Shadowing Practice: Last Cheater Standing Wins $10,000! - Learn English Speaking with Video

I invited all the internet's smartest creators to compete for $10,000 in the first ever - Cheat the Casino Games, - where they'll go head to head in all the classic casino games with the catch that they could cheat using clever engineering, as long as they didn't get caught.

- You... filthy... cheat!

- And while I knew I'd be surrounded by ingenious rule breakers, what I never suspected was that one of the cheaters would spend a month preparing the ultimate engineering double cross, undermining the entire competition and turning the whole night on its head.

- Who stole the money?

Hey everyone, welcome to the first annual CrunchLabs Cheat the Casino Games.

Science Bob Pflugfelder, he's my pit boss.

Also have Bam from CrunchLabs, head of security.

Now, something none of you knew is that whoever gets the most chips tonight will be earning for the charity of their choice, $10,000 in cash.

You're probably wondering where the cash is.

So am I, Science Bob.

That was supposed to be a dramatic reveal.

- Sorry, sorry, I wanted more of like a walk-in.

Bring it in, guys!

- OK, here it is.

Thank you, security.

I had the internet's most trusted science teacher here yesterday to verify this was real cash.

Hank Green, is that right?

- A hundred percent!

- Tonight, you should just know there are two rules and two rules only.

- Number one, you can use whatever engineering device you made to cheat, but if I find it, then I'll confiscate it and you have to play fair.

- And number two, you'll be forbidden to enter and permanently banned if you are Michael Reeves.

I'm sorry, Michael.

- No, he's kidding. It's a joke, right?

- I don't know what you were planning, but I know it's way too unhinged for my channel.

- Curse you, Mark! Curse you and your abs!

- I don't make the rules, Michael.

- Your juicy, juicy abs, Mark.

Your name is Mark Rober.

I hate you forever.

- Let the games begin!

- This was easily the biggest party CrunchLabs had ever seen.

- Science Bob.

- Welcome to your party.

- Wow, there's a lot of people in here.

- With my many friends in the science and tech YouTube space here to enjoy four classic casino games, poker, blackjack, craps, and roulette.

And out of the gate, the blackjack table, - Hey everyone.

- piqued my suspicion.

- How are we doing?

- To begin my hunt for a cheater, I was looking for strong hands, odd behavior, and winning streaks.

- Oh, look at that, how'd you do that?

- Anything unusual could be a sign of foul play, and fortunately, - Mark!

- I wasn't working alone.

- Come check this out.

- Bam caught something through our complex system of 62 cameras and computer vision algorithms, which I affectionately call the Michael Reeves AI Face Detection Defense System, where 95% of the compute power is dedicated to making sure Michael Reeves could not sneak back in.

- Curse you, Mark!

- Leaving the remaining 5% reserved for watching and waiting for cheaters to strike.

- Haven't lost yet.

Let's go. - And we didn't have to wait long.

- Thirty four, red.

- Oh good, I'm on red.

That's awesome.

- Because at the roulette table, Kevin Coda somehow hadn't lost a single game.

- Too good.

I'm too good.

- Which is strange, because in roulette you basically place your money on either a red or black space, and if the ball lands on your color, you double your money, but if it doesn't, you lose it all, meaning on average, you should be losing about half the time.

- Looks very suspicious.

- I've got an idea.

- I decided to take a closer look by using a stylish pair of sunglasses that also doubled as a covert spy tool through mirrored lenses that would let me face away from the table while still getting a perfect view of the gameplay, allowing me to play detective while looking totally natural to a nearby layperson.

Totally natural.

- I'm gonna do red.

Oh yeah. - Alright, no more bets, folks, no more bets.

Here we go.

Black. - Oh, I'm on black.

- Um, excuse me.

- Oh, hello.

- I happened to notice something at this table with my reverse seeing glasses.

So, you mind if I look at your chips?

- Yeah, you can take a gander.

- You... filthy...

genius... Cheat!

This thing drives itself?

- It drives itself.

- Let me see.

That's incredible!

- Roulette's a fifty-fifty game, but if you have a robotic poker chip, it lands on the correct color every time.

Show me red.

Or black. Just keep racking them in, one at a time.

