ABOUT THE SPEAKER
Keith Barry - Magician
Think of Keith Barry as a hacker of the human brain -- writing routines that exploit its bugs and loopholes, and offering a revealing look at the software between our ears.

Why you should listen

As Arthur C. Clarke told us, "Any sufficiently advanced technology is indistinguishable from magic." So think of Keith Barry as a technologist, an elite software engineer of the human brain. Witty and direct, he celebrates human cleverness even while he's hacking it.

Barry's repertoire ranges from outrageous stunts -- driving a car at full speed blindfolded -- to mind control, including hypnosis and mindreading. The Irish magician's relaxed style has made him an audience favorite worldwide, both in live shows and on his European television series, Close Encounters with Keith Barry, which aired in 28 countries. He's had specials on MTV and CBS, and tried his hand at acting as a murder suspect on CSI: Miami. There are rumors of a Las Vegas residency later in 2008.

Brain magic. What's brain magic all about?

2000
00:14
Brain magic to me indicates that area of magic
1
2000
2000
00:16
dealing with psychological and mind-reading effects.
2
4000
2000
00:18
So unlike traditional magic, it uses the power of words,
3
6000
4000
00:22
linguistic deception, non-verbal communication
4
10000
3000
00:25
and various other techniques to create the illusion of a sixth sense.
5
13000
4000
00:30
Now, I'm going to show you all how easy it is
6
18000
1000
00:31
to manipulate the human mind once you know how.
7
19000
3000
00:34
And I want everybody downstairs also to join in with me and everybody here.
8
22000
3000
00:37
I want everybody to put out your hands like this for me, first of all.
9
25000
3000
00:40
OK, clap them together, once.
10
28000
2000
00:42
OK, reverse your hands.
11
30000
2000
00:44
Now, follow my actions exactly.
12
32000
2000
00:46
Now about half the audience has their left hand up. Why is that?
13
34000
3000
00:49
OK, swap them around, put your right hand up.
14
37000
3000
00:52
OK, now, cross your hands over, so your right hand goes over,
15
40000
2000
00:54
interlace your fingers like this,
16
42000
2000
00:56
then make sure your right thumb is outside your left thumb --
17
44000
2000
00:58
that's very important.
18
46000
2000
01:00
Yours is the other way around, so swap it around.
19
48000
2000
01:02
Excellent, OK. Extend your fingers like this for me.
20
50000
3000
01:05
All right. Tap them together once.
21
53000
2000
01:07
OK, now, if you did not allow me to deceive your minds,
22
55000
5000
01:12
you would all be able to do this.
23
60000
2000
01:14
(Laughter)
24
62000
6000
01:20
So, now you can see how easy it is
25
68000
2000
01:22
for me to manipulate the human mind, once you know how.
26
70000
3000
01:25
(Laughter)
27
73000
3000
01:28
Now, I remember when I was about 15,
28
76000
2000
01:30
I read a copy of Life magazine,
29
78000
3000
01:33
which detailed a story about a 75-year-old blind Russian woman
30
81000
4000
01:37
who could sense printed letters --
31
85000
2000
01:39
there's still people trying to do it here --
32
87000
2000
01:41
(Laughter)
33
89000
2000
01:43
-- who could sense printed letters and even sense colors, just by touch.
34
91000
3000
01:46
And she was completely blind.
35
94000
2000
01:48
She could also read the serial numbers on bills
36
96000
2000
01:50
when they were placed, face down, on a hard surface.
37
98000
2000
01:52
Now, I was fascinated, but at the same time, skeptical.
38
100000
4000
01:56
How could somebody read using their fingertips?
39
104000
2000
01:58
You know, if you actually think about it,
40
106000
3000
02:01
if somebody is totally blind --
41
109000
2000
02:03
a guy yesterday did a demonstration in one of the rooms,
42
111000
2000
02:05
where people had to close their eyes and they could just hear things.
43
113000
3000
02:08
And it's just a really weird thing to try and figure out.
44
116000
3000
02:11
How could somebody read using their fingertips?
45
119000
3000
02:14
Now earlier on, as part of a TV show that I have coming up on MTV,
46
122000
3000
02:17
I attempted to give a similar demonstration
47
125000
3000
02:20
of what is now known as second sight.
48
128000
2000
02:22
So, let's take a look.
49
130000
2000
02:24
(Video) Man: There we go.
50
132000
2000
02:26
I'm going to guide you into the car.
51
134000
2000
02:28
Kathryn Thomas: (Laughter)
52
136000
1000
02:29
Man: You're OK, keep on going.
53
137000
2000
02:31
KT: How are you?
54
139000
1000
02:32
Keith Barry: Kathryn, it's Keith here. I'm going to take you to a secret location, OK?
55
140000
5000
02:37
Now, Kathryn, there was no way you could see through that blindfold, at all, through all that.
56
145000
3000
02:40
KT: OK, but don't say my name like that.
57

