So, to collect the tricks: 1) He moves his left hand under right between 01:00 and 01:03 2) He touched woman's back at 07:19 with his right hand. 3) 10:47 He uses his leg to guide the guy. 4) 13:58 Trick is called "Bologna Bottle", google it. 5) He touches three out of four cups at 17:04 - 17:12, the one with the spike is heavier, so he knows which not to crush.

TED Talks are for people who want to learn things. Magicians who don't tell how their tricks work don't teach anything. TED Talk is no place for magicians like that.

One thing I learned late in life...The best liars never lie... They tell the truth in a way that you will interpret it wrongly...the way they want you to.

The raising hand magic is simple. If you watch the video again (especially the part when the lady was standing up pointing finger to the guy), you'll notice that the magician gave hints to the guy whenever it was time to raise or put down the hand, by stepping on the foot of the guy. The magician did not necessarily lie to anyone because he did say that "raise hand when you feel certain pressure" (not indicating where the pressure was going to be, here could be a pressure on the foot). The breaking bottle magic is also simple. The magician said the bottle was a coke bottle, but it was not. It was a special magic tool which could be purchased in any magic shop. keyword: Bologna bottle. The 4-cup magic used similar concept of the raising hand magic. All the audience were fooled but the participant and the magician. The plate with the spike on it was visibly unique (darker color or marks) in small distance so the participant could see it but the audience could not. In the performance, Magician asked the participant to decide which cup to be destroyed. The participant knew which cup has the spike in it by differing the plate visually. He certainly would not want to get injured by the spike.

I cant believe nobody else noticed or commented on the fact that the volunteer male on stage was wearing a suit with socks and sandals.

10:43 Look at his left leg.

It's a mix of magician tricks and psychological methods. I kinda wish he laid it out though. The first one is he just straight up changes how he was holding his hands together when the camera cut. This actually works live, because when he did it, he was correcting someone, so nobody would notice the shift. The second one likely involved the mask simply being heavily tinted or the nose gap being ill fitting on his face and the hood was only opaque on one side. The third trick is also pretty simple, and let's give him the benefit of the doubt, and he actually never met these people before, simply because it would be more impressive for the 4th trick. But in this one, he barely touched her, but did it in such a way that it's really hard to notice with all the other movements he's doing. The fourth trick is where it gets interesting. when he says it's not hypnosis, he actually means that it's definitely hypnosis. You can actually hypnotize someone rather quickly if you frame it right. The only reason it normally takes so long is because of your preconceptions about how it's supposed to work. Next, when he sits down, he has his heel on the guy's foot. The only reason he's not complaining is because hypnosis, and it's also vital that he wipe the person's memory before letting him go so he doesn't give away the trick. If you want to learn how to train an assistant that you never met to follow a simple queue in a little time as possible, there you go. Fifth trick is literally exactly what you think it is. Broken glass sharp, put sharp glass in glass bottle, shake and boom, scratches plus resonant frequency equals exploding bottle. The sixth is a cold read. Start with the most common amount of letters, then next most common until you get a reaction. After that, most common first letters until you get a response, and so on until you gather enough clues to be certain that you got the right one. the responses are subconscious, so they won't even be aware that they're giving it away. The seventh can be one of two things. Either a mirror, or a marked block of wood. I'm leaning towards the wood being marked since it's an irregular substance and easy to have marked beforehand. The second part is, once again, the mask being ill fitting around the nose. Plus, it's easy to give someone a signal when your in direct contact the entire time, and when there's a spike somewhere in there, if the magician gives your hand a squeeze, you better pay attention. Btw you're welcome.

Everyone's saying that he shouldn't be so popular because his magic is fake, but the whole point of the talk is that he's deceiving our minds.. and he's darn good at it

Re the car illusion--ask yourself, why a mask AND a hood? Surely either would be sufficient, so why both? Because when he puts the hood on, we can't see that he's pulled the mask down onto his cheeks or shoved it up onto his forehead, and he can see through the hood. That's why he keeps telling the girl to watch the road, focus on the road--if she gets a good look at his face, she'll realize she can see through the hood and therefore, so can he. The hood is there to block our vision, not his.

i found his trick ... when he sits at the table and tells the lady to point at the guys forehead look at his left leg...he tips the guy off( he lifts his foot up or down ) so he knows when to move his hand ('-_-)

1:00 he froze the screen so we couldn’t point out that he just moved his arms around

I'm with everyone else. As a show, this is very entertaining. As a TED,. it's disappointing. As a TED, I would have expected him to help people understand how the tricks work, so that when charlatans and quacks do it, they will see through the misdirection.

