1
This is Alcatraz, the world's most famously secure prison, and today I'm going to try and escape.
2
This does not feel good, but I'll be doing it in a very specific way.
3
By recreating the exact same actions these three daring prisoners took, this is a tight squeeze,
4
when they executed their year -long plan in what many consider to be the most ingenious prison escape in recorded history.
5
So to pull this off, they gave me unrestricted access to the whole prison, because our goal is to use modern technology along with our own engineering skills.
6
There's driven once and for all whether these three escapees actually made it safely to land Guys, we are no longer in a row Or if they vanished forever in the frigid,
7
shark -riddled waters of the San Francisco Bay I'm not sure we're gonna make it We're gonna make it!
8
I cannot believe they would spend 23 hours a day in this tiny little cell On June 11,
9
1962, at 9 .30pm, this exact jail cell would have seemed pretty unremarkable to any of the guards on duty,
10
and to all but three of the prisoners held here on the island.
11
Because that's the night those three prisoners decided they were finally
12
going to attempt their escape after nearly a year of meticulous planning and preparations.
13
But in order to pull this off, starting right here in their cells, they would need to execute their elaborate six -part escape plan flawlessly, eventually taking them up and out of the prison,
14
down to the water, and across the bay to their freedom.
15
And to pull this off would require countless strokes of genius, like fake vents to cover up their digging progress, fake bolts made from sculpted soap,
16
or a homemade raft fashioned from prison -issued raincoats.
17
But all six of those critical steps started right back here with the decoy, moments after lights out at 9 .35pm.
18
Since they weren't expected out of bed until roll call the next morning, they needed a way to not sound the alarms with empty beds
19
when guards came by to perform headcounts several times during the night.
20
So they placed fake heads like these on their pillows that they had spent two months crafting out of soap, concrete dust, toothpaste, toilet paper, and actual human hair.
21
This is kind of creepy and it shows how good the heads are
22
because I feel like I'm in a jail cell with a sleeping man just out of the corner of my eye.
23
The only thing that's missing is the snoring.
24
Now at this point it's worth mentioning these weren't your average prisoners.
25
Frank Morris had an IQ of 130 and he was the mastermind who planned everything.
26
Then brothers John and Clarence Anglin, while not as smart as Frank, were resourceful and good with tools.
27
All three had previously escaped from other prisons
28
so they were sent to Alcatraz because no one had successfully escaped in its 28 year history.
29
So in order to assess
30
and truly appreciate every aspect of their bootleg prison engineering I
31
needed to recreate all the steps they took in their escape
32
so I assembled a prison break team of my own with Johnny Harris and Cleo Abram.
33
Cleo would be the mastermind and Johnny and I would be the slightly dumber pair of brothers.
34
Really, really good.
35
So we gathered up all the exact same materials they had at their disposal.
36
Never made a fake head before, but I think we can do it.
37
And began the first test.
38
I'm going to start mixing.
39
Mixing what?
40
When it comes to arts and crafts, it's a good idea.
41
It's fair to say.
42
I just need your face.
43
This team lacked experience.
44
This is Mark Rober with his abs.
45
Despite all that, I think they turned out pretty good.
46
These are amazing.
47
Because it turned out all you really needed to do was bring in your most artistic friend, Brooke.
48
Who's do you want to start with?
49
I'm going to start with, oh god.
50
Brooke, save us.
51
And having Brooke to help us actually put us on par with the original escapees, because they had their own resident artist in one of the brothers, Clarence England, who also worked maintenance and painted as a hobby,
52
so he provided the paint.
53
His brother, John, on the other hand, worked in the barbershop, so he provided the actual human hair they used.
54
Hello.
55
Is that how you see me?
56
Here's Mark.
57
Oh my god.
58
So with our picture -perfect facsimiles finished, we put our heads to the test with prison guard Bam.
59
Prisoner check.
60
Who had been told all three of us remained asleep in our beds.
61
And our outcome was significantly different than theirs.
62
What?
63
I told you, Johnny.
64
It almost worked.
65
Why are your eyes so wide open like this?
66
Providing early evidence, these weren't your average prisoners.
67
All right, next test.
68
Now that their diversion was set, at 9 .37 p .m., they grabbed some tools
69
and crawled through a hole in their jail cell wall they had spent the previous six months secretly digging out.
70
So this is the actual hole they crawled through to escape.
71
As you can see, it is not very large.
72
Wow, this is a very tight squeeze.
73
Ow!