- Now, the truly ingenious part of Kevin's hollowed-out poker chip robot wasn't the inset coin cell-powered custom printed circuit board, or that it receives its command from what's essentially a garage door remote.

It's the fact that the tiny motors he used came out of your phone because he removed the offset weight from the silent call vibration motor and replaced it with the wheel.

If you repeat that three more times, you can drive anywhere you want, and roulette becomes a solved game.

- Good luck catching this.

- I love it and it's now mine.

With the remote.

Are these all your chips?

- These are mine. Yeah, I was raking them in till you caught me.

- You're gonna keep those and I'm gonna keep this.

We got a cheater!

We got a cheater.

- But I may have taken a victory lap too soon because while catching Kevin Coda, I completely missed a different sneaky cheater at the blackjack table.

- I'm Tom. My cheat is a camera up the sleeve when he presents the deck for me to cut.

My friend's gonna be on a laptop indexing the entire deck for me.

I'm guaranteed to win every single time.

- And I should have thought of this, because famously in 2011, a high-tech cheating ring won millions using this exact device in Las Vegas, and because one person would scan while a second person would analyze the data and a third would place the correct bets, they got away scot-free.

And since I completely missed Tom's cheat, - Now, mind if I cut the deck real quick? You know, for some good luck.

- He was free to rack up his ill-gotten chips.

- What's up?

- I was gonna have to pick up the pace because tonight we were the house.

- Some of you look very suspicious.

- And like every other casino in the world, the house always wins.

100

And by the way, they don't just barely win.

101

The casino industry around the world rakes in $1 billion every single day, and worse yet, 90% of that billion comes from 10% of the population, which repeated studies show are all the people that have clinical gambling addictions.

102

So, the entire industry is predatory and statistically speaking, spending enough time in a casino will make you a guaranteed loser.

103

And this is why casinos spend so much money on gambling surveillance systems, because if anyone is consistently winning their money, the only possible explanation is they're cheating.

104

And when you see just how clever some of these cheats are, it's real hard not to root for the underdog.

105

For example, one team managed to disguise an infrared ink pen inside a fake thumb that they then used to secretly mark all the best cards, then by using special infrared contact lenses, the marking became obvious only to them, or another group built a remote control roulette ball with an internal electromagnet that would slam the ball down as soon as it passed over the correct color.

106

Or even a very simple custom-built card reading device disguised as a phone that can read these tiny random dots along the edge of each card, which might seem impossible, but in reality, this is exactly how every single barcode scanner works.

107

By the way, that barcode crunch was brought to you by a giant version of my brand new toy...

108

the Crunchinator!

109

Which is essentially your very own at-home hydraulic press where you can multiply your strength by thirty and crunch whatever you want, now conveniently found at a store near you.

110

So, I clearly had my work cut out for me tonight, but I wasn't alone because I had my highly trusted pit boss.

111

- Alright Bob, what are we seeing?

112

- Uh, so far it looks like everyone's having fun, winning money, and- - Bob, no. Like cheaters, you're looking for cheaters.

113

- That's right, I'll start that now.

114

Sorry, I just... I'm sorry, yes.

115

- You're the pit boss, that's like your literal one job, Bob.

116

- But whatever these cheaters were hiding, they hid it well.

117

- Six please.

118

11 on 6. What happens if I win?

119

- And I ended up keeping a watchful eye over some pretty mundane table conversations.

120

- Yeah - So, I do stuff for film and TV and then my channel is showing like behind the scenes how I do it, puppeteering and on set, stuff like that.

121

- I've been taking baking classes.

122

I'm getting very into decorating.

123

- We met before at Vid Summit once because I was with uh...

124

- So, to help with my boredom, I decided to randomly hone in on Davis, a creator who didn't usually sport Tom Cruise aviators.

125

- Well means you have a bad hand.

126

- Hey Davis, - Yes sir.

127

- I really like your glasses. They're cool.

128

- Thank you very much.

129

- Do you always wear them?

130

- I'm a theater kid, so it's all right here.

131

The eyes are the window to the soul.

132

- Can I try?

133

- Yeah, absolutely, if you... Are you... You know.

134

- How do the cards look?