Good magic tricks but could be better....I apologize in advance if some of the comments have already mentioned my remarks.1. Trick 1: Obvious trick: The magician quickly touches the female subject at 7:20 in the back with his right hand. The touching was accentuated with a full body movement (audible) of the magician towards her, to make sure she doesn't miss it.2. Trick 2: I am NOT sure how it was done. If I had slow motion capability, I'd focus on the magician's fingers to see if they touch the female subject's arm when the fingers go from below her arm to the upper position. 3. Trick 3: I am sure of it...watch: At 10:48, 11:05, and 11:15, look at the magician's left leg touching the male subject when he wants the subject to move his hand. Simple.Note that the male helper was recruited to help. Notice how he was picked out QUICKLY (before someone else stands up and volunteers to ruin the trick). The magician took his tome to pick the female helper because it didn't matter. Now the incident with the phone ringing was staged and was supposed to signal that the helper didn't know he was even going to be in an act, suggesting he was a random guy, which is why his phone not shut down. This poses two problems:a.) No one else's phone rang during the presentation. Why? It was a Ted Talk presentation being taped so everyone was TOLD to shut their phones off.c.) Even if you assume that the phone ringing were a REAL incident, someone (either the presenter or another person in charge) would have reminded the audience to make sure their phones were off. Didn't happen. Someone in the room placed that call.b. The second problem was this: why did the phone only ring ONCE? Because it was not a real phone call, it was a misdirection.

but why didnt he explain the principles of his magic to us? THIS IS NOT A TED TALK just a magic trick show.

He used a piece of hard aluminium oxide ceramic that is found on spark plugs to break the bottle the ceramic on spark plugs even a small piece slightly thrown at glass will shatter the glass

1:01 it's so impressive how he completely stops time to hid the switching of his hands here, really shows the power of the mind

I was kind of hoping that he'd actually explain how this all works. That kind of thing is sort of the point of TED Talks.

1:00 - cut and hand twist change. watch his elbow - it was on top before the cut 3:06 - he puts a device underneath the blindfold 7:19 - he touches her back 7:46 - his hands are close enough to her, so she can feel a wind. 3-4 moves just to make sure. And when he saw her smiling, he knew for sure. 10:47 - his leg 13:57 - chemical reaction? Prince Rupert's drop? 14:14 - really awesome face reading 16:00 and after - magnet sensitive sensors inside/under the table?

This isn't a collaboration its simply the power of suggestion.

7:17 is some top tier asmr for a moment

Being a TED talk, I would have assumed at the end he would have reinforced the point that all of the tricks and not magic or voodoo or psychokenises, in that our brains have been decieved. He said it in an offhand way at the beginning, but then spent the entire rest of the talk appealing to supernatural as he performed. That made it seem a bit open ended or contradictory. Would have been better if he actually revealed a tiny bit of the methodology at the end, not necessarilly to give the trick away, but to explain *how* our minds are being decieved. There are plenty of videos on youtube showing how to perform some of these tricks, so its not like he would have been ruining the trick for anyone who honestly wanted to find out how its done, but being a TED talk... I just expected less of a show, and more of, well... a talk.

At 7:20 you can see his right arm stroke up her back. The hand part is a camera trick as well, he's gently brushing past her arm but the way she describes it is vague because she can't actually see whats happening only feel it. He even leads her to the answer he wants by asking "was it a tickling sensation". The other guy is his accomplice. The next part about the pressure is done conveniently at a table to hide the signal he gives him to move his arm up or down, he nudges him in the leg with his foot. At 10:50 you can actually see his leg move. 14:11 it's obviously something to do with the bottle or shard of glass, not sure what but clearly it isn't energy created by though. 17:45 he signals using his hands which cups are which and where to move them. MAGIC.