60
152000
1000
02:45
KT: No.
61
153000
1000
02:46
KB: OK, I'm just going to take it off. You're OK, you're OK.
62
154000
1000
02:47
Do you want to take off the other part of it?
63
155000
2000
02:49
Go ahead and take it off, you're OK. We'll just stop for a second.
64
157000
2000
02:51
KT: I'm so afraid of what I'm going to see.
65
159000
2000

KB: No, no, you're fine, you're fine, take it off. You're OK. You're safe.
66
161000

02:56
Have you ever heard of second sight?
67
164000
2000
02:58
KT: No.

1000
02:59

69
167000
2000
03:01
can see through somebody else's eyes.
70
169000
3000
03:04
And I'm going to try that right now.
71

109
282000
2000
04:56
By the way, two days ago,
110
284000
1000
04:57
we were going to film this
111
285000
2000
04:59
down there, at the race course,
112
287000
1000
05:00
and we got a guy into a car,
113
288000
2000
05:02
and we got a camera man in the back,
114
290000
2000
05:04
but halfway through the drive, he told me he had a --
115
292000
2000
05:06
I think it was a nine-millimeter or something, stuck to his leg.
116
294000
2000
05:08
So, I stopped pretty quick, and that was it.
117
296000
2000
05:10
So, do you believe it's possible
118
298000
2000
05:12
to see through somebody else's eyes?
119
300000
2000
05:14
That's the question.
120
302000
1000
05:15
Now, most people here would automatically say no. OK,
121
303000
3000
05:18
but I want you to realize some facts.
122
306000
2000
05:20
I couldn't see through the blindfold.
123
308000
2000
05:22
The car was not gimmicked or tricked in any way.
124
310000
3000
05:25
The girl, I'd never met before, all right.
125
313000
3000
05:28
So, I want you to just think about it for a moment.
126
316000
2000
05:30
A lot of people try to come up
127
318000
2000
05:32
with a logical solution to what just happened, all right.
128
320000
3000
05:35
But because your brains are not trained in the art of deception,
129
323000
3000
05:38
the solutions you come up with
130
326000
2000
05:40
will, 99 percent of the time, be way off the mark.
131
328000
2000
05:42
This is because magic is all about directing attention.
132
330000
4000
05:46
If, for instance, I didn't want you to look at my right hand,
133
334000
2000
05:48
well, then, I don't look at it.
134
336000
2000
05:50
But if I wanted you to look at my right hand,
135
338000
2000
05:52
then I look at it, too. You see,
136
340000
2000
05:54
it's very, very simple, once you know how,
137
342000
2000
05:56
but very complicated in other ways.
138
344000
2000
05:58
Now, I'm going to give you some demonstrations up here, live, right now.
139
346000
2000
06:00
I need two people to help me out real quick.
140
348000
2000
06:02
Can you come up?
141
350000
1000
06:03
And let's see, down at the end, here,
142
351000
3000
06:06
can you also come up, real quick?
143
354000
1000
06:07
Do you mind?
144
355000
1000
06:08
Yes, at the end.
145
356000
1000
06:09
OK, give them a round of applause as they come up.
146
357000
2000
06:11
You might want to use the stairs, there.
147
359000
2000
06:13
(Applause)
148
361000
3000
06:16
Now, it's very important for everybody here to realize
149
364000
2000
06:18
I haven't set anything up with you guys.
150
366000
2000
06:20
You don't know what's about to happen. Is that agreed?
151
368000
1000
06:21
OK, would you mind just standing over here for a moment?
152

OK, that was a pity. I would have told them it was the ace of spades.

OK, now, I'm not hypnotizing you,

I'm merely placing you in a heightened state of synchronicity,

so our minds are along the same lines.
228
516000

at the same rate and speed
235

2000
09:06
as you drift and float into this relaxed state of awareness,
236
534000
3000
09:09

Excellent. Now that you've got the idea,

609000
2000
10:23
let's try something even more interesting.
261
611000
2000
10:25
Allow it to stick firmly to the tabletop, keep your eyes closed.
262
613000

Imagine a connection between you and him.

10:38
Only when you want the pressure to be released,
267
626000
2000
10:40
make an upward gesture, like this,
268
628000
2000
10:42

OK, let's try it again.

