and stole my backpack.

実は中にキラキラ爆弾と オナラスプレーが

But what they'll soon find out

特製リュックだ

is that thanks to some high-tech glitter

誰か漏らした？

and fart spray delivery mechanisms,

また車上荒らしだ

that's no ordinary backpack.

でも この窓…

- [Thief] Ain't nobody (beep) back here, right?

実は防弾ガラス

- And this guy's also trying to break into my car,

笑えるね

but what he doesn't realize

サンフランシスコで毎年 ２万台に被害が

is those are bulletproof windows 'cause that's just funny.

黒幕がいるのか

(beep)

組織犯罪か個人の犯行か？

Every year, 20,000 cars are broken into

盗品の行き先も謎だ

in the city of San Francisco,

キラキラ爆弾で

but who's behind all these break-ins?

電話詐欺会社を 閉鎖させた時みたいに

Like, is it organized crime, or gangs,

ベテラン記者と組んだ

or just random individuals?

８か月でおとりの車が 25回 襲われたから

And then what happens to all the stuff that they steal?

犯行映像が撮れたし 防ぐ方法も見つかるかも

Well, just like when we used the power of glitter

キラキラ爆弾は今回が最後だ

to infiltrate and shut down

本当にね

those terrible scam call centers in India,

オナラスプレーへの いいリアクションも撮れた

I'm happy to report that having teamed up

安全だけど強烈だ

with a veteran investigative reporter,

Ｍ･カルキン並みの反応を期待して

and gotten our bay car broken into 25 separate occasions

発明のきっかけは

over the past eight months,

５年前に来た置き配泥棒だ

we now have a much clearer picture of what's going on,

エンジニアの技術と 映画のアイデアを融合させて

and even some thoughts on how to stop it.

キラキラ爆弾は進化してきた

And as this video is the conclusive finale

回転 スプレー 点滅 粘着 パンチ 飛行

to the whole glitter bomb series, this time for reals,

インドの電話詐欺会社に送り込み

I'm so happy to report that we finally got

業務停止にしたことも

some really good reactions to that perfectly harmless,

去年で最後じゃなかったかって？

yet wretchedly abhorrent fart spray,

その予定だった

including one that's not too far off

でも今年 車上荒らしに遭って

from Macaulay Caulkin's here.

爆弾をやめるって考えを 改めることに

(Macaulay coughs)

窓がない

Now, if you haven't seen any

ひどいぞ サンフランシスコ

of my other glitter bomb videos,

去年もおとりの荷物で実験したけど

the 15 second recap is that five years ago,

犯罪の裏を暴くような 映像は撮れなかった

these two took a package from my porch,

だからもう一度だけ 爆弾を設計することに

which inspired me to combine my engineering skills

車上荒らし向けの特別仕様だ

with my Christmas time affinity for Kevin McCallister.

キラキラは遠心力じゃなく

- Yes.

6.2メガパスカルの 圧縮ガスでまく

- And that not only led to different versions

自転車ボンベをパイプにつなぎ

of glitter bomb bait packages that would spin,

高速モーターで操作

spray, flash, stick, punch, or fly,

これを２つ重ねたら

but it eventually led us over to India

中に生分解性のキラキラと

where we ended up infiltrating, then shutting down

オナラスプレーを詰める

five of those terrible scam call centers.

モーターでボンベが作動し 中身をまく仕組みだ

But Mark, you object, you said last year

中心の特製回路で動きを制御

was the final glitter bomb,

会話もできるようにした

and that was true until earlier this year.

クラクションもつけて

I had the unfortunate realization

特製のリュックに全てを入れる

that glitter and fart spray

噴射口はここだ

hadn't solved all forms of crime worldwide

今まで同様 側面のスマホで 撮影できる

when my own car was broken into.

ＧＰＳ追跡や カウントダウンも可能だ

I'm missing a window.

盗まれた荷物の行き先は不明

Not cool, San Francisco.

回収できないかも

Not cool.