7:18 look at his left hand while he took his hand to her back for tapping in her back

7:44 look he wringles his fingers to get a thread through which he scratches her hand 🤭🤭

He says only when u feel the pressure, he didn't say where the pressure was going to be, we assume he's talking about the mans hand, but the man with his eyes closed feels the pressure on his foot, the deception is with the audience. The man with his eyes closed feels the pressure on his foot, and he's instructed to move his hand when he feels that pressure, we are being deceived into thinking that the pressure is magically being felt without being touched

He"s a really bad magician. @7:18 He touched her back, He made the mate look at her eyes. @8:17 you can see the object he touch her with. @11:15 he used his left leg to signal the guy to drop his hand. The coke bottle trick was nothing but science. It's called Bologna Bottle. Before he got on stage he heated the bottle and rapidly cooled the internal part of the bottle. He could have used the bottle to nail a nail through a board, but the piece of glass, when shaken within the bottle created a very small scratch which was enough for the bottle's mass to become unstable and blast a part.

One of my favorite TED talks is "The Art of Misdirection from Apollo Robbins" because that's a talk where he shows off his skills and it's great to watch, but he actually made you think and he showed you what he was doing. This guy was fun to watch, but I didn't learn anything or question myself to anything. Kinda bummed about that.

Damn people in comment section are more brilliant than him

10:36 look at Keith's left leg as it press on that guy feet "only when you feel the pressure," he said. he did not specify what kind of pressure because the audiance thought it was from his hand. but the pressure that he ment was from him using his feet

Haha i like how they put "How to spot a Liar" as the next video...

Trick with cups: the way he wore the blindfold he could see under the fold what was happening on the table. The spiked piece is a bit heavier than the other three and has different balance. We did the trick as kids.

The showmanship he has shown is just brilliant! This was worth watching at least once!

Keith is so good at deception. Very cool to watch. At 11:05 you can see his leg rise, releasing the pressure on the guys foot. The guy has never been told that the audience is watching the woman's hand, He thinks he's supposed to be reacting to pressure on the foot.

It seems like a real TED talk at first... but that's only an illusion!

Car trick: The eye mask he uses has a loop that goes under his nose (3:11). He pulls it down from his eye in the guise of adjusting the sack mask (3:19). He can see through the thin sack mask.

He starts using misdirection right of the bat by repeating "slight of hand". The focus is now off of his legs. Excellent mind control. Thank you.

Look from 10:57 to 11:5 leg moving signal under the table :D

I was very impressed …. until I read the comments section.

Keith Barry was the chief magic and mentalism consultant for Now You See Me 2.

that bottle trick was just simple chemistry, and the seeing out each others eyes was the magician remembering the route

If everyone in the comments section can only see this video as a bunch of magic tricks, then you haven't yet realized the point he was trying to make: "training your minds in the art of deception". He gets your attention to follow where he looks and what he points at, but not the actions he performs when he's not looking at it. This is everything that he explains in-between the video as well around 5:45. > "TED Talks are for people who want to learn things." Yes, and today I learned how people focus their attention when told what to do.

11:00 watch Keith's leg!!!

He said he had the car not gimmicked and he could not see through the blindfold. Both are true, but the blindfold itself was gimmicked so that he could take it off when the 'bag' was put on which was also gimmicked. You can actually see through the bag if you pull the bag in a certain way. The girl couldn't see anything when she had them on because she didn't know how the gimmick worked

legend says-and the legend's right-that i still have blue balls waiting for him to explain why this phenomenon is what it is

Amazing how they still do the bottle trick. This is a specially made bottle where the surface tension is greater inside than outside. My chemistry teacher in High School showed us this.

1:00 i like how the video freezes like when he does the move so i cant see it.

That car was the first “Tesla” u can’t fool me

At 10:28 the guy with his eyes closed should have stood up or asked if he was talking to him because if his eyes were closed he wouldn't have known that he was pointing at the girl and asking her to stand up so I think they had this rehearsed

Watch his left leg at 11:03. When she lifts her arm his leg does something under the table to alert the guy to lifts his arm.