135

- I'm not a betting man, but my guess is this is a king.

136

And I bet this is an ace.

137

- An ace of what?

138

- Spades, a jack, and a six or a nine.

139

Because you can see what the cards are using these glasses somehow.

140

- I'm Davis and I have these special glasses that allow me to see the back of everyone's cards and know what their actual values are.

141

- And that's because Davis found a way to write the value of the card with a very light green ink on the back of our otherwise fully red playing cards.

142

So if you view them through these red tinted glasses, the green writing jumps out because it's on the exact opposite side of the color wheel and absorbs almost all red wavelengths.

143

So in order to use his smart cards, he arrived early at the event and bribed a dealer to swap them for our standard playing cards.

144

But despite all this cheating...

145

- How have you been losing so much when you have a cheat?

146

- You literally know every card and this is all you have?

147

- I'm really bad at poker.

148

- Well, these are mine now.

149

Put them in.

150

The house always wins.

151

- The house always wins.

152

- But with two cheaters down, I was feeling good, but unfortunately my newfound confidence made me miss the flagrant rule violation passing right under my nose, fourteen inches under my nose to be exact.

153

- Oh hey man, it's me, Mark Rober.

154

Do you know that if you put this into the body of a cat, it would die?

155

And the science behind that might surprise you.

156

Catch you later.

157

It's me, Mark Rober.

158

Look at my abs.

159

- And if you're wondering how this happened, given our Michael Reeves AI Face Detection Defense System, - You know, if you hit a kid with a Chevrolet Silverado...

160

- I can assure you it was working flawlessly, because earlier that night when Michael tried to sneak in as a waiter, - Hey man, can I get you anything to drink or...

161

- It successfully flagged him and Bam called it in.

162

- He's got such juicy pecs, bro.

163

I just want to get his abs!

164

- And it did the same thing when he tried to come in as a backup pit boss.

165

- Grab some hors d'oeuvres.

166

I'll swing on you.

167

- He's slippery!

168

- But this time it seemed Bam had missed the warning because she'd been busy.

169

- Would you like a dessert?

170

- Yes, please.

171

- Trying out the dessert cart. But in fairness, - Have you had the angel food cake yet?

172

It's really good.

173

- the dessert cart treats were really delicious and a magnet for juicy gossip.

174

- Figuring out where I should lose my money next.

175

- OK. - No, something was going on there or he got really lucky.

176

- Apparently Nate Scoville was having a lot of luck.

177

- 50 on seven.

178

- With the number seven.

179

- He's like, I don't even know what I'm doing.

180

- So I decided to take a closer look and see for myself.

181

- Seven. Hey Mark.

182

- Now my presence didn't seem to faze him.

183

That is until he rolled...

184

another seven.

185

- Wait, what did you just get?

186

- Wait, OK, wait a minute.

187

- Let me see those dice.

188

Are these potentially loaded?

189

- That looks pretty bad.

190

- Oh no. - Look at these dice.

191

Four, five, six on one side. Four, five, six on the other.

192

One, two, three. One, two, three.

193

How does that help you?

194

- I'm Nate Scoville and I made dice that are more likely to roll sevens.

195

- Basically, Nate spent a week meticulously crafting these fake dice, because in craps, getting a seven on your first roll instantly doubles your money, and with these rigged dice, he's more than doubled his chances of getting a seven, because the lowest possible total you can get is a five combining a one and a four and the highest possible total you can roll is a nine, combining a six and a three.

196

So all your possible dice rolls are between a five and a nine, with seven being the most likely.

197

- You dirty scoundrel!

198

Man, how much money have you won?

199

Where's all your chips?

200

- But even if you double your chances, it's still a game of chance, and sometimes you just get unlucky.

201

- Five! Mark it. Eight! Nine! Eight! Eight! Five! Five! Eight!

202

- Wait, that's it?

203

Actually, here, you can have them back.

204

Just keep them, just keep them.

205

- That did not feel great.

206

- Five hundred on seven.

207

- With another one on the board, I apparently had to remind everyone just exactly who they were messing with.

208

- It's me, Mark Rober.

209

Look at my awesome abs.

210

It's me, Mark.

