂

[@philippegilson]

Hello ! N° 15 is amazing. N° 14. I see black and blue lines but no circle. N° 13. I can see the perspective trickery. N° 12 "dulaxis". I don't see any difference in the spinning because there is no spinning. N° 11. I don't see the circles changing colours. they are all "egg" coloured. N° 10. The vapour has no colour. N° 9. The illusion is amazing. N° 8. I immediately noticed the texture difference between the background and the popcorn bag. N° 7. Indeed, the illusion is there. N° 6. You could think it's a rabbit. But it's a raven. N° 5. I use this technic in wood working. N° 4. The orange discs are the same. N° 3. I don't use computers for that. It's too easy. N° 2. I don't see any colour change. N° 1. After concentrating in the middle circle, I don't see colours. And after that I don't see anything moving. I don't smoke any weed. Phil. Peace.

[@williamstier6445]

the letters in the trippy illusion at the end spell out the statement "we don't live in a world of reality, but in a world of perception".

[@MysteriousBenedictBrain]

Yes! Glad someone pointed it out since the narrator behaved as if the letters were irrelevant.

[@Merlijnvv]

The checker board squares within squares create diagonals in a chevron pattern, and the chevrons are all pointing toward the center. This gives the illusion of a central summit. At 18:30 the same effect you see when staring at a floater for some time when fishing. The small waves have continuous motion. Then when you look at the grass in front of your feet it will seem like the ground has become a swirly mass.

[@wayneyadams]

5:32 It is really cool they way it spontaneously changes rotation from horizontal to vertical and back again. It's almost magical.

[@alexanderscott3647]

on the last test 18:33, if you pause the video you'll see completely irrelevant text in bright white background "balance, trust adversity, friends, next play" and so on scrolling in the back ground. No obvious connection to that visual test. i figure a tiny bit of visual deceit here just to help get the authors point across here.

[@rubber_ducky5x]

Every time I saw this video I decided to scroll and it’s changing color from black to white this video is cool

[@firstman9273]

If you do the last one with one eye closed, when you then close the open eye and open the closed eye, i..e. switch them over, the wavy vision is only in the eye that was looking at the patterns, the other eye is rock solid.

[@lynnwood7205]

Once in 1967 from the shoreline bluffs north of Duluth overlooking Lake Superior, the sky overcast and gray matching the color of the lake, I observed an ocean going freighter halfway in the sky. The atmosphere was moisture saturated, this moment being just a brief interlude during days of constant rain I thought at the time the illusion was because there was no delineation of horizon between the color of the sky and color of the lake water. the lake water at that moment being of the same texture as that of the sky. Perhaps a Fata Morgana?

[@airfunmachinery8655]

We receive all kinds of information from the outside world, and the brain processes the information received, driving the neural impulses that internalize our own cognition. On the other hand, we have built a more powerful processing system internally, which can also generate some impulses spontaneously. Dreaming, for example, is an interpretation of internal information.

2:09 I swear there was a blue mist, until you zoom in, bad brain.

[@arubaguy2733]

The "dual axis" was strange enough when I could see it turning horizontally changing directions sort of randomly. Later when it was revealed that it can appear to spin vertically also...things got doubly strange. I believe the brain functions of higher life-forms will never be duplicated by microchips. The complexity of the biological brain still far exceeds even the most powerful supercomputers. Computers will always be much faster at their tasks, though.

Most of these works when I was tired and fell asleep. Bt after watching it again. Right as I woke up. Most of them didn't work. I eyes and mind didn't mix or confused colors. This didn't move like they had when I was tired. Maybe because my brain has not fully awaken???

In the final illusion, why do you have faint white text moving across the image of black text from right to left? I checked and it is there whether you look at the illusion or not. In fact you can pause the image and see the white text.
