(glass shatters) - [Mark Rober] This guy
stole a package from my car, and a different guy stole
my package from a porch, and he's about to open it in his car. - Hello. (glitter bomb pops)
(record spins) - But what he doesn't realize is this is the fourth generation of a new and improved
custom-built bait package that is recording him on four phones and just released a pound of
the world's finest glitter. And he's about to discover
the other five new surprises for this year. Now I know what you're thinking. "Isn't it a bit excessive to spend the last four years of your
life trying to engineer the perfect revenge for porch pirates just 'cause someone stole
your package a few years ago and the police wouldn't
do anything about it?" And to that, I say no. And I'm gonna keep
doing it every Christmas until we can make a dent
in the 2 million packages that are stolen from porches every year. Plus, it's become such a
delightful engineering challenge for me to try and think
of all the different ways that we can upgrade it each year. And so with that, this
is Glitter Bomb 4.0. (car horn blaring) And that is the first of five
major upgrades this year. The lid shoots off as
soon as the package thief tries to open it. Our original design to pull
this off was a flywheel that spun up at irresponsibly
dangerous speeds. Then we lowered these
wheels to make contact with the flywheel, and they
shared an axle with the gear, which then used a rack and
pinion to launch the lid. But that was just way too over-engineered, even for my lofty
over-engineering standards. So that's when we pivoted
to a pneumatic system. But space is limited in the box, so we had to custom design
these aluminum pressure intakes with a little help from
my friends at Protolabs. They hooked me up and made
six of these in like two days, which was why they're
mine and your best friend for quick turnaround
machine parts like this. So the tank is filled with
air pressurized to 80 psi, and it's nestled here in the base. And then with the top half on, this hall effect sensor
right here can sense a magnet attached to the lid. So when the lid is lifted,
it triggers the air to rush into the pistons, and the boxing gloves do the rest. And the second major
improvement is this car horn, 'cause that just feels
like it's gonna make things more exciting for everyone. So when the lid first pops off- (car horn blaring) It actually sounds a
little bit more like that. And the third upgrade is the design of the glitter cup itself. This year, instead of
an open cup like this that spins all the
glitter out in one shot, we have a two-chambered cup like this, which means we get to fire the
glitter three separate times. So the way it works is you pour glitter in the top chamber here, and
it fills up both chambers. And when the cup spins, the
glitter in the lower chamber flies up and out the sides, but the glitter in the
upper chamber is trapped due to the centrifugal force. Then when the cup stops spinning, gravity basically loads
the next batch of glitter in the lower chamber for us. And so now of course it's ready to fly out on the next spin and so on. This totally passive solution means we get to save one of our
three glitter fires this year for when we get to the end of the out loud countdown sequence. - [Robotic Voice] One. (motor whirring) - [Mark] Now of course you'll still see the standard four phones
here that record the thief in all directions and upload
the footage to the cloud, as well as these four canisters filled with 20% more fart spray of legitimately the worst smell
you could possibly imagine, as demonstrated by the time I almost killed Macaulay Culkin himself. - (coughs) I can still smell it. (Macaulay chokes) - [Mark] The fourth upgrade is we have a dedicated onboard microphone
to record continuous audio once the package is stolen, and the fifth is this outer
casing is now made from this opaque machined acrylic. That means the entire glitter
bomb now glows much brighter to light up the scene if
it's opened in the dark, and it just looks really dope when the whole box pulses red and blue as we play the fake police scanner chatter a few minutes after being opened- (police radio chattering) - To further encourage the thief to get rid of the box
so we can recover it. And then the final upgrade for this year isn't actually on the glitter bomb itself. Last year we developed these doormats that would covertly charge
the box on these contacts so it would be at full battery
whenever it got stolen. And that was fantastic, but a lot of boxes were being taken at night, which was leading to footage
that just wasn't that great. So to solve for that this year, we designed these planter boxes, and when the sun goes
down, the side raises up, and they autonomously slide over to swallow up the glitter bomb, concealing it from any
would-be thieves in the night without the homeowner
needing to hassle with bringing it in and out every day. Then of course in the morning, the process reverses and
the box is ready to go. So now when the bad guy
comes sneaking by in the day and steals it off the porch, the batteries are all at 100% charge, and the box knows it's
no longer on the mat, so it starts recording and
uploading footage to the cloud, in addition to texting
us that it's been stolen and sending GPS location updates. And so if you compare
glitter bomb 1.0 through 4.0, you can really see the design evolution. And while my lawyers have
already made it very clear that I am not allowed to sell this, if I did, it might look
something like this. - [Announcer] Glitter Bomb 4.0 is our most advanced glitter bomb ever. Beautiful, complex, yet simple. A sleek and porch-informed design, now includes a car horn
from a Toyota Corolla and 20% more fart spray. A completely redesigned
multi-spray glitter cup with a pound of our finest
biodegradable glitter means your porch pirate
will remember this moment for a very long time, but especially in direct sunlight. Oh, and there is one more thing. Introducing the world's
first self-launching lid. (epic orchestral music) Glitter Bomb 4.0. (epic orchestral music) Because sometimes revenge is