1000
10:56
OK, now, imagine the connection, OK.
273
644000
3000
10:59
Point directly at his forehead.

OK, it worked that time, excellent.
276
655000
2000
11:09
And hold it there, hold it there, both of you, hold it there.
277
657000

11:11
Only when you want the pressure to go back, make a downward gesture.
278
659000
3000
11:14
You can wait as long as you want.
279
662000
2000
11:18
You did it pretty quickly, but it went down, OK.
280
666000
3000
11:22
Now, I want you to be aware that in a moment,
281
670000
2000
11:24
when I snap my fingers, your eyes will open, again.
282
672000
2000
11:26
It's OK to remember to forget, or forget to remember what happened.
283
674000
3000
11:29
Most people ask you, "What the hell just happened up here?"
284
677000
3000
11:32
But it's OK that even though you're not hypnotized,
285
680000
2000
11:34
you will forget everything that happened.
286
682000

296
703000
2000
11:57
and it landed on the ground, and it didn't break?
297
705000
2000
11:59
Now, see, that's because Coke bottles are solid.
298
707000
2000
12:01
It's nearly impossible to break a Coke bottle.
299
709000

305
723000
2000

For some magicians or mentalists,
306
726000
2000
12:20
sometimes the spoon will bend or melt, sometimes it will not.
307
728000
4000
12:24
Sometimes the object will slide across the table, sometimes it will not.
308
732000
3000
12:27
It depends on how much energy you have that day,
309
735000
2000
12:29
so on and so forth.
310
737000
1000
12:30
We're going to try an experiment in psychokinesis, right now.
311
738000
2000
12:32
Come right over here, next to me.
312
740000
2000
12:34
Excellent.
313
742000
1000
12:35
Now, have a look at the Coke bottle.
314
743000
2000
12:37
Make sure it is solid, there's only one hole, and it's a normal Coke bottle.
315
745000
3000
12:40
And you can whack it against the table, if you want.
316
748000
2000
12:42
Be careful.
317
750000
2000
12:44
Even though it's solid, I'm standing away.
318
752000
2000
12:46
OK, I want you to pinch right here with two fingers and your thumb.
319
754000
3000
12:49
Excellent.
320
757000
1000
12:50
Now, I've got a shard of glass here, OK.
321
758000
2000
12:52
I want you to examine the shard of glass.
322
760000
2000
12:54
Be careful, because it is sharp. Just hold on to it for a moment.
323
762000
2000
12:56
Now, hold it out here.
324
764000
2000
12:58
I want you to imagine, right now,
325
766000
2000
13:00
a broken relationship from many years ago.
326
768000
2000
13:02
I want you to imagine all the negative energy
327
770000
3000
13:05
from that broken relationship, from that guy,
328
773000
2000
13:07
being imparted into the broken piece of glass,
329
775000
3000
13:10
which will represent him, OK.
330
778000
2000
13:12
But I want you to take this very seriously.
331
780000
2000
13:14
Stare at the glass, ignore everybody right here.
332
782000
2000
13:16
In a moment, you'll feel a certain sensation, OK,
333
784000
3000
13:19
and when you feel that sensation,
334
787000
2000
13:21
I want you to drop the piece of glass into the bottle.
335
789000
3000
13:24
Think of that guy, that ba -- that guy.
336
792000
5000
13:29
(Laughter)
337
797000
1000
13:30
I'm trying to be good here.
338
798000
1000
13:31
OK, and when you feel the sensation --
339
799000
2000
13:33
it might take a while -- drop it into the glass.
340
801000
3000
13:48
OK, drop it in.
341
816000
1000
13:50
Now, imagine all that negative energy in there.
342
818000
2000
13:52
Imagine his name and imagine him inside the glass.
343
820000
2000
13:54
And I want you to release that negative energy
344
822000
2000
13:56
by shaking it from side to side.
345
824000
2000
13:59
(Laughter)
346
827000
4000
14:03
That was a lot of negative energy, built up in there.
347
831000
2000
14:05
(Laughter)
348
833000
1000
14:06

349
834000
5000
14:11
I also want you to think of his name. Look at me and think of his name.
350
839000
2000
14:13
Have you got his name?
351
841000
1000
14:14
OK, think of how many letters in the title of his name.
352
842000
2000
14:16
Think about how many letters in the title.
353
844000
2000
14:18
There's five letters in the title.
354
846000
2000
14:20
You didn't react to that, so it's four letters in the title.
355
848000
2000
14:22
Think of one of the letters in the title.
356
850000
1000
14:23
Think of one of the letters.
357
851000
1000
14:24
There's a K in his name, there is a K.
358
852000
2000
14:26
See the way I knew that, because my name starts with a K also,
359
854000
2000
14:28
but his name doesn't start with a K, it starts with an M.
360
856000
2000