Ｔモバイルに頼んで

That also made me realize

映像はクラウド上に アップされるようにした

our 11th hour cobbled together car package last year

通信速度は検証済みだ

never got enough footage to uncover

最後に回路のカバーと

who was actually behind all the San Francisco car break-ins.

噴射口を隠す ストッパーを取り付けた

So 10 months ago, for one final time,

目くらましに

we completely redesigned the glitter bomb

服と壊れたパソコンを入れて完了

from the ground up.

スーツケース版も作ったから

Only this time, it would be custom built just for cars.

ウワサが広まっても大丈夫

For starters, instead of using centrifugal force

車内の８台のカメラを 大容量電源につないだ

to fire the glitter, this year we'd be using

リュックも電源につなぐ

900 PSI of compressed gas

１本はモーターやスマホの充電用だ

because if you take a CO2 bike tire inflator

もう１本は安全ピン

and attach a pipe to the outlet,

抜けたら装置が起動する仕組みだ

then connect the high torque servo motor

おとりの車も準備した 窓はポリカーボネート製

to the opening valve, and then repeat that configuration

防弾ガラスの素材だ

and stack them on top of each other,

トランクに装置がある

well then when you load those pipes

衝撃を感知すると

with copious amounts of biodegradable glitter and fart spray

タンクのガスが出て ピストンを動かし

and then trigger the servo motors,

犯人を驚かす

that highly compressed CO2 is gonna very quickly

最後にパソコンのファンを外し

push out anything in the pipe that gets in its way.

バッテリーで充電する ＧＰＳ装置をセットした

At the core, we still have a custom printed circuit board

データを消されても追跡できる

that will make all the decisions for the device,

パソコンは爆弾なしで リュックに入れ 盗ませる

in addition to talking to us

ＡＢＣ７のベテラン記者 ダン･ノイズに協力してもらい

via a two-way cellular connection.

パソコンの行方を追跡しよう

Then we slap on a car horn for good measure,

数か月かけて装置は完成 現場に送り出したら待つだけ…

and place that whole compact form factor

さほど待たなかった

into the base of a custom sewn backpack

でも作品を割られる前に

with external access to the outlet nozzles.

自分のを割ろうかな

Like in years past, we'll still capture footage

３　２　１…

using a pair of phones that get tucked into the sides,

うまいよ

with the added benefit of serving as the backpack GPS

僕が長年動画を作ってきたのは

and the speakers for the countdown time.

エンジニアの考え方を伝えるため

And once these backpacks are stolen,

どういう意味か？

they'll of course be on the move all over the place,

頼むよ

and since there's no guarantee we're gonna get 'em back,

おっと

for the third year in a row,

どう？

we turn to my friends at T-Mobile

触媒の量を変える

to make sure no matter what,

いいね

we get the footage from the cloud

失敗も大事だ　学びがある

given the complete coverage

それが分かれば サッカーやピアノも

and crazy speeds of their network

できるまで挑戦できるようになる

that I've actually gone out and benchmarked myself before.

違う解決策を思いつくかも

Finally, we lock up the bottom compartment

エンジニアの考え方で 見方も変わり

to prevent tampering,

楽しむ方法が見えてくる

then use a rubber stopper glue to a patch

だからこのビルドボックスを作った

to plug and conceal the outlets.

毎月おもちゃが届くよ

Then as a decoy to divert suspicion,

ありがとう

we got some clothes and a bunch

楽しんで

of old non-functional laptops to place in each bag.

また来月

We also created a second version

僕と一緒に作ったら 仕組みも学べる

with a suitcase form factor and identical guts

遊びながら脳を鍛えて

in case word got out about the backpacks.

世界を理解したいなら…

Then the car itself has eight hidden dash cams,

クランチラボ･ドットコムから

all powered by a 2,000 watt hour

申し込んで

camping battery in the trunk

成功だ

that also plugs into the backpack with two barrel jacks.