74
To give themselves a head start on digging, they decided to enlarge an already existing air vent hole underneath each of their sinks.
75
And since they obviously didn't have access to power tools, they had to get creative, primarily using stolen spoons from the cafeteria that they'd fashioned into picks by removing the round parts.
76
So to gain a better appreciation for what this would actually take, it was time for my jailbreak crew to get to work
77
on a replica prison cell we built in crunch labs using concrete
78
that was similar to what they would have faced my fingers are starting to get tired
79
and it's literally wow you're so soft
80
It quickly became clear why it would have taken them months
81
to painstakingly scrape their way to a hole big enough to escape from,
82
which begs the question, how do you cover up your digging progress
83
so the guards don't discover it during their routine room inspection?
84
So to answer that question, I headed to the prison archives to meet a good friend of mine, Adam Savage, because he has a lot of myth -busting knowledge on this topic.
85
We didn't know that there were still pieces of the original thing until we called over here, and they're like, yeah, come on down, we can show them to you.
86
One of the first things he showed me was this.
87
Basically, they created an incredibly realistic vent cover made from just cardboard, notebook covers, and soap, which they then painted prison green using spare paint they stole from a maintenance shed.
88
From a maker standpoint, this is a masterpiece.
89
Yeah.
90
To make this out of, like, homegrown materials you're scabbing from the prison shop, and to have looked this good, like a concrete wall, is incredible.
91
Back in prison, we were making some progress, but it wasn't exactly quiet work.
92
Our three escapees faced this same issue and came up with a clever solution.
93
Every night, from 5 .30 to 7, was music hour for all the inmates.
94
So one of them would loudly play an accordion while one kept watch for guards with a makeshift periscope, and the third one scraped away.
95
And this noise management system turned out to be pretty effective.
96
Oh my god, that's so loud!
97
The end!
98
The end!
99
our efforts were proving that digging through concrete with headless spoon was very slow work
100
and this must have been something frank morris the mastermind concluded as well
101
because he ended up getting his hands on an old vacuum used for maintenance exactly like the model shown here
102
and then if you pop off the top shell
103
and then remove the fan assembly you will find we have a modified power drill.
104
And that ought to speed things up a little bit.
105
All the inmates had power outlets in their cells that allowed them to use things like electric shavers, or in this case, bootleg engineered power drills.
106
So with the accordion once again masking the sound, they resorted to an improved method of drilling a series of holes
107
and then using the spoons to remove the remaining excess material between the holes.
108
And as much as this did increase our output as well it was clear this would still take weeks
109
and i wanted to get to the crawl through test
110
so i raised the white flag and resorted to an air hammer
111
which they definitely didn't have at their disposal until the hole
112
was the exact same size as the holes in their cells
113
look at how much like concrete they would have had to
114
remove from the premises right put it in their pockets put it out in the yard yeah
115
but this is the actual size of the hole they escaped from I can smell the freedom.
116
So it turns out they were like 135 pounds.
117
These are tiny dudes.
118
They're tiny dudes.
119
I don't know if my head will fit through here.
120
Cat goes first.
121
Now I have to make it.
122
Oh crap.
123
Oh, there's no way.
124
Let's push him.
125
Oh.
126
No, there's no way this guy's gotten through.
127
All that work.
128
Ow.
129
Johnny makes things up with the feet first approach.
130
which meant it all came down to cleo i can totally
131
do this oh my god she's doing it oh my gosh she's doing it i can do this
132
cleo bro she's already gone wow okay okay well you want a game of tic -tac -toe i guess Okay.
133
Back to our prisoners.
134
With step two out of the way, at 9 .48 p .m., they found themselves in sort of a secret passageway between the cells.
135
But the problem was, they'd have to silently make their way to step three that was four stories above them.
136
Here's the holes they would crawl out right here into this utility corner, which honestly is pretty spacious.
137
But more importantly, they had to make it to the loft, and there's all these pipes that basically act as ladders that lead them all the way up to right here.
138
This is wild.
139
This was the roof of the cell block, but when they got here that night, there was already a homemade life raft and life vests, homemade paddles, and makeshift flashlights waiting for them.
140
And that's because this wasn't their first time up here.
141
They had been sneaking up here for months, using the same decoy heads and fake vent covers, bringing up their hidden homemade tools every night as they fabricated their means for escape.
142
And they knew about this spot
143
because one of them was actually assigned to work up here for a couple hours during the day,
144
painting the ceiling and doing general maintenance under the watchful eyes of the guards patrolling right across the hall.