211

- Hey! - Hey, welcome to the event, bud.

212

Now, let me tell you what's going on.

213

- Security, this is Michael Reeves.

214

- I don't know who that is.

215

Can you guys get him out of here?

216

- Ask a question only Mark Rober would know.

217

- How far away is Mars?

218

- Oh, easy.

219

How far? - A couple.

220

- 140,267,924 miles.

221

- That's not fair.

222

He's Mars Rover.

223

- Get him out of here.

224

Get him out of here.

225

- It was gonna take a lot more than a Temu muscle suit and nine-inch lifts to sneak past our security.

226

- I'll get in there someday, Mark.

227

I'll get in there someday.

228

- I was losing control of the night and the harder I tried, - Let me see those glasses.

229

- The more I came up empty-handed.

230

- Actually, these kind of help.

231

- And just when I thought things couldn't get any worse, - Excuse me, could I have your attention, please?

232

- Becky Stern made an announcement that changed everything.

233

- I would love to raise a toast tonight.

234

May you always know when to hold them, know when to fold them.

235

May your bluffs be believable and your cheating go undetected.

236

And finally, I saved the best for last.

237

Mark Rober is going to buy every single person in this room a new Rivian.

238

You get a Rivian.

239

- Oh, that is not true.

240

- And you get a Rivian.

241

- Oh god! I need a new car so bad!

242

- Not true! That's not true.

243

Oh God. - I'm fine, thanks for the Rivian, Mark.

244

- Mark! Mark! Mark! Mark!

245

- No, not Mark, not Mark, that's not true.

246

- And while it might have looked like Becky's speech was just an excuse to get herself a Rivian, the truth was far more sinister because earlier that night I had caught her, - Wait.

247

- spewing cards.

248

- What was that?

249

Let me see the back of those cards.

250

I've seen those.

251

Aha! In fact, all night I'd been finding cards littering the floor.

252

What are all these cards doing here?

253

- I don't know.

254

- I'm collecting these.

255

And it turns out it was Becky all along.

256

What is this?

257

- This is my card launcher.

258

- Becky had hacked an Uno Attack dispenser into a remote-controlled fifty two-card pickup, but she wasn't using it to cheat.

259

- I'm not actually playing, I'm just watching.

260

- Why would you have a card launcher?

261

- To distract people.

262

I'm Becky, I'm the distraction broker.

263

I have these business cards and they have our menu of distractions, my card launcher for 250 chips, a remote controlled rat for 150.

264

- The one I'm the most curious about on here is passing gas.

265

- I have a device.

266

- You have a farting device?

267

- And that's my strategy because I really can't get caught.

268

- So, I can't take your device because you're not actually cheating with it.

269

Other cheaters are just paying you to make distractions.

270

- Right. It's all because I can't keep a poker face and I'm like, how do I be successful in this environment?

271

My best chance is to sell the distractions rather than trying to win the chips myself.

272

- That's a dirty loophole, and you know it, but my hands are tied.

273

Bad luck. - Something told me all that glass was part of a distraction.

274

That's something being Kevin.

275

- I think all that glass was a distraction.

276

- It was, she's a distraction broker.

277

- I know, Mark. She's trying to do something.

278

I don't know what her plan is.

279

- Somebody did something while that happened!

280

- I'm holding onto my chips.

281

- I'm just helping.

282

- Bam and I rushed upstairs to try and figure out who would use Becky to gain an edge, but there were no weird contraptions or unusual gameplay at any of the tables, and it seemed like the culprit might just get away.

283

But then Bob finally decided to do his job and uncovered some sketchy business.

284

- Uh, they're over at that table right there.

285

- The one in the bright orange suit?

286

- Yeah, yeah, there's no way they can make that much money in the time that they played.

287

- He's got a lot of money.

288

- And while having a lot of chips doesn't make you a cheater, randomly pulling them from your pocket doesn't help your case.

289

- Wait. Turn off the lights.

290

- This was a cheat I'd actually anticipated, because making counterfeit poker chips is one of the oldest tricks in the book, and it's why the actual design of casino chips is a tightly guarded secret.

291

A single ceramic poker chip is loaded with RFID tags, UV markings, microtext, and holograms, and my chips had a little secret of their own.