11:04 look how his left foot moves to guide the guy. "magician" like him you can hire them for a kids party for 10 bucks/hour

11:15 the trick is explained. Look at his left leg. It goes down as soon as her hand goes down signaling the man to lower his hand. 👍

最後に笑うのは私だって言ったでしょう？がめっちゃ好きwwww

i was hoping to see some real brain magic, but it was just simple tricks :/ and tricks with "random" people participating are so unreliable :/ i had a friend "magician" and i was always the "random" guy at his shows

Breaking a coke bottle is a well known magic trick. Once you scar the inside of the bottle with a piece of glass (or sharp metal, etc.), then the glass breaks easily.

i watched this video maybe two years ago and wondered how he did the whole pressure act and i watched it again and im sorry to say i dont know how i missed his leg moving under the table

Keith uses his left leg, he lift it up to simulate pressure up, he lifts down to simulate pressure down, along left hand fingers to make squeeze noise to give glue to person sitting on the chair. He hides his left hand fingers using right hand palm. The one he shown on the Video was not supposed to be real drive, as you can observe too many cut and clip changes. Regarding the lady who raised the hand, she had pressure on her hand while raising her hand couple seconds, having certain close move there was electro effect on her hand, she believed that her hand been touched. Wonderful illustration, except the video part.

At 1:00 he says to a member of the audience: "yours are the other way round, so swap it around", so that he can change his position of his hand, camera turns away to the audience.....

lol i love how the camera glitches at 1:02 so he can switch his hand around

19:06 beautiful transition of mode there, Keith. ;)

that glass coke thing has something to do with the melted glass droplet which explodes when its tail is broken but is solid all the way around.

The only amazing thing is that anyone trusts some guy that they have never met before.

He most likely touched the guy's foot behind the table when he started to "realease the pressure", and since he didn't randomely select those two audience members (for instance by throwing out a ball over his shoulder) they were definitely in on it. There's nothing in illusionary arts that prohibit you from lying.. ^^

The first one when he goes off screen he reconnects his hands normally and just turns them upside down to look similar to before

17:21 Keith: Is there any way to see through it? The man *saying 'No' while closed his eyes*

The first thing he does is a very well-understood and a very old magic trick called "Hidden Touch". It's one of the easiest tricks to do. Any UKposts commenter can do it with about five minutes training. It uses what's called "dual reality" i.e. what the audience thinks is happening is slightly different to what the people involved in the trick think is happening. This should not be on TED. It's not teaching anyone anything. It tells us nothing about how the human brain works. All it does is showcase Keith Barry as a magician. Which is fine, but we have magic shows for that.

I don't like that he openly lied. If he had explained it after it had happened, this TED talk would be a lot more beneficial for people.

14:00 its just a Physics

They cut the video because people watching it will notice the trick, because we are not doing it so we will not be manipulated on his trick.

Look at his left leg at 11:05....and everything will be clear how he was doing that.

the 2,392 dislikes are from Mike

So many comments about how it was done. People first appreciate the guy's effort, his performance. Don't immediately start applying ur logic & reasoning. Appreciate magic first, life is magical but by applying all sorts of silly logic & reasoning we kill the fun of life. Be it brain magic, illusion whatever. It was perfectly presented & was thoroughly entertaining!

That hand thing, he and the audience were parallel till the mid way but when he released the hold just to switch the twist of the left arm the other way as if he was guiding the audience saying things like fingers, thumbs blah blah to make audience busy with the positioning . After saying that you can see his left elbow knocked against his body(switch) which was outwards initially. Watch it carefully at 1:00 he unholded and look at this elbow which is outward and at 1:04 you can simply see the difference. Just think in reverse what he showed the so called mind blowing twist at the end.

for that first trick, thank the camera man for cutting away at the most critical point in which he switches hand positions.

this isn't a ted talk, this is a fairly ordinary stage show.

The Coke bottle was a paid actor

he just swapped glasses when he drove when she was distracted. so basically was watching the road the whole time

I did the arm cross trick at a lecture on a class of teachers and it was hilarious. They fell for it!

the "pressure" was his foot stepping on his signaling him

THREE TWO ONE AND YOUR OUT... I want you all to tell everybody else in the whole universe how amazing the show was and how amazed you were to see the amazing MAGIC..... THREE TWO ONE AND YOUR BACK

Once a magician always a magician

This was really good. He was confident, entertaining and precise at what he did! Loved the show from start to end!

