Shadowing Practice: I Built a Roller Coaster In My Lab - Learn English Speaking with Video
Creando lección...
1
This is the most epic birthday party ever!
2
It's got a jet-powered tire swing,
3
a custom-built roller coaster, and an indoor sledding hill with actual snow.
4
And I set all this up to surprise the world's most deserving kid.
5
Safety is for losers!
6
YAAAHHHHH!
7
And importantly, three months ago, none of this existed.
8
Because that's
9
when I reached out to a friend of mine who many consider to be the greatest engineer this world has ever known.
10
Oh, hey Mark.
11
Phineas!
12
I'm planning on throwing the world's greatest birthday party for this kid named Ethan.
13
I can explain later.
14
For now, I need to know if you've got any ideas.
15
Oh, that's a great question, Mark.
16
One time, Ferb and I made the world's first rocket-powered tire swing.
17
You'll just need a tire,
18
your standard Illumon parts, don't forget your high-powered rockets.
19
Oh, and as you can see,
20
as long as you don't remove this screw, you'll be fine.
21
You do realize that breaks,
22
like, seven laws of physics, right?
23
Well, we're working with cartoon physics,
24
but I trust you can figure it out.
25
In the meantime, I was thinking Ferb and I could take a crack at your world record-breaking elephant toothpaste experiment.
26
Oof, I think we both have our work cut out for us.
27
I'll talk to you later.
28
Now, I knew from personal experience,
29
if you can pull off a Phineas and Ferb invention in real life,
30
it makes for a really epic party with 15 tons of jello to spare.
31
But the problem here was their rocket powered tire swing leaned
32
very heavily on the creative boundaries of cartoon physics with estimated peak forces
33
that would be 35 times what a human could endure.
34
So as a first pass,
35
I just slapped two rockets with 2500 newton seconds total impulse to a single chain mounted to a tire swing
36
and generously gave our 180 pound crash test dummy Newton first dibs on the ride of his life.
37
Initiator is on!
38
This is to test my hypothesis why Phineas and Ferb is an animated show.
39
3, 2, 1!
40
And after the smoke cleared We lost our pants That was the most powerful de-pancing in history.
41
The single chain is gonna make it tough
42
So to keep us from immediately spinning out of control
43
and potentially losing all our dignity in the process We doubled the chains for more stability.
44
Here we go.
45
And this time, let it rip!
46
The exact same thing happened.
47
Oh no. He can't keep his clothes on.
48
I think only one of them ignited,
49
and a high-speed camera replay revealed that's exactly what happened.
50
So once we fixed the faulty ignition wire, we tried again.
51
Go!
52
Yeah!
53
It's gone!
54
Causing Newton, which I'll remind you weighs more than I do,
55
to launch 10 feet into the air, completing the stylish dismount.
56
That was definitely both that time.
57
His shoes are on!
58
That's a W!
59
And while the dual chain configuration did provide a lot more stability,
60
the slo-mo revealed there was really no way to reliably keep
61
the thrust vector aligned in the best direction to loop us around.
62
This is too squirrely, we need to go to rigid chains.
63
So to fix that, we swapped the two chains with two solid rods.
64
Igniter's hot!
65
3, 2, 1, GO!
66
SWIM!
67
I can't see it!
68
As you can see here,
69
the rocket forces were so high,
70
it ripped our entire half-ton steel swing structure out from the stakes anchoring it into the ground.
71
Lift off!
72
He's gone!
73
He's gone!
74
Alright, well that's a successful rocket swing.
75
Now we just gotta figure out how to make it slightly more safe.
76
So we were off to a promising start.
77
We just needed a little more inspiration.
78
Hey Mark, how's the build?
79
It's got a little work left,
80
but it's getting less lethal by the minute.
81
I do feel though that the party needs a little something more.
82
I've got it!
83
How about you build them a backyard roller coaster like the one we made at the beginning of summer?
84
Steel tracks, carts with seat belts,
85
and of course, be sure to add extra thermal shielding for when you re-enter the atmosphere.
86
Aren't you a little young to be building things that require extra thermal shielding for when they re-enter the atmosphere?
87
Yes.
88
Yes I am.
89
Well, good luck!
90
Oh, gotta go!
91
Herb just arrived with our star of the show!
92
No!
93
Phineas, you don't need an- Talk to you later, Mark!
94
Ugh, that's gonna get messy.
95
Now the good thing about roller coasters is unlike two story tall rocket power tire swings,
96
roller coasters actually exist.
97
So I did what any self-respecting engineer would do as a first step,
98
and conducted some tedious research.
99
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.

¿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.
