Shadowing Practice: I Built a Roller Coaster In My Lab - Learn English Speaking with Video

This is the most epic birthday party ever!

It's got a jet-powered tire swing,

a custom-built roller coaster, and an indoor sledding hill with actual snow.

And I set all this up to surprise the world's most deserving kid.

Safety is for losers!

YAAAHHHHH!

And importantly, three months ago, none of this existed.

Because that's

when I reached out to a friend of mine who many consider to be the greatest engineer this world has ever known.

Oh, hey Mark.

Phineas!

I'm planning on throwing the world's greatest birthday party for this kid named Ethan.

I can explain later.

For now, I need to know if you've got any ideas.

Oh, that's a great question, Mark.

One time, Ferb and I made the world's first rocket-powered tire swing.

You'll just need a tire,

your standard Illumon parts, don't forget your high-powered rockets.

Oh, and as you can see,

as long as you don't remove this screw, you'll be fine.

You do realize that breaks,

like, seven laws of physics, right?

Well, we're working with cartoon physics,

but I trust you can figure it out.

In the meantime, I was thinking Ferb and I could take a crack at your world record-breaking elephant toothpaste experiment.

Oof, I think we both have our work cut out for us.

I'll talk to you later.

Now, I knew from personal experience,

if you can pull off a Phineas and Ferb invention in real life,

it makes for a really epic party with 15 tons of jello to spare.

But the problem here was their rocket powered tire swing leaned

very heavily on the creative boundaries of cartoon physics with estimated peak forces

that would be 35 times what a human could endure.

So as a first pass,

I just slapped two rockets with 2500 newton seconds total impulse to a single chain mounted to a tire swing

and generously gave our 180 pound crash test dummy Newton first dibs on the ride of his life.

Initiator is on!

This is to test my hypothesis why Phineas and Ferb is an animated show.

3, 2, 1!

And after the smoke cleared We lost our pants That was the most powerful de-pancing in history.

The single chain is gonna make it tough

So to keep us from immediately spinning out of control

and potentially losing all our dignity in the process We doubled the chains for more stability.

Here we go.

And this time, let it rip!

The exact same thing happened.

Oh no. He can't keep his clothes on.

I think only one of them ignited,

and a high-speed camera replay revealed that's exactly what happened.

So once we fixed the faulty ignition wire, we tried again.

Go!

Yeah!

It's gone!

Causing Newton, which I'll remind you weighs more than I do,

to launch 10 feet into the air, completing the stylish dismount.

That was definitely both that time.

His shoes are on!

That's a W!

And while the dual chain configuration did provide a lot more stability,

the slo-mo revealed there was really no way to reliably keep

the thrust vector aligned in the best direction to loop us around.

This is too squirrely, we need to go to rigid chains.

So to fix that, we swapped the two chains with two solid rods.

Igniter's hot!

3, 2, 1, GO!

SWIM!

I can't see it!

As you can see here,

the rocket forces were so high,

it ripped our entire half-ton steel swing structure out from the stakes anchoring it into the ground.

Lift off!

He's gone!

Alright, well that's a successful rocket swing.

Now we just gotta figure out how to make it slightly more safe.

So we were off to a promising start.

We just needed a little more inspiration.

Hey Mark, how's the build?

It's got a little work left,

but it's getting less lethal by the minute.

I do feel though that the party needs a little something more.

I've got it!

How about you build them a backyard roller coaster like the one we made at the beginning of summer?

Steel tracks, carts with seat belts,

and of course, be sure to add extra thermal shielding for when you re-enter the atmosphere.

Aren't you a little young to be building things that require extra thermal shielding for when they re-enter the atmosphere?

Yes.

Yes I am.

Well, good luck!

Oh, gotta go!

Herb just arrived with our star of the show!

No!

Phineas, you don't need an- Talk to you later, Mark!

Ugh, that's gonna get messy.

Now the good thing about roller coasters is unlike two story tall rocket power tire swings,

roller coasters actually exist.

So I did what any self-respecting engineer would do as a first step,

and conducted some tedious research.

Now I knew that finding the perfect Goldilocks zone for our birthday guest would be critical.

100

Not so extreme it sends him back to the hospital

101

but also not so boring it feels like watching a William Osmond video.

102

So armed with all the learnings from our tedious research,

103

we set out to build the perfect indoor roller coaster for my buddy Ethan.

104

By the way, this is Ethan.

105

And what you should know about Ethan is he was recently diagnosed with a rare

106

and severely debilitating neurological condition that left him bedridden,

107

causing him to miss most of his school year.