"Is there any way to see through the blindfold?" "Ye-... Um.. Yes". "Okay so you CAN'T see through the blindfold, am I correct?" "No, you can see through" "Okay so you CANT see through it. Good."

Just observe Barry's leg movement & other's hand movements at 11.04 & 11.16....

To all the people screaming their pubertal, uneducated rages here, saying Keith Barry doesn't belong on TED: *TED* is an abbreviation for " Technology Entertainment & Design " Keith Barry was entertaining us, therefore he was absolutely within the guidelines. And nowhere in the title did it say *talk*. So please go and throw your tantrums elsewhere kids !

The video has a glitch at 1:01 At this point he turns his left hand 180 degrees to make that first trick work.

If you look closely at the hosts upper left leg at 11:05, you can see it rise and lower as he is giving the commands to the lady. He is using his left leg/foot to communicate to the guy when to raise and lower his arm. Oh well. Such is the world of "magic"

Impressive way to direct energies through words.

Okay so since no one seems to be noticing, here's how the "remote pressure" trick works: The magician hides his left leg behind the table. When he want the volunteer's hand to go down he presses on the volunteer's foot with his foot. And the other way around. You can see the volunteer smile the first time this happens as he has just realized what the trick is. Later, when he gets the girl to point up or down, you can see the magician's left leg lift up and down depending on what she does, as he presses on the volunteer's foot. I appreciate the simplicity of the trick

why the does the video cuts when he first obviously change the position of his hand.. to not reveal the "secret" trick? or is my computer broken?

The tricks are pretty impressive, still, I feel it was kind of a waste of time. Please do enlighten me if I'm just missing the point, but TED's profile is "Ideas worth sharing", and I see no ideas shared here, don't really feel like I learned anything.

wow the ted cameraman is part of the trick ... he actually changed his left hand around when he asked the audience to put ur right hand abv the left

"Ok we'll leave them like that (you smart man) but I'll still get the last laugh..." * proceeds to put them all flat again 🙄

As many people have also pointed out, the male volunteer was obviously a plant, and here's one other thing that proves it. Notice how, after the phone goes off, he has the male an female volunteers switch places. That's because the female had moved to the wrong position for the trick, he needed the male, who was in on it and could see what was happening, to be the one with his eye's open. Also note how during the touching trick he planted the word "tickling" in her mind, even though he probably was using wind to blow on her. The audience is obviously going to think the trick worked, so there's a disconnect between what she meant and what the audience thinks she meant when she said "tickling".

He switched his hands over when he told an imaginary person to put their thumbs the other way round

Hand touching trick: Has transparent rubber band on his hand which he uses to touch lady's hand (pulls the band on both hands at 7:44)

Anybody that is moaning that this is not a Ted talk should watch the first few minutes again...he may not have a whiteboard and sharpy ...but he explains very well what he is doing, and how he is doing it...you just have to listen.....peace.

There's a lot of suggestive signals within this man's presentation. Reverse psychology as well. However, the glass bottle part, ABSOLUTELY TRUE. It's happened to me. Not exactly in this way, but with glass melting and glass busting without me touching it.

11:00, he signals the guy with his feet. other times he doesnt shake his leg but upward he shakes it and downward he shakes the leg (signal)

09:49 I enjoyed very much this Chandler Bing and Geddy Lee crossover

What i observe Trick 1 While talking he changed his left-hand shape 1:00 Trick 2 He tapped the girl's back with his right hand 7:22 Trick 3 he uses the words 'drift and 'float back' which hit that guy's subconscious mind and follow him. Trick 4 Breaking a Coca-Cola bottle is complete chemistry. Trick 5 He taps spike wooden plinths in front of 2nd wooden plinths (while putting them in order) so the man has to choose 2nd wooden plinth because our subconscious mind chooses easy stuff and just to check if it is 2nd he moves the wooden plinths also he might have some kind symbol on spike plinths.
