Shadowing Practice: How to Escape Alcatraz With Basic Engineering - Learn English Speaking with Video

This is Alcatraz, the world's most famously secure prison, and today I'm going to try and escape.

This does not feel good, but I'll be doing it in a very specific way.

By recreating the exact same actions these three daring prisoners took, this is a tight squeeze,

when they executed their year -long plan in what many consider to be the most ingenious prison escape in recorded history.

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.

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,

shark -riddled waters of the San Francisco Bay I'm not sure we're gonna make it We're gonna make it!

I cannot believe they would spend 23 hours a day in this tiny little cell On June 11,

1962, at 9 .30pm, this exact jail cell would have seemed pretty unremarkable to any of the guards on duty,

and to all but three of the prisoners held here on the island.

Because that's the night those three prisoners decided they were finally

going to attempt their escape after nearly a year of meticulous planning and preparations.

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,

down to the water, and across the bay to their freedom.

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,

or a homemade raft fashioned from prison -issued raincoats.

But all six of those critical steps started right back here with the decoy, moments after lights out at 9 .35pm.

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

when guards came by to perform headcounts several times during the night.

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.

This is kind of creepy and it shows how good the heads are

because I feel like I'm in a jail cell with a sleeping man just out of the corner of my eye.

The only thing that's missing is the snoring.

Now at this point it's worth mentioning these weren't your average prisoners.

Frank Morris had an IQ of 130 and he was the mastermind who planned everything.

Then brothers John and Clarence Anglin, while not as smart as Frank, were resourceful and good with tools.

All three had previously escaped from other prisons

so they were sent to Alcatraz because no one had successfully escaped in its 28 year history.

So in order to assess

and truly appreciate every aspect of their bootleg prison engineering I

needed to recreate all the steps they took in their escape

so I assembled a prison break team of my own with Johnny Harris and Cleo Abram.

Cleo would be the mastermind and Johnny and I would be the slightly dumber pair of brothers.

Really, really good.

So we gathered up all the exact same materials they had at their disposal.

Never made a fake head before, but I think we can do it.

And began the first test.

I'm going to start mixing.

Mixing what?

When it comes to arts and crafts, it's a good idea.

It's fair to say.

I just need your face.

This team lacked experience.

This is Mark Rober with his abs.

Despite all that, I think they turned out pretty good.

These are amazing.

Because it turned out all you really needed to do was bring in your most artistic friend, Brooke.

Who's do you want to start with?

I'm going to start with, oh god.

Brooke, save us.

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,

so he provided the paint.

His brother, John, on the other hand, worked in the barbershop, so he provided the actual human hair they used.

Hello.

Is that how you see me?

Here's Mark.

Oh my god.

So with our picture -perfect facsimiles finished, we put our heads to the test with prison guard Bam.

Prisoner check.

Who had been told all three of us remained asleep in our beds.

And our outcome was significantly different than theirs.

What?

I told you, Johnny.

It almost worked.

Why are your eyes so wide open like this?

Providing early evidence, these weren't your average prisoners.

All right, next test.

Now that their diversion was set, at 9 .37 p .m., they grabbed some tools

and crawled through a hole in their jail cell wall they had spent the previous six months secretly digging out.

So this is the actual hole they crawled through to escape.

As you can see, it is not very large.

Wow, this is a very tight squeeze.

Ow!

To give themselves a head start on digging, they decided to enlarge an already existing air vent hole underneath each of their sinks.

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.

So to gain a better appreciation for what this would actually take, it was time for my jailbreak crew to get to work

on a replica prison cell we built in crunch labs using concrete

that was similar to what they would have faced my fingers are starting to get tired

and it's literally wow you're so soft

It quickly became clear why it would have taken them months

to painstakingly scrape their way to a hole big enough to escape from,

which begs the question, how do you cover up your digging progress

so the guards don't discover it during their routine room inspection?

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.

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.

One of the first things he showed me was this.

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.

From a maker standpoint, this is a masterpiece.

Yeah.

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.

Back in prison, we were making some progress, but it wasn't exactly quiet work.

Our three escapees faced this same issue and came up with a clever solution.

Every night, from 5 .30 to 7, was music hour for all the inmates.

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.

And this noise management system turned out to be pretty effective.

Oh my god, that's so loud!

The end!

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.

445

¿Qué es la Técnica de Shadowing?

Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