145
So they devised a plan, and every day he would sweep dust down onto the polished floors below, and when the guards and other prisoners eventually complained about the mess, he proposed a simple solution.
146
Hanging up blankets in these locations to stop the dust from falling down, creating themselves a private little workshop in the process.
147
So of course, once they hang out the blankets, that means they could work up here undetected for months coming up every night, doing some work, crawling down in the morning.
148
Frank Morris, the mastermind.
149
She's an absolute genius.
150
And of course, it makes sense then why during the day they'd work as slowly as possible, taking months to not even finish painting the whole ceiling.
151
Oh, this is cool.
152
So you could literally see how far he made it over just to buy themselves more time.
153
Frank worked in the library, which gave him access to reading materials like Popular Mechanics, where he learned some of the skills they used for designing their paddles
154
and constructing the raft and life preservers made from over 50 army -issued raincoats they had borrowed or stole from other inmates.
155
And bear in mind, these weren't exactly ideal working munitions.
156
Any noise they make up here just echoes throughout the entire prison.
157
On top of that, this is where the guards would patrol back
158
and forth with Thompson sub -machine guns keeping an eye on all the prisoners.
159
So it's wild that just 15 feet away, these guys were literally fabricating their means for escape.
160
And now that they had completed step three and were ready to head to the roof with all their provisions, it was our turn to do the same by building the actual rafts we would use to make our own escape.
161
So now we're up to the loft.
162
We're out of our cells.
163
The next big step is how do you make it through these frigid, shark -infested waters?
164
What's cool is they had these popular mechanics magazines.
165
Inside was how to make a homemade life preserver.
166
No way.
167
Literally, your life preserver, how will it behave if you need it?
168
This is the one I feel like is the most nonsensical.
169
It's such a refined construction of a life vest.
170
I feel like this is them showing off.
171
This is absolutely them showing off.
172
It's like get a piece of foam in like a milk jug.
173
You know, it's doing the same thing.
174
Is this a raft?
175
Our theory was that they made four tubes
176
and then realized we don't need the second short one because we can just make it a long triangle.
177
These tubes are something like 14 feet?
178
Yeah.
179
That's a yacht.
180
Now those instructions were applicable for the typical material you'd find in a rain jacket.
181
So these guys collected like 56 of them.
182
They made life preservers in a raft, which we are about to do.
183
These are some smart dudes.
184
MacGyver on steroids.
185
Here we go.
186
We found a roll of rubberized canvas
187
that matched the material of the prison issue rain jackets and then cut them into rain jacket size strips.
188
Oh yeah.
189
Wow, that's satisfying flow.
190
Wow.
191
Oh, that was so unsatisfying.
192
And then we used period accurate rubber cement to glue the segments together with two and a half inch seams.
193
Our life depends on these seams.
194
If one of these even has a little leak.
195
Oh, my applicator already broke.
196
Are there more applicators?
197
And then fully sealed the deal with some hammer time.
198
And if this seems insanely loud, don't worry.
199
I'm going to cover it up.
200
We brought the accord.
201
The guards will have no idea what we're doing.
202
And with that, we rolled it onto itself, then sealed the ends, which led to the final test.
203
Seeing if we could inflate it using the same secret weapon the escapees had.
204
Oh, yes.
205
They took an accordion and actually used it as an air pump.
206
Yeah.
207
There you go.
208
It's pretty strong.
209
See?
210
Okay.
211
The fate of our survival rests on this moment.
212
This is the actual raft we will be using to cross the shark -infested Alcatraz waters.
213
Here we go.
214
Oh my God, it's working.
215
It's working.
216
Keep going.
217
And over the course of about 37 squeaky pumps, we had a fully inflated raft.
218
The accordion is the unsung hero.
219
Or I guess it's sung.
220
A little bit sung.
221
Yeah.
222
But the all -important question was...
223
Listen for a leak.
224
Is it fully airtight?
225
Nothing.
226
Cleo's overjoyed response made it clear that if we just repeated that exact same thing two more times, we'd have a fully functioning wrath.
227
Next for the inmates was making it onto the roof.
228
But before they do that, it's worth looking at their tools and appreciating that while they didn't have college degrees, they certainly thought like engineers because they were resilient problem solvers.
229
And to me, this is what it means to think like an engineer.
230
And this is such an important skill to develop for life.
231
It's written right on the side of every Crunch Lab's build box that gets delivered to your door every month, where we build a really fun toy together and then learn all about the fascinating physics that makes them work.