Tell Mike I said hello, the next time you see him.
361

They just, they insist that because I was a magician,
385
919000
2000
15:33
put a nice, black tablecloth on.
386
921000
2000
15:35
There you are, OK.
387
923000
2000
15:37
(Laughter)
388
925000
1000
15:38
I've got four wooden plinths here, Steve.
389
926000
2000
15:40
One, two, three and four.
390
928000
3000
15:43
Now, they're all the exact same except this one
391
931000
2000
15:45
obviously has a stainless steel spike sticking out of it.
392
933000
2000
15:47
I want you to examine it, and make sure it's solid.
393
935000
3000
15:52
Happy?
394
940000
2000
15:54
Steve Jurvetson: Mmm, yes.
395
942000
1000
15:55
KB: OK. Now, Steve, I'm going to stand in front of the table,
396
943000
4000
15:59
OK. When I stand in front of the table,
397
947000
2000
16:01
I want you to put the cups on the plinths, like this,
398
949000
2000
16:03
in any order you want, and then mix them all up,
399
951000
2000
16:05
so nobody has any idea where the spike is, all right?
400
953000
3000
16:08
SJ: No one in the audience?
401
956000
2000
16:10
KB: No one in the audience. And just to help you out,
402
958000
2000
16:12
I'll block them from view, so nobody can see what you're doing.
403
960000
2000
16:14
I'll also look away. So, go ahead and mix them up, now.
404
962000
2000
16:17
OK, and tell me when you're done.
405
965000
2000
16:19
(Laughter)
406
967000
7000
16:28
You done?
407
976000
1000
16:29
SJ: Mmm, almost.
408
977000
1000
16:30
KB: Almost, oh. OK, you're making sure that's well hidden. Now --
409
978000
3000
16:33
oh, we've got one here, we've got one here.
410
981000
6000
16:39
(Applause)
411
987000
3000
16:42
So, all right, we'll leave them like that.
412
990000
2000
16:44
(Laughter)
413
992000
2000
16:46
I'm going to have the last laugh, though.
414
994000
1000
16:47
(Laughter)
415
995000
3000
16:50
Now, Steve, you know where the spike is,
416
998000
3000
16:53
but nobody else, does? Correct?
417
1001000
2000
16:55
But I don't want you to know either, so swivel around on your chair.
418
1003000
3000
16:59
They'll keep an eye on me to make sure I don't do anything funny.
419
1007000
3000
17:02
No, stay around, OK.
420
1010000
2000
17:10
Now, Steve, look back.
421
1018000
2000
17:12
So, now you don't know where the spike is,
422
1020000
2000
17:14
and I don't know where it is either, OK.
423
1022000
2000
17:16
Now, is there any way to see through this blindfold?
424
1024000

1027000

17:25
KB: You can't see through it. Excellent, OK.
430
1033000
1000
17:26
Now, I'm going to put on the blindfold.
431
1034000
1000
17:27
Don't stack them up, OK.
432
1035000
2000
17:29
Give them an extra mix up.
433
1037000
2000
17:31
Don't move the cups, because I don't want anybody to see where the spike is,
434
1039000
2000
17:33
but give the plinths an extra mix up,
435
1041000
1000
17:34
and then line them up, like this, all right?
436
1042000
2000
17:36
I'll put the blindfold on.
437
1044000
1000

Give them an extra mix up.

1045000

No messing around this time.
439
1047000

OK, go ahead, mix them up.

ABOUT THE SPEAKER
Keith Barry - Magician
Think of Keith Barry as a hacker of the human brain -- writing routines that exploit its bugs and loopholes, and offering a revealing look at the software between our ears.

Why you should listen

As Arthur C. Clarke told us, "Any sufficiently advanced technology is indistinguishable from magic." So think of Keith Barry as a technologist, an elite software engineer of the human brain. Witty and direct, he celebrates human cleverness even while he's hacking it.

Barry's repertoire ranges from outrageous stunts -- driving a car at full speed blindfolded -- to mind control, including hypnosis and mindreading. The Irish magician's relaxed style has made him an audience favorite worldwide, both in live shows and on his European television series, Close Encounters with Keith Barry, which aired in 28 countries. He's had specials on MTV and CBS, and tried his hand at acting as a murder suspect on CSI: Miami. There are rumors of a Las Vegas residency later in 2008.