292

- You'll notice all of the official CrunchLabs chips have a UV reflecting star on them, and yet these chips don't have such a star.

293

Lights on. Give me everything you've got.

294

Let me see all these.

295

A million dollar chip.

296

Dirty. - That was good.

297

That was good.

298

Alright, now you gotta get out of here.

299

- We were getting close to giving away the money, but the way this night had been going, I was terrified of the final stretch.

300

- Uh, OK, we're coming up on the last hand here.

301

- And as expected, the distractions started coming in strong.

302

My tightly-controlled casino was starting to become a madhouse.

303

- We can't have that.

304

Who's doing that?

305

Who's in charge of that?

306

- And we knew there were more cheaters still on the floor.

307

Even guests were starting to tip me off.

308

- Mark, I found a cheater.

309

- But when I confronted them, - Are you punishing luck? In a casino?

310

Did I lose?

311

- Yeah, yeah, yeah, for sure, for sure.

312

- they wasted so much of my time playing dumb.

313

- Allen. - I don't know what happened.

314

I just kept going all in and it kept working.

315

- That I missed the other cheats right behind my back, like Christina Ernst, who had a garter belt that helped her count cards.

316

- My name is Christina.

317

I'm the creator behind She Builds Robots and I want to sit back, relax, and enjoy the party.

318

So, I programmed this garter to do card counting for me.

319

I'll be manually inputting the cards that I have and then we'll get a little visual LED feedback of what my next move should be.

320

- Eleven and a double.

321

Thank you very much.

322

- I did not get caught.

323

- I missed Rox, who had the ridiculous hack of just bringing in only twos for some reason.

324

- My hack was the simplest of all, sleight of hand.

325

- You have to keep your cards above the table, sir.

326

- Somebody else on my table drew two of the same card.

327

- Pit boss!

328

- They called the pit boss, but after fifteen minutes of trying to figure it out, they still didn't catch me.

329

- But I really wanted to catch one more cheater before time ran out, so I honed in on one table and one person that seemed to be luckier than statistics would allow.

330

- Take your winnings.

331

Thank you. - Rolled nine twice in a row.

332

- I did. - Can I see the dice?

333

They look a little suspect.

334

- And that's because I was almost certainly holding a pair of loaded dice.

335

Now, when the dice are loaded, it simply means the center of mass is shifted away from the number you want to land face up, because the lower center of mass, just like a Weeble Wobble, that side always lands on the bottom.

336

And I remember reading once, this is done by hollowing out the part of the die under the desired number, but that lower density means they'll float like an ice cube.

337

- Hold on a second, can I see your drink?

338

Thank you. Wait.

339

- Now, they're just wet.

340

- They were supposed to float.

341

- Thank you.

342

- Hack nine.

343

- Nine! I still get money.

344

- There's something fishy here.

345

- But after having Bam check the footage, it turns out Dora was winning with different numbers throughout the night.

346

- Ten! Oh, a twelve!

347

- I got a four.

348

Six. - Yes!

349

- Completely ruling out my weighted dice theory as I left to announce...

350

- Everyone has to turn in their chips now.

351

- It was time to count the chips to see who our top three earners were, and out of those three, which one would be earning the $10,000 for the charity of their choice.

352

- OK, the results are in.

353

The three top chip winners, Dora.

354

OK, so Dora, were you cheating?

355

- Wait, wait, shake my hand.

356

Was I cheating?

357

- Whoa, that's a hot handshake.

358

What was that about?

359

I knew it was something with the dice.

360

- Because these weren't just loaded dice, they were heat-activated loaded dice.

361

Basically, the core of the dice is filled with wax, which when solidified holds heavy steel ball bearings in place, so when she held the dice in her hands, the 10 watt silicone heating pad she concealed in her fancy gloves would melt the wax, allowing the steel ball to sink to a new position opposite the desired number she wanted to roll, meaning they were passively reprogrammable to land on whatever face she wanted, which is why it was impossible for us to detect a pattern.

362

- Holy crap, that's genius.

363

OK, well done, well done.

364

- And our next winner...

365

- Daniel, get up here.

366

OK, Daniel, were you cheating?