232
But the best part is, just like I do with my YouTube videos, we hide the vegetables.
233
So you're learning all these useful life skills like resilience, but every step of the journey is really fun.
234
On top of that, each month your box has a chance to contain the platinum ticket.
235
And if you get it, then you're coming out to Crunch Labs to build with me and my team for a day.
236
So if you're a kid looking for something to put at the top of your Christmas list, or you're just looking to be the household hero by giving it to someone else,
237
head to CrunchLabs .com where we're giving away two free boxes for our holiday special, and where you'll find we've finally completed our trilogy of creative engineering subscription box options,
238
now ranging from ages 6 to 106.
239
Back with our escapees at 10 45 p .m.
240
They were now at step four of their escape plan ready
241
to head to the roof through this vent This right here
242
is the vent they did it through Now they had previously sawed through the bolt that held the vent shut, and then replaced it with a fake bolt made of soap they had painted to look real.
243
They had also previously bent away a restriction bar intended to
244
keep a human from fitting through the ventilation pipe using an
245
ingenious homemade bar spreader consisting of two opposite threaded bolts with a threaded turnbuckle in the middle.
246
So when they tightened the turnbuckle with their homemade wrench, the two bolt heads would slowly deform their restriction bar until there was room enough to slip through.
247
So they busted through, pushed up the metal vent, pushed out their rafts, and crawled to the roof at the potential freedom.
248
We know the exact time they got on the roof because a guard and several inmates reported hearing a loud bang.
249
If you had to push this thing over, it landed on the roof, that's going to make a lot of noise.
250
That's loud.
251
You can just imagine, they've made it up on the roof.
252
They've got their rafts.
253
They're running to the edge.
254
They've got the city of San Francisco behind them.
255
Golden Gate Bridge to their left
256
and they know they are mere hours away from drowning in these frigid waters for total freedom.
257
It's one or the other.
258
So they came here to the edge of the roof, then climbed down the water pipe, made their way along the exercise yard, down by the water tower, and around the power station.
259
Now what's truly remarkable about
260
that route is they'd have to scale two separate 12 -foot barbed wire fences with all their gear in tow
261
while going undetected by the armed guards on the search towers
262
who were ordered to shoot on sight any prisoner attempting to escape.
263
And the final part of the escape, conveniently, where you can't be seen by the guard tower, they made their way down this embankment and entered the water right here.
264
Now this beach wasn't the easiest spot for them to access, but mastermind Frank chose it specifically because it was in a blind spot for all the guard tower searchlights.
265
So now that they were down by the water's edge, they inflated the rafts using the modified accordion they turned into an air pump and set off to Angel Island.
266
So to get a sense of whether this would even be remotely possible in a homemade raft, We launched our own homemade raft from a beach location that was very similar to theirs.
267
Go, go, go, go, go.
268
Careful, careful.
269
I don't want you to break it.
270
This is it, guys.
271
This has to work.
272
Okay.
273
Time to start making the music.
274
Get in there.
275
I'll hold you, pump.
276
Johnny, why don't you start filling one in the other's with your mouth?
277
Okay.
278
Can you imagine being here on the beach?
279
Being like, the guards might come at any moment.
280
Blow harder, Johnny.
281
Come on, Johnny.
282
This is not easy.
283
Tastes like glue.
284
No, damn it.
285
Oh, no. I didn't prepare for this.
286
Let's get these on.
287
Watch your eyes.
288
Oh, shoot.
289
It just broke.
290
It still works.
291
Getting a core workout here.
292
Guys, I'm almost full.
293
This one's full.
294
No way this lasts.
295
This is the first thing I'm doing.
296
All right, we've got to get in the water.
297
Let's get in the water.
298
Go, go, go, go.
299
Get in there.
300
Oh, it's cold.
301
Get in, Cleo.
302
Careful on those seams.
303
It's solid.
304
Let's go, Rick.
305
We're free.
306
We're free.
307
We're free.
308
now you'll notice it's not exactly dark even though we know they launched after lights out in the evening that's
309
because we ran some tests of our own by strapping 20 gps devices in waterproof containers to some driftwood
310
and then we threw them in the water near their launch spot at various times in the tide cycle
311
and then we tracked where they ended up
312
and this experiment yielded some very unexpected results whoa we're looking
313
at some movement here wait this is not what i was
314
expecting to see we're trying to go over here not now
315
because of the strong current the driftwood logs got caught up in, none of them even came close to making it to their intended destination Angel Island,
316
either as the current came in on high tide or went out on low tide.