最初に気づいた

One to keep the entire device

僕らは黒幕を暴こうと必死だが

and both phones at 100% charge until stolen,

犯人も必死で正体を隠してる

and the other to serves sort of as a digital trip wire

でもこっちには エミー賞受賞の記者がいる

so the backpack knows exactly when it was stolen

やがて犯人の車がカメラに映った

to initiate the stolen bag protocol.

ダンなら持ち主を特定できるが

We also served up two more surprises this year

ナンバーが外されてた

by first creating a bait car

３度目でチャンスが

with impossible to break polycarbonate windows,

ナンバーがついてた

which is the same stuff bulletproof glass is made of.

ところが調べたら驚きの結果に

That car also has the added benefit

持ち主は サンフランシスコの大学教授で

of a microphone in the trunk

チャータースクールの理事だった

for detecting when someone's trying to break the window,

ダンが住所を調べ 自宅を訪ねてみると

which will of course release the air in this tank,

とてもいい人だった

triggering this pneumatic piston

数週間前にナンバーを 盗まれたそうだ

with a special surprise on the end.

ダンが調べた結果 分かったことがある

And as a final idea, we took an actual gaming laptop,

犯人が狙うナンバーは…

removed the extra fan, and in its place,

ジョージアだ

added a GPS tracker that would continuously stay charged

バレにくい 自分のと似た車の物だった

by using the laptop battery.

犯人は僕らの捜査の手を逃れたけど

That way we'd always know where it was,

キラキラ爆弾からは逃れられる？

even if they wiped the hard drive.

ネタバレ！

The thought here was to put that laptop in a backpack

無理だ

to actually get stolen with no glitter involved,

何だ？

and then with the help of Dan Noyes,

爆弾とかじゃないよな？

who spent 30 years as the chief investigative journalist

追跡装置か？

for the San Francisco ABC7 news team,

何だよ

we could trace the laptop's footsteps

追跡装置だ

to try and get some answers.

これが装置？

So after a couple of months

早く捨てろ

of designing, testing, and building,

ああ

we put them out in a few different cars, and we waited,

早くしろ

and we didn't have to wait long.

捨てた

But before I subject you

４　３　２…

to gratuitous amounts of broken glass,

こいつは後部座席を剥がし

I'm gonna start off with a little broken glass of my own.

電源を盗もうとしてる

Three, two, one.

トランクの中の荷物も 危険ってことだ

(glass shatters)

15　14　13…

Nice shot, Eloise.

犯人はリュックを取ったが…

I'm Mark Rober, and for over a decade,

パソコンを捨てた

I've been making YouTube videos to showcase what it means

４　３　２…

to think like an engineer.

次はいい反応が撮れたよ

But what exactly does that mean?

泥棒って盗みは簡単にやるのに

You ready?

責任は負わないみたいだ

(liquid explodes)

今回は映像をそのまま流すから

(liquid splatters)

犯人とのドライブを味わって

Whoa.

進んで

Thoughts?

でも…

- Probably less catalyst.

まだだ　駐車場に行って

- Good call.

バレないさ

It means you know failure's part of the process.

道は分かる

It's how you learn, and thinking this way

そう

makes you a better soccer player, or piano practicer

道は分かる

because you're resilient and you keep tweaking and trying

あの駐車場？

until you get it right.

他にもある

Or, you can just come up with a totally different solution.

通り沿いにあと２つ

(piano playing rapidly)

もう１つ欲しい

Because if you think like an engineer,

ごめん

you think differently,

漏らした？

and that unlocks creative new ways to have fun,

違う

and that's exactly why I created CrunchLabs,

臭いけど

where you get a super fun toy

におうな

that gets delivered to your porch every month.

何だ？

- Thanks, Mark Rober.

後ろが臭い

- You're gonna love that one, Sarah.

何なんだ

See you next month.

漏らした？

And then you put it together with me

いいから行って

as I teach you all the juicy physics that make 'em work.