367

- No. - OK, were you cheating?

368

- Yeah. - And what was your trick?

369

- Fabricating chips.

370

In the bathroom.

371

- So even though I'd taken away all the chips Daniel had on him, every time he went to the bathroom, he was just making more.

372

- Mark just sent over the invite for his casino night.

373

And if we look at the corner, we can see what the chips look like. So, if I can order all the supplies I need to make them...

374

This is the Semi-Convincing Asset Manufacturing case. Inside, I have everything I need to create a fake poker chip in the bathroom.

375

- Genius. Alright, and the last one, Allen Pan.

376

Allen, did you cheat?

377

- No. - No, but like really?

378

- Really. - Really?

379

- This is actually bizarre.

380

I don't know why I'm here.

381

- And yeah, this was true too.

382

- How does this work?

383

I have two of these.

384

What is that?

385

- Allen had just got dumb lucky.

386

- Oh, he's got two pair!

387

Allen, what?

388

- I have so many chips now.

389

I have a ten and a nine.

390

What does that mean?

391

- That's good!

392

- This is so many.

393

I love poker.

394

I actually don't know what's happening.

395

- OK, well, let's all hope Allen doesn't win.

396

Bob. And the minute it was time to reward the top hacker of the night...

397

The first ever CrunchLabs Cheat the Casino Games winner is...

398

Dora! Was the minute everything changed.

399

Wait a second, it's cake!

400

Who stole the money?

401

Did anyone see anything at any moment?

402

Science Bob, get everyone out of here.

403

Security, search them as they leave, make sure they don't leave the premises.

404

We're going to figure this out.

405

Everyone, clear out.

406

- Everybody, out. We'll figure this out.

407

- Sorry, I haven't eaten all night.

408

It's actually really good.

409

- As the horrors of what had transpired here really dawned on me, - It's cake!

410

- I vowed I wouldn't let whoever stole this money for charity get away with it, and what we would discover would shake the very foundations of science YouTube forever.

411

- It's cake.

412

- And the first clue was obvious.

413

- The cake, right?

414

The cake money.

415

How did it get swapped out?

416

- The thief was obviously a baker.

417

- Does this lift?

418

- Oh, wait.

419

- Is there a trap door?

420

- I was trying to pick up the cake, but there's actually just like a trap door here.

421

- And when there's a trap door, - Let's take this off.

422

- the obvious question is...

423

- Where does it go?

424

Yeah, the whole thing just moves.

425

- Oh, wait, wait, wait, right there.

426

- There's a conveyor belt?

427

- The money fell down and it took it somewhere.

428

- A hidden conveyor belt meant that we were probably at the start of a very long search for the...

429

- Hey, the money!

430

We've got it.

431

- Oh, so it's not gone.

432

- That's it.

433

- It's cake again!

434

- This person is trolling with us.

435

- And if our thief was in fact a troll, it narrowed the suspect list down to about one person.

436

- Did Michael Reeves do this?

437

He has a motivation.

438

- I will say suspect number one.

439

- So, from here it had to have gone somewhere.

440

- We need to watch the security footage.

441

- That's a great idea.

442

- We need to see someone being suspicious around this area.

443

- We had cameras recording every single thing that happened that night, and this is how we would figure out who swapped the money with this delicious...

444

- You're eating a lot of cake, Mark.

445

Is it really good?

446

- It is kind of good.

447

- I told you.

448

- It was time to get to work before I ate the rest of the evidence.

449

But before we do that...

450

- Alright, if you wanna try and figure out who stole the money, everything you need to solve the mystery you've already seen in this video.

451

So this is your last chance to go back and Scooby Doo it yourself.

452

Otherwise, here's how we did it.

453

Dang it. We can take a look at the stage.

454

- Thankfully, the money was under constant surveillance, which begged the question, how in the world did someone switch the money with cake without immediately getting noticed?

455

- I mean, at this point, is it cake or is it money?

456

Can we go back in time?

457

- Oh, OK, OK.

458

- So back in time we went.

459

- I mean, so far it seems fine.

460

- And... - Oh! There it was, right there!

461

It flipped.

462

It just flipped.