108

In fact, his pain and nausea was so severe,

109

he couldn't even walk from one room to another.

110

But the other thing you should know about Ethan is he's incredibly resilient.

111

And after a full year,

112

he'd recovered enough to make his way back to school.

113

And as luck would have it,

114

he not only had a birthday party coming up,

115

but he was also a massive Phineas and Ferb fan.

116

Which was perfect, because we had our first prototype of the world's greatest Phineas and Ferb indoor roller coaster ready to test.

117

Okay, ma'am, here we go!

118

What?

119

Let's go, let's go!

120

Oooh!

121

Oh no!

122

I think we're gonna have to check our calculations.

123

Yup.

124

So I called up some of my buddies who are really good at this,

125

and they introduced me to the efficiency of their calculations,

126

while I introduced them to the efficiency of a 10 second build montage.

127

And while not yet perfect,

128

we were certainly on the right track.

129

Now we just needed a few more of them.

130

Good.

131

And things were coming along great,

132

but if I was going to get approval from the world's most creative engineer,

133

it would need a little something extra.

134

So I took a closer look at their original coaster and while we definitely can't send Ethan to France,

135

we definitely could send him through a snake drop,

136

a mud bucket, and a full-on car wash.

137

Snakes on a train in three, two, one!

138

Snakes, check.

139

This build was elegant.

140

Our snakes pairing beautifully with a catapult calibrated mud bath.

141

Ah!

142

That's why we wear safety glasses.

143

Why are you smiling so much?

144

You ready?

145

Clean me off!

146

Followed by a cleansing soap scrub infused with eucalyptus oil at 40 miles an hour.

147

That ought to do it.

148

Gonna need a bit of a rinse off!

149

And finally air drying with a gentle breeze.

150

Okay!

151

Okay!

152

Clean as a whistle.

153

Oh good.

154

So now with both the roller coaster and the rocket swing pretty much ready to go,

155

I opted for a check-in.

156

Hey Mark, how's it going?

157

I mean, it's getting there,

158

but how do we really make this the best birthday party ever?

159

How about...

160

Swinter?

161

It's like summer in winter.

162

All you need is a snow cone maker and a bunch of jet-powered fans.

163

But be sure to keep your windows closed.

164

You really don't want to bring Swinter inside your house.

165

Cuneus, you pointed-headed genius, I think you're onto something.

166

Alright.

167

Oh, while I have you,

168

Ferb and I were wondering if your elephant preferred mint or bubblegum flavoring bubblegum flavoring.

169

Neither!

170

Don't you boys think you're taking this a little too literally?

171

No!

172

No we don't.

173

Alright, well see ya!

174

He hung up.

175

Snowing indoors?

176

How hard could this be?

177

Turns out a lot harder than the cartoon solution of snow cone makers and fans.

178

So I invited out an old friend to help.

179

Oh my god.

180

This is crazy.

181

This is Fletcher, and if he looks familiar to you,

182

that's because five years ago I surprised him with a special birthday party of his own,

183

where he triggered the first ever Devil's toothpaste explosion,

184

and then broke the world record for the highest elephant toothpaste experiment.

185

Now at the time, Fletcher was dealing with a very rare form of brain cancer,

186

and since so many of you have asked for an update over the years, here it is.

187

I'm five years free of any sign of disease,

188

and I'm a senior in high school that's going to college.

189

And you are almost as tall as me.

190

I'm going to say I'm still taller.

191

So I explained to him the engineering challenge of creating a non-cartoon indoor snowstorm,

192

Fletcher was all in.

193

Alright, let's do it.

194

Yeah, the problem is I don't know how.

195

I don't have- don't look at me.

196

With that uninspiring kickoff, we decided to just try some items we had lying around Crunch Laps.

197

Far than I was expecting.

198

Our first thought was grating styrofoam,

199

but it turns out that's not only dangerous Ow!

200

Just grated my finger

201

But the static electricity buildup means it would rather stick to you than the ground Next up was using

202

that water absorbing polymer you find in diapers

203

But it turns out it's not very good for making snowballs It's way too slippery I'm good And on top of that,

204

the amount of diapers required would be half a metric,

205

but ton Which all left us with only one option

206

Hold this Here we go! dumping 80,000 pounds of actual ice into a wood chute.

207

Oh!

208

I think it's gonna work!

209

God!

210

Once I came in to check things out,

211

Alright, Fletch, what do you think?