317
In fact, of all the logs we threw in, only a few ever made it to land during an ideal
318
30 minute tidal window at a location right about here next to the Golden Gate Bridge.
319
And this is something Frank probably knew as well by observing debris in the water moving with the tides, meaning all their rumored plans for heading to Angel Island were just diversions
320
and their real plan was to land here all along
321
so to maximize our chance of a successful escape we entered
322
the water at the same perfect 30 -minute tidal window based
323
on the tides for our day for paddling to freedom folks
324
the tide is just pulling us let's go we're moving
325
so fast man guys this is epic look at this look at
326
this is beautiful we're free oh my god wow this is amazing
327
we were feeling optimistic
328
but once we got about a quarter of the way to
329
the bridge the waves drastically increased in size oh these waves are huge oh my way oh i was getting queasy fast.
330
So I ditched the paddle and adopted a new strategy.
331
Okay, at this point, you live and die by the current.
332
Paddling is just totally free trial.
333
It's just about surviving and like floating our way in the current.
334
A large portion of my body is underwater right now.
335
I'm just like engulfed this thing.
336
I cannot move.
337
We're basically sitting in just a massive life preserver.
338
Like the world's most dangerous water vent.
339
With like sharks swimming around you.
340
And this was a Legitimate concern.
341
Here's an actual clip right off the shore of Alcatraz of a great white shark hunting a seal.
342
In fact, when I was scouting out the location the inmates launched their raft, I saw another seal right off the shore.
343
You know what these seals?
344
Sharks.
345
To make matters worse, I knew in this area great whites hunted primarily at dawn and dusk.
346
It gives you some real appreciation for what and how they did this.
347
How do you think they were feeling if they got this far?
348
Victorious.
349
This not home free yet.
350
Big waves!
351
Oh my goodness!
352
These are six footers!
353
He's a white cat!
354
Literal white cat!
355
Oh my god!
356
We're almost cap time!
357
It is tumultuous on the open sea.
358
And despite the rough waters, our great escape was going pretty well, right up until the raft started deflating.
359
We're definitely losing air!
360
This is not good.
361
The moment I put a little bit of pressure on it, air comes rushing out.
362
I'm holding on tight right here, making sure it doesn't leak.
363
And I'm holding this one on this side
364
and since our trusty accordion pump was back on shore we
365
had to get creative get some air back in there please folks our survival depends on it
366
and to make matters worse water everywhere in here this is more than
367
that time dude we are up to our waist in water the waves are just
368
so hot the water is freezing cold but alcatraz is fading into the distance
369
and the golden gate bridge is coming closer and this was good news
370
because even if johnny made it it was looking more
371
and more likely his dinner wouldn't i'm nauseous you better be battling
372
oh god it might vomit sorry okay i'm probably to the
373
end i will not be defeated i will not be defeated oh this is for freedom Go, Cleo!
374
Go, Cleo!
375
We are sinking so much faster.
376
But you know what?
377
You've got heart.
378
And if you've got heart, you've got freedom.
379
That's not actually true.
380
We are really putting on a lot of water.
381
That is actually true.
382
We can do this, guys.
383
We can do this.
384
Guys, the bridge is right there.
385
I see the bridge.
386
Dr. Trans is fading with every minute.
387
Guys, we are no longer in a raft.
388
This is the ocean.
389
We are going outside, um, Johnny?
390
I'm up to my sternum now.
391
I'm like most underwater.
392
No, I'm not.
393
Are you okay?
394
Are you okay?
395
No, we don't.
396
Stay with us.
397
Stay with us.
398
Johnny looked like he had a plan to fix our sinking situation, but it turns out he was thinking more about content than survival.
399
We're back together again.
400
Which makes this a good time to mention no matter what happens here, you should know they both have incredible YouTube channels.
401
Like Cleo just uploaded a video about what we could actually do if a giant asteroid were headed towards Earth.
402
An asteroid impact is worse than you might think.
403
And Johnny just uploaded a video about the infamous El Chapo prison escape in Mexico.
404
This place was considered inescapable.
405
But even still, he had escaped through one of his tunnels. So close!
406
The current's taking us!
407
It still has air!
408
Hold on to that!
409
Hold on!
410
I am!
411
The current had done about 90 % of the work for us, and now it was up to us to make the final push to freedom.
412
Big push!
413
Go!
414
Big push!
415
Come on.
416
Which would have been much easier without my prison -issued footwear.
417
Are you still coping?