463

- Everyone's looking in that direction, that must be it.

464

- May your hands be full, your bluffs be believable, and your cheating go undetected.

465

- Oh, you know what this is... This moment.

466

- I saved the best for last.

467

- Oh, Becky!

468

- Mark Rober's gonna buy every single person in this room a new Rivian.

469

- Oh, that is not true.

470

Oh look, that's me saying no one gets a Rivian.

471

- People are chanting.

472

- Becky dropped all the cups.

473

- There! There's the flip!

474

- Yeah, that was part of her distraction.

475

- Whoa, wait.

476

That was such an act.

477

Oh my God. - That was it!

478

- I mean, who else did she talk to?

479

- Ooh, that's a good idea.

480

- So we reconfigured our security system algorithm to focus on Becky instead of Michael.

481

- Clearly she talked to a lot of people throughout the night.

482

- Which meant we were able to filter down the last interaction she had right before the toast.

483

- OK, wait, here she goes, here she goes.

484

- And it led to a very unlikely suspect.

485

- I see her talking to...

486

- Yeah, yeah, to Bob.

487

- What?! - Your right hand man.

488

- No. - But as much as I didn't want to believe it...

489

- Yeah, they just passed each other and his hands are behind his back.

490

No one walks around like that who's an honest person.

491

- Bob would not do this.

492

- The footage was undeniable.

493

- He's got the money.

494

Wait! Wait! How did nobody see him literally walk out with the bag of money?!

495

- No one would stop the pit boss.

496

- Yes, I think that's it, right?

497

- And led to the only rational conclusion.

498

- Do we have him leaving?

499

Do we have him?

500

- He walked out.

501

- Oh, wait!

502

- Where did he go?

503

- That's his desk.

504

- He goes to his desk.

505

He puts it on his chair.

506

I mean, that means it's just literally back over there, right?

507

- It's like...

508

- Let's go get Bob.

509

- And just as we were about to close the case, - Mark.

510

- Dora made an interesting observation.

511

- What's up?

512

- Look at this.

513

- Thank you everyone for coming back in.

514

First of all, I wanna sincerely apologize and the good news is we know who stole the money.

515

And we know where the money is.

516

And they're in this room.

517

So, to figure this out, the first thing we did was we checked the pedestal.

518

It's a false bottom.

519

So, it's rotating on a hinge that's attached to a brushless motor that turns exactly 180 degrees, and then it flipped up the fake cake.

520

The real money dropped down the pedestal onto this conveyor belt under here that's running to the edge of the stage.

521

We checked the footage to see when it happened.

522

It happened exactly when Becky was making a toast, unlawfully telling everyone I was giving them a Rivian in this room, as a distraction.

523

So the question was, who was the last person to talk to Becky and exchange money?

524

And it was the same person who touched the money last.

525

None other than Science Bob Pflugfelder.

526

- OK, whoa, whoa, whoa.

527

No, it was not me.

528

I have no money.

529

I wouldn't do that.

530

- Science Bob, we saw you take a black duffel bag, high five the security, and put it at your desk.

531

- OK. - And we have the duffel bag right here.

532

- No, no, no, no, no, no, no, no, Mark.

533

Hey, hey, hey, hey!

534

All I'm asking is please don't open the bag.

535

- Interesting.

536

- Now given all that, Bob, you would have a lot of explaining to do if we opened this bag and found $10,000 but we're not going to find $10,000 are we, Bob?

537

- No, you're not.

538

- Let's open the bag.

539

- Do not open the bag.

540

- Open the bag.

541

- Right here, Bam, on the stage.

542

Bob, no. The earth is flat?

543

Bob, you do have some explaining to do.

544

A mouse pad, for God's sakes?

545

- It was free at the meeting.

546

Come on. - It's flat, bro?

547

- Bob, are you flat Earth-curious?

548

- They have some compelling points.

549

- I wish you had stolen the money instead.

550

- All of this looks incredibly suspicious, but it didn't actually prove he stole the money.

551

And this is when Dora made a very interesting observation that blew the case wide open.

552

Because what we saw...

553

- While no one person spent a significant amount of time at the front of the stage where the money was hidden, a certain dessert cart did for 5 minutes, after which it made its way around the room for 15 minutes.