212

It didn't take long for Fletcher to let the power go to his head.

213

Oh!

214

Oh!

215

I can't!

216

Ah!

217

Mark?

218

You okay?

219

Yeah, I'm fine.

220

But this is gonna work great.

221

Now that we had a solution in hand,

222

I needed Fletcher's help on one last finishing touch.

223

Oh, it was Nathan.

224

Just kidding.

225

After which, he abruptly told me he had to go.

226

See you later.

227

What?

228

Man, this is gonna take a while.

229

A lot longer now with one person!

230

We're making snow!

231

Let's go!

232

And four hours and 40 tons of ice later,

233

all that was left was to nail the surprise.

234

Eight months of planning and work comes down to this moment.

235

There he is.

236

Oh gosh, my heart's about to beat out of my chest.

237

We had Ethan's parents tell him he was auditioning for a toy commercial

238

so he wouldn't suspect anything we laid eyes on a balloon-laden indoor roller coaster resting on two feet of freshly packed snow.

239

That's cold.

240

But I had to act fast because Ethan was catching on quick.

241

Why is there a crunch lounge?

242

Hey Ethan, what's going on pal?

243

No, no, no. I thought you might need a coat.

244

Wait, I'm so confused.

245

What is your favorite cartoon?

246

Phineas and Fur probably?

247

Have you seen the episode where they make the rocket-powered swing?

248

Yeah.

249

Have you seen the episode where they send the roller coaster to space?

250

Yeah.

251

Have you seen the episode Ethan called Swinter where they turned inside into winter?

252

Yeah.

253

This is Phineas and Ferb in real life.

254

We're throwing you a birthday party today.

255

Wha- N- H- You know what a banger party needs Ethan?

256

A birthday cake?

257

It does need a cake.

258

Let's work on a cake.

259

You know what it also needs though?

260

I feel like we should have more people here.

261

Do you have friends you'd want to invite?

262

Yeah.

263

And that was the cue to send in All of Ethan's best friends And also his loudest friends.

264

Including his little sister, which meant that he had an important decision to make.

265

Ethan, is it okay if they all hang out with us?

266

Ethan, you better say yes.

267

Five bucks.

268

I have 77 cents!

269

Okay, that goes for everyone.

270

Yeah!

271

Generous.

272

When do you guys say we start with the rocket switch?

273

Yeah!

274

But before we kick off the party,

275

I realize you're probably looking for a good way to spend your 104 days of summer vacation.

276

We'll look no further, because it's here,

277

and it's called Camp Crunch Labs.

278

Camp Crunch Labs is your key to fighting that summer brain trip with an eight-week virtual space-themed summer camp

279

that hops to each of the planets in our solar system,

280

featuring weekly videos with mega experiments that I do,

281

and super challenges that you do.

282

And the best of these weekly challenge submissions earns one of these bad boys a platinum ticket,

283

Giving you the chance to join me on my favorite planet

284

for the biggest mega experiment of them all in the final episode of the summer.

285

Oi!

286

Oi!

287

Oi!

288

Oi!

289

On top of that, usually the Crunch Labs build boxes will build a super fun toy together.

290

Learning all the juicy physics how they work comes once a month.

291

But to coincide with Space Cam Crunch Labs' weekly challenges and videos all summer long,

292

we'll ship them to you every week.

293

Let's go.

294

So if you want an eight week summer camp where you can travel the cosmos while learning to think like an engineer,

295

With an absolute zero percent chance of bug bites and poison ivy,

296

head to campcrushlabs.com to reserve one of the limited spots,

297

and I'll see you in camp.

298

Back at the party, it was time to see

299

if I'd actually accomplished turning three Phineas and Ferb cartoon marvels into real life.

300

Starting first with the rocket swing.

301

You guys want to see it go?

302

What?

303

What did that happen?

304

You might notice we swapped the rockets out for a pair of 24 volt electric turbines.

305

This provided two advantages.

306

First, we learned from testing that big rockets make a lot of smoke.

307

Hold your breath!

308

Which is not ideal for your lungs or your smoke alarm.

309

And second, if you pulse the turbines at the exact natural frequency of the swing I take my lungs!

310

Which is exactly what you naturally do when you pump your legs on a swing,

311

by the way.

312

Well, then you can add more and more energy to the swing Oh no!

313

Until it has enough Come on,

314

come on, come on, come on!

315

To clear the bar.

316

Yeah!

317

Come on, come on!

318

That's real!

319

And even with their modifications,

320

a thought suddenly occurred to me.

