  • JACOB SOBOROFF: Whoa.

  • Well that's just a balloon.

  • Come on.

  • MALE SPEAKER: All right, that was an easy one.

  • JACOB SOBOROFF: All right, balloon in the cup.

  • Oh, no.

  • MALE SPEAKER: What?

  • JACOB SOBOROFF: You didn't do that.

  • MALE SPEAKER: What're you doing?

  • I'm never going to look at anyone's pictures of their room the same anymore.

  • JACOB SOBOROFF: I'll tell you.

  • My assumptions, they were wrong.

  • MALE SPEAKER: Oh.

  • JACOB SOBOROFF: Guys, today we're talking about optical illusions.

  • And I know you think my eyes are huge but they're just normal.

  • MALE SPEAKER: What?

  • JACOB SOBOROFF: You might remember a few weeks ago,

  • we started the show off with the OK Go video, the new one that

  • is filled with optical illusions.

  • It took over three weeks to put together.

  • It is a beautiful thing.

  • That's what we're talking about today;

  • all about optical illusions, things that look one way but are actually another.

  • MALE SPEAKER: Who said that?

  • JACOB SOBOROFF: Who did?

  • MALE SPEAKER: We don't know.

  • JACOB SOBOROFF: That was a video called Assumptions

  • from a channel called Quirkology.

  • Got over 5 million views because nothing in that video is as it seems.

  • MALE SPEAKER: Oh.

  • JACOB SOBOROFF: Ladies and gentlemen, the Hyper-matrix.

  • Whoa.

  • Whoa.

  • Whoa.

  • MALE SPEAKER: Look at that.

  • That is--

  • JACOB SOBOROFF: It's wave in a wall.

  • MALE SPEAKER: What is happening?

  • JACOB SOBOROFF: What is happening?

  • And the reason it says Hyundai Motor Group is because this

  • is part of an art installation called Hyper-matrix.

  • And it's at the Hyundai Motor Group pavilion in Korea.

  • And this comes from a Seoul based artist

  • that the group has called jonpasang.

  • But there are thousands of motors

  • behind 300 by 300 millimeter cubes

  • that are going in and out.

  • The cubes are moving with the sounds,

  • but there's also projection mapping

  • on top of the cubes, which makes this full immersive experience like this,

  • like we're seeing right here.

  • That is not a real guy.

  • MALE SPEAKER: That's a Hadouken.

  • JACOB SOBOROFF: Hadouken.

  • MILES: We're talking optical illusions.

  • LIZZIE: Yup.

  • MILES: This is a really freaky one.

  • It'll make you feel like you're hallucinating.

  • If you have any kind of epilepsy or sensitivity to flashing lights, do not watch this.

  • LIZZIE: T-L.

  • No, you don't say the letters.

  • [LAUGHTER]

  • LIZZIE: O-F.

  • -You can look away now.

  • LIZZIE: No.

  • MILES: Don't look at me.

  • Don't look at me.

  • LIZZIE: You look fine.

  • MILES: That video is from the Science Forum channel.

  • This is obviously a popular video,

  • because it's got almost 13 million views.

  • That made things wavy, like everything was a heat wave.

  • It's created when your brain cells that are detecting motion just get fatigued.

  • So after your eyes look away, the cells

  • that are detecting the motion in the other direction

  • are more active.

  • LIZZIE: You sound like the substitute teacher

  • in physics class that got stuck explaining the hardest thing there is to explain.

  • MILES: I'm When I'm like a gym teacher.

  • LIZZIE: You know, like there's some cells.

  • And they're going to go over here.

  • OK, Miles.

  • We are going to watch the style of dance that

  • is called sock trousers dance, or strumpfhosentanz if you're

  • saying it in its native tongue.

  • MILES: Oh, "strumpfrozenhands," yeah.

  • JACOB SOBOROFF: Actually, it's "strufrozentonsils."

  • LIZZIE: See?

  • MILES: Wait.

  • Wait, wait, wait, wait.

  • It looks like the biggest conjoined twin ever.

  • LIZZIE: It looks horrifying.

  • MILES: Your brain so badly wants to connect the right arms

  • and legs to the right torso.