用心してよ

So if you wanna train your brain,

別の車を

to see the world in a whole new light

そのまま待て

while having a ton of fun at the same time.

よし

(liquids exploding)

早く

Just go to CrunchLabs.com right now and reserve yours.

こっちだ

You nailed it, Gabe.

前に寄せて

Outta the gate, it was pretty clear

床を見て

if our goal was to find out

ダメ

who was behind all these car break-ins,

取ったぞ

they were gonna do everything in their power

開けてくれ

to not be found out.

渡して

(glass shatters)

ゲットした

But the advantage of teaming up

前に乗りな　早く

with an 18 time Emmy award-winning investigative journalist,

待って

is that when one of our eight cameras

早く乗れ

catches these guys nearly causing an accident,

中に戻って

we can play it back so Dan can run their license plate,

前に乗りな

which must be precisely why

分かったから

they'd removed their license plate.

なぜ後ろに？

Thankfully, on our third break-in, our luck improved.

彼を前に乗せる

And this time, we struck pay dirt

急いで

because once Dan ran the license plate,

前に乗りな

he made a shocking discovery.

ドアを開けて

Turns out, this car belonged to a longtime

心配ない

SF State College professor who also sits on the board

出して

of a prestigious Oakland Charter School,

よし

and so like any good investigative journalist,

次を探そう

Dan found his home address and showed up to confront him,

前の車の所に…

except he turned out to be a really nice guy who informed us

今のは？　何の音だ？

that his license plate was stolen from his car

15　14　13　12　11…

a few weeks prior.

出せ

And what Dan would eventually learn

８　７　６…

on nearly all the other license plates

意外にも半数以上が 車以外で盗みに来た

he would run over the course of our operation,

それぞれの手口があったよ

is that not only do the thieves commonly drive around

この犯人はリュックを狙ってる

with stolen license plates.

でも人目につくから

- [Thief] We got Georgia plates.

バスで隠れた瞬間 犯行に及んだ

- [Mark] But they tend to steal

この男は作業員のベスト姿で

from a similar color and model as their own vehicle

歩いてきた

to avoid an obvious mismatch.

すぐ自分の車に戻り

So the car thieves showed that they could handle our cameras

中身を確認する手口らしい

and investigative techniques, but now the question was

いつもは成功するんだろうが

how would they handle a little bit of harmless glitter?

今回は通用しなかったね

Spoiler alert, not very well.

15　14　13…

- [Thief] A safe?

結局リュックは捨てた

(beep) this ain't no (beep) safe.

キラキラを盗んだだけだ

This is like a bomb or something.

犯人の共通点は窓を割る素早さ

- [Thief] That looks like a tracker, yo.

どの窓も強化ガラスだから

Oh, it's on.

割るにはコツがいる

Oh, that's a tracker, T.

強化ガラスは工学技術の結晶だ

Come on, T.

割れにくい上に

Y'all see that's a tracker.

割れても粉々になりケガしにくい

Throw that (beep) dude.

でも弱点がある

- [T] I'm trying to, man.

点での衝撃にかなり弱いんだ

- [Thief] Dumb (beep), throw that (beep) out right here.

この通りサッカーボールも

- [Automated Voice] Five, four, three, two.

野球ボールもスパナも平気

(glass shatters)

でも点火プラグから取り出した 鋭くて固い部品は？

- [Mark] Notice how the first thing he does

窓の１点に衝撃を受けるから

is check the trunk by pulling down the seat,

すぐに割れる

trying to unsuccessfully steal our strapped down battery.

だから犯人はこんな工具を持ってる

This is pretty common for them to do,

先端がセラミックや鋼製で

and it's why leaving valuables in your trunk

軽い力で割れる

isn't really a great option.

バッテリーの不具合で ピエロは不発だったけど

(fart spray whirring)

ガラスに手こずる様子が撮れた

- [Automated Voice] 14, 13, 12.

荷物が目の前にあるのに

- [Mark] In the end, he changes his mind,

手に入れられず