321

That seems really dangerous!

322

My protest fell on deaf ears.

323

Safety is for losers!

324

Yeah!

325

Seeing as he was such a tough guy all of a sudden,

326

I decided to use Ethan to get a bass line.

327

Here we go, Ethan, here we go!

328

To see how high you could swing if you just had to rely on your boring old muscles.

329

Let's go!

330

Wow!

331

And the answer was pretty much horizontal.

332

Ethan, you're kinda going high.

333

High shmai.

334

Now it was my turn to see what would happen if you added 14,000 RPMs of propulsion.

335

Okay, are you guys ready?

336

Yeah!

337

Of course, the number one rule

338

when demoing a potentially disastrous engineering build at a kid's birthday is that you definitely want to do it before you...

339

I've never done this before!

340

What do you mean you've never done this before?

341

This is my first test!

342

Has it been tested?

343

No!

344

Uh oh.

345

No!

346

Yeah!

347

Yeah!

348

Yeah!

349

Yeah!

350

Yeah!

351

And the only feeling better than pulling off a build like this,

352

is how you feel when you finally get off a build like this.

353

Oh my gosh!

354

That looks so nauseating!

355

Ethan, you're next!

356

roller coaster finale, I decided we should take a little swinter break,

357

starting with some snow cones,

358

You're ready for a snowball fight!

359

Yeah!

360

And some snowballs.

361

However unfortunately for them, certain habits Yeah!

362

Are hard to kick.

363

Oh!

364

Headshot!

365

Who's next?

366

Oh, that was- Oh, that was- Ha ha ha!

367

Eat him!

368

And then suddenly and very undeservedly I might add I wasn't over my head.

369

Wait, why is everyone aiming at me?

370

Okay, truth?

371

Who wants to go sledding?

372

Go Henry!

373

High five!

374

Ethan was really encouraging with his friends.

375

He's out late!

376

That is when he wasn't attacking.

377

Hey!

378

Go Bam!

379

After we had our filled with snowballs and sledding,

380

it was time to test out the final and most audacious Phineas and Ferb in real life engineering bill.

381

Now up the stakes, Ethan reminded me what their coaster was actually like in the show.

382

There was like snakes and like a car wash and a bunch of stuff.

383

So if this is really Phineas and Ferb right here- He'd be a triangle.

384

Oh yeah, if this was Phineas and Ferb, he'd be a triangle.

385

Fair.

386

Fair.

387

But I wasn't going to make Ethan ride solo,

388

so I had no choice but to buckle up.

389

I'm nervous!

390

Yes!

391

Ethan, are you nervous?

392

Three!

393

What?

394

Two!

395

Oh gosh!

396

One!

397

Go!

398

And while the snakes were fake, the mud was real.

399

Oh no!

400

Oh no!

401

Oh my!

402

The final step, of course,

403

was to rinse off in Science Bob's 20 mile an hour car wash...

404

Oh, no!

405

Goodbye!

406

Oh, no!

407

We're pulling to a halt in front of a massive blow dryer so we could dry off.

408

Nice and clean?

409

Yeah.

410

Yes.

411

You won't have to shower tonight at least.

412

I doubt that, but um...

413

So now that all three of our inventions were tested and Ethan approved...

414

Thank you.

415

So it's time to give Ethan a well-deserved 15 second party montage.

416

Ethan, I also have a confession.

417

I didn't pull this off on my own,

418

I had a little help.

419

What do you mean?

420

Hey Phineas!

421

Look what we did!

422

Whoa!

423

You know, for not relying on cartoon physics, that looks so fun!

424

I'm happy it all worked out for you.

425

Now for the elephant toothpaste experiment!

426

Whoa, make sure Ferb isn't too close!

427

Whoops.

428

Wow, it looks like you got a lot of cleanup on your hand.

429

You want us to help?

430

Actually, our cleanup usually takes care of itself.

431

See?

432

No muss, no fuss.

433

Bye, Mark.

434

Sorry Ethan, but that trick will not work in real life.

435

Am I cleaning up?

436

Grab a shovel and let's clean this up.

437

Oh my legs!

438

Oh my god.

439

Now that Ethan's been given the best birthday ever,

440

why not join us for the best summer ever with Space Camp Crunchlots.

441

The 8 week virtual space themed summer camp designed to help fight that summer brain drain.

442

So check out campcrunchlots.com with your parents and reserve one of the limited spots,

443

and I'll see you at camp.

444

Thank you.

Wat is de Shadowing-techniek?

Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