418
Stop!
419
Oh my God.
420
Come on, we're there.
421
We're free.
422
Oh my God.
423
Land, land!
424
Oh my God.
425
We made it!
426
We did it!
427
We did it!
428
We actually did it!
429
We turned from all the trash!
430
Oh!
431
We actually did it.
432
We're free.
433
Oh my God, I'm so tired right now.
434
That's one of the hardest things I've ever done in my whole life.
435
Yeah.
436
So after all that, the question that remains is did they survive that final step?
437
Now what we know for sure is the FBI recovered evidence of their escape, like paddles or life jackets, in these four locations.
438
But what we also know is on any given night, there's only a 30 minute window where the high tide current will take you from Alcatraz safely to land.
439
And any attempt outside that time frame basically means certain death from hypothermia or drowning.
440
And thanks to a lot of modern science, we, of course, knew exactly when that 30 -minute window was for our escape.
441
And so after checking the historic tide records on the exact night of their escape, for them, that vital window would be between 11 .30 and midnight.
442
And according to the FBI records, ingenious Frank Morris, with access to none of the data we had, pushed off right in that sweet spot at 11 .40 p .m.
443
Even with all that, realistically, I still put their odds at less than a 50 % chance of surviving the final step.
444
But if anyone was going to beat those odds, it would be the serial escape artist, genius IQ, bonafide bootleg prison engineer, Frank Morris.

القواعد في هذا الفيديو
أكثر التراكيب التي يستخدمها المتحدث، مع العبارات نفسها من الفيديو:
| التركيب | في الفيديو |
|---|---|
| الجمل الشرطية if + جملة، will/would + فعل — شرط ونتيجته | if my head will fit |
| المبني للمجهول be + اسم المفعول — التركيز على ما يحدث لا على من يفعله | weren't expected · were sent · had been told |
| المضارع التام have/has + اسم المفعول — حدث ماضٍ ما زال له أثر الآن | we've finally completed · they've made · I've ever done |
نطق يحتاج إلى انتباه
يستخدم المتحدث 107 من الصيغ المختصرة، مثل we're, I'm, gonna. انطقها بصيغتها القصيرة كما تسمعها.
- أصوات “th”: thread /ˈθɹɛd/, theirs /ðɛɚz/, gather /ˈɡæðɚ/, myth /mɪθ/, underneath /ˌʌndɚˈniθ/
- أصوات “sh” و“zh”: ventilation /ˌvɛntɪˈleɪʃ(ə)n/, shore /ʃɔɹ/, appreciation /əˌpɹiː.ʃiˈeɪ.ʃən/, gosh /ɡɑːʃ/, restriction /ɹɪˈstɹɪkʃən/
- الكلمات الطويلة — انتبه لموضع النبر: ventilation /ˌvɛntɪˈleɪʃ(ə)n/, primarily /ˈpɹaɪ.mə.ɹə.li/, appreciation /əˌpɹiː.ʃiˈeɪ.ʃən/, underwater /ʌndɚˈwɔtəɹ/, resilience /ɹɪˈzɪl.ɪ.əns/
أصوات يجدها متحدثو العربية صعبة:
- /p/ — ليس /b/: انطقه مع نفخة هواء: prisoner /ˈpɹɪzənə/, pump /pʌmp/, soap /soʊp/, primarily /ˈpɹaɪ.mə.ɹə.li/, pipe /ˈpaɪp/
- /v/ — ليس /f/: مع اهتزاز الأوتار الصوتية: ventilation /ˌvɛntɪˈleɪʃ(ə)n/, survival /sɚˈvaɪ.vəl/, discover /dɪˈskʌvə/, vital /ˈvaɪtəl/, recover /ɹɪˈkʌvɚ/
- تتابع الصوامت — لا تضف حركة بينها: prisoner /ˈpɹɪzənə/, concrete /ˌkɑnˈkɹit/, bolt /boʊlt/, crawl /kɹɔːl/, pump /pʌmp/
كيف تتدرب بهذا الفيديو
- استمع إلى الفيديو كاملًا مرة واحدة دون أن تتكلم، ودوّن الكلمات التي لا تعرفها.
- ابدأ بسرعة 0.75×، وردّد جملة جملة، ثم عُد إلى السرعة العادية عندما يصبح الأمر سهلًا.
- سجّل صوتك وقارنه بالأصل، مع الانتباه إلى كلمات مثل prisoner, homemade, ventilation.
ما هي تقنية التظليل الصوتي؟
التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