  • LIZZIE: But it doesn't work, and then you end up--

  • MILES: Just confused.

  • LIZZIE: 4.5 million views on this.

  • That means that 4.5 million other brains have also

  • failed to connect the right body parts and the right--

  • MILES: Yeah.

  • ALI: Earnest, did you ever play with sidewalk chalk

  • when you were growing up?

  • EARNEST: Of course I did.

  • ALI: This guy, Edgar Mueller, takes sidewalk chalk

  • to a whole thousand new levels.

  • [MUSIC PLAYING]

  • EARNEST: I like the people who are like posing on the side.

  • ALI: That's absolutely what I would be doing.

  • This particular artist's name is Edgar Mueller.

  • He's sort of very well known for his 3-D sidewalk art.

  • This particular piece was commissioned

  • as part of the Festival of World Culture that took place

  • in Dublin, Ireland in August, of 2008.

  • Since 1998, he has held the title

  • of Maestro Madonnari, which is Master Street Painter, which

  • is a title I didn't even know existed.

  • EARNEST: OK, what you're going to see is completely real.

  • There's no Hollywood magic.

  • There's no computer wizardry, no wizard computery.

  • What do we have here?

  • Just a couple of slopes.

  • ALI: Wait, but they just did that in reverse, right?

  • EARNEST: I said no Hollywood magic.

  • [MUSIC PLAYING]

  • ALI: What sorcery is this?

  • EARNEST: This was made by Koukichi Sugihara.

  • Your brain likes to take shortcuts, so it sees this,

  • and it thinks that it knows what it's looking at.

  • ALI: Yeah.

  • EARNEST: And it fills in the gaps for you.

  • It was the winner of the Illusion of the Year in 2010.

  • Sugihara-san, you are the best.

  • MALE SPEAKER: I know this is an optical illusion show,

  • but sometimes what you see can mess with what you hear.

  • We did feature this before on the show recently.

  • -Listen to Greg speaking.

  • JACOB SOBOROFF: Bar.

  • Bar.

  • Bar.

  • Bar.

  • JACOB SOBOROFF: Bar.

  • Bar.

  • -If you heard bar bar bar, you'd be right.

  • How about now?

  • -Bar.

  • Bar.

  • Bar.

  • -Chances are, you heard far far far this time,

  • except you didn't.

  • This is a perfect example of something called the McGurk

  • effect, which shows how our visuals can alter

  • what we believe we're hearing.

  • I'll play two tones, and you tell me

  • if they're ascending or descending.

  • [TONES PLAYING]

  • JACOB SOBOROFF: High, low.

  • [TONES PLAYING]

  • Low, high.

  • -If you compare with enough people,

  • you'll all have different answers.

  • It's an auditory illusion called the Tritone paradox.

  • It's created in such a way that the tones contain

  • both a higher and lower frequency in them,

  • but our brains have a preference of which to listen to.

  • JACOB SOBOROFF: Oh.

  • So our brains are different.

  • MALE SPEAKER: Yeah.

  • We have different brains.

  • What this episode taught me is that our brains are stupid.

  • JACOB SOBOROFF: Get with it brain.

  • Stop being so tricked.

  • MALE SPEAKER: What, you're going to let your eyes tell you

  • what to do?

  • JACOB SOBOROFF: So those are some of our favorite illusions.

  • Let us know some of your favorites in the comments.

  • MALE SPEAKER: We have some more optical illusions coming up for you after the show.

  • So stick around.

  • Check those out.

  • JACOB SOBOROFF: Now play us out Young Rival.

  • [MUSIC YOUNG RIVAL, BLACK IS GOOD]

  • JACOB SOBOROFF: I literally don't see anything.

  • MALE SPEAKER: You see nothing?

  • JACOB SOBOROFF: I see it.

  • I see it.

  • MALE SPEAKER: There you go.

  • You got it.

  • JACOB SOBOROFF: Now I'm locked into this.

  • The end.

  • It says the end.

  • MALE SPEAKER: Now you can see it.

  • So now [INAUDIBLE].

  • JACOB SOBOROFF: I feel like now I'm

  • scared to move my eyes back to normal.

JACOB SOBOROFF: Whoa.