554

Eventually ending up behind the snack bar, but when we checked it, we found nothing.

555

But thanks to the Michael Reeves AI Face Detection Prevention System, we could tweak the algorithm to find the one person who wasn't in the room precisely for the same amount of time the cart was making its final round.

556

- It came back with one name, someone that no one suspected.

557

The person wearing the same obnoxiously bright shoes that we actually saw poking out from the dessert cart.

558

The person who came yesterday to verify this money was real, YouTube's formerly most trusted science teacher, Hank Bartholomew Green.

559

- Not you, Hank.

560

- It's very impressive, Mark.

561

Look, I ran the numbers, the number of engineers in here, there was no chance I was gonna win.

562

I needed some guarantees.

563

- I trusted you, Hank.

564

- That was your first mistake.

565

You let me count the money, got to inspect it, and I get to install my little device.

566

- You needed everyone to look away.

567

- So I bought myself a distraction.

568

- I'm offering some services tonight.

569

- Yes, I've heard.

570

- I was wondering if you might be interested.

571

- I am very appreciative of your offer.

572

I would like you to give a toast.

573

- And you swap the money for cake.

574

- Yeah, turns out it's easier to counterfeit cash when it's baked.

575

- Of course, you've been taking baking lessons.

576

- I've been taking baking classes.

577

- Baking classes, is that like an online thing?

578

How do you do it?

579

- No, I go to a place.

580

I like to be prepared, Mark.

581

- And when everyone was watching Becky...

582

- I slipped into the cart.

583

I took the cash.

584

And my friend, it is long gone.

585

- Hank. You're bluffing.

586

You had enough time to take the money off the stage, that's true, but you didn't have enough time to remove the money from CrunchLabs, did you, Hank?

587

- Mark, you're never going to find it.

588

- You're right, we never would have found it.

589

If it wasn't for one tiny clue, when we traced the cart around, we noticed that it made one convenient stop during the blackout.

590

And that's where you made the mistake.

591

- We need to watch the security footage.

592

- And unfortunately for you, it was cream cheese vanilla.

593

My favorite flavor.

594

And we noticed when the light turned back on, this vase was carelessly turned ninety degrees, which means this would be the final resting place of the money, and your plan was to come back later, once everyone had left to retrieve it.

595

So Dora, please come collect your winnings as I dramatically break the vase with this conveniently placed hammer.

596

What? Are you serious?

597

It's cake again!

598

Give me this.

599

- You'll never catch the elusive Hank Green.

600

- Security, get him!

601

- Get him! - We got him!

602

Give it up for CrunchLabs security.

603

Thank you, you legend.

604

What the- Michael Reeves!

605

- Mars Rover!

606

- Real security!

607

- Mars Rover.

608

- Get him out of here!

609

Thank you, everyone!

610

Dora, enjoy your earnings.

611

- So once again, the house always wins and cheaters never prosper.

612

Unless you're really good at it.

613

- I thought this was real money.

614

I took a picture with it.

615

- These... are all the genius engineering builds I confiscated at the party.

616

They all have one thing in common, this wasn't their first attempt.

617

- What? - Because the number one mistake people make when trying to build something is expecting their first version to be their last.

618

But all great engineers not only build things again and again.

619

But they redesign them again and again.

620

Failing, learning and refining again and again.

621

Which is why for the past three years, every single Creative Kit, Build Box, and Hack Pack was designed on OnShape because just like millions of professional engineers around the world, that's the program our amazing toy engineers insist on using.

622

Because OnShape runs entirely in the cloud powered by AWS, meaning you can design through your browser from virtually any computer, but also because you can collaborate simultaneously on the exact same part.

623

And if you ever get stuck, OnShape even has built-in AI tools to help you out.

624

Making that redesign and building process a whole lot faster.

625

So the next time that awesome CrunchLabs box shows up on your front porch, just remember that the toy inside wasn't version one.

626

Thanks to the power of On Shape, it was at least version 30.

627

So don't worry about getting it perfect and start with your version one on the exact same software we use here at CrunchLabs.

628

And while businesses get it free for the first six months, it's completely free for students and teachers forever.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