a dish best served fabulously. (epic orchestral music) - So there it is. And while you can't buy Glitter Bomb 4.0, if you wanna support
more efforts like this, you can rock this stylish wire frame Glitter Bomb hoodie here, or we've also got this cool
retro pop art version for 4.0 with the boxing gloves, available, of course,
only at markrober.com. And so now all that was left to do was to put it out on porches
all across America and wait. And we didn't have to wait long. (playful music) Wait a sec. Is that who I think it is? And sure enough, Fort Knuts
had run out of walnuts, so instead of trying to make
an honest squirrel's living, Fat Gus had apparently
turned to a life of crime. And speaking of which, I'd
like to quickly point out that whether squirrels are
stealing your bird seeds so you build them an obstacle course, or humans are stealing your packages so you go full "Home Alone," the beauty about being an engineer is you can come up with clever solutions for your real-life challenges. (bell dings) It's like a superpower, but
a superpower you can learn, and I'd love to see other
people catch that spark. Which is why a few times a year I teach a month-long
creative engineering course, and enrollment for the
New Year's session is open starting right now. Over the course of a month, you're gonna watch me design and create three builds from scratch. But the best part is I'm gonna
guide you through finishing three creative builds of your own. So whether you're a complete beginner or an experienced engineer, the class has been designed
to meet you wherever you're at and level up your skills. Just go to monthly.com/markrober, or use the link in the video description, then go sign up as a New
Year's resolution goal, and let's hang out making some cool stuff. And now for the sparkly karma. (color bar beeps) (car horn blares) (motor whirring) (cartoon voice laughs) (motor whirring) So he hides it under some clothes, and a few minutes later
he brings in a consultant. (beep) - [Thief 1] It's a tracking device! - [Thief 2] Oh, no, no, no, no! - [Thief 1] And it smells like (beep). - [Thief 2] What do we do? What do we do? What do we do? What do we do? (motor whirring) (color bar beeps) (car horn blares) (motor whirring) - [Gangster] Keep the
change, you filthy animal. - [Mark] This guy wins the award for our most contemplative thief ever. (motor whirring) I've sped this footage up to double time. So we help to make up his mind with a third round of glitter, fart spray, and then the countdown. (motor whirring) (motor whirring) - [Robotic Voice] 15, 14- (color bar beeps) - [Mark] And as if stealing a glitter bomb wasn't a bad enough choice already, this guy doubles down and
decides to open it in his car. (motor whirring) (cartoon voice laughs) - [Thief] (beep). (beep), man. (motor whirring) (car horn blares) (motor whirring) (motor whirring) - [Robotic Voice] Fifteen, fourteen. Three, two, one. (package clatters) - [Mark] And it's worth
mentioning, of course, we have to make multiple glitter bombs, because sometimes they do take a beating. (color bar beeps)
(cartoon voice laughs) And yet they battle through
the pain like champs. (motor whirring) (color bar beeps) - [Thief 1] Look what I found! - [Thief 2] Did they see you take it? - [Thief 1] Nobody saw me. - [Thief 2] Like Harry and Marv. - [Mark] And they're
referring to our dead giveaway shipping label here, with Harry
and Marv on Wet Bandit Way. - [Thief 1] I feel bad, but I
really wanna open it. (laughs) - [Thief 2] I say you flip a coin. Heads you keep it. - [Mark] And apparently they landed heads, 'cause a few hours later, this happened. (car horn blares) (motor whirring) (cartoon voice laughs) - [Thief 1] What the (beep)? (motor whirring) (color bar beeps) - [Mark] This guy stole it and took it straight to a pawn shop to
try and negotiate a deal. - [Thief] 500. - [Pawnbroker] No, I told you 400. - [Thief] No, give me one
more hundred and we're good. - No.
- One more hundred. This thing is brand new, (beep). Come on. - [Pawnbroker] The wrapping
looks kind of weird. - [Thief] No, they're 2021. - [Pawnbroker] Let me open it and see if it's just in there first. - [Thief] One more hundred, (beep). One more hundred.
- Can I open it? - [Thief] Yeah, go ahead. (car horn blares) - What the (beep)? (motor whirring) (cartoon voice laughs) - [Mark] And this one's hilarious to me, 'cause if he wouldn't have got greedy, he could have walked out
of there with 400 bucks. - [Woman] It's a bomb. Yeah, yeah. Put it outside! (motor whirring) - [Robotic Voice] Fifteen, fourteen- - [Mark] And instead, he gets zero dollars and a bedazzled jacket. - [Robotic Voice] Detonation imminent. (color bar beeps) - [Thief 1] Oh my God, look it. (car horn blaring) (motor whirring) (cartoon voice laughs) - [Thief 2] Maybe they
put a thing on there so it went off. - [Thief 1] Did you see and hear that? (motor whirring) - [Thief 2] Put it back down. - [Thief 1] Really? - [Thief 2] Each time,
more (beep) comes out. - [Thief 1] It stinks too. - [Thief 2] Oh (beep), babe. Look at how full it is. (motor whirring) (motor whirring) (color bar beeps) (car horn blares) (motor whirring) (cartoon voice laughs) - Oh. (laughs) It's a trick. Someone fooled you. (motor whirring) - Oh! Ugh, it stinks! - Move. - [Woman] Go throw it away. - Oh, (beep). Smells like (beep). No! (motor whirring) (motor whirring) - [Mark] They eventually threw it away, and then went the extra
mile to help us rinse off all the glitter. (speaker screeches) Followed up with a light dusting. (broom thuds) (broom thuds) (color bar beeps) Last year, if you might recall,
we went up to San Francisco, a.k.a. the car break-in
capital of the world, and got a glitter bomb taken
in a matter of minutes. And while we never got them
to actually open the box, it did have an interesting conclusion. - [Thief] I could bang it. I could bang- (alarm blaring) (static crackles)
(color bar beeps) - [Mark] So this year,
naturally, we went back, and at the end of day
one, we had no takers. But then we stopped for like two minutes to get some snacks for the trip home, and when we came back
to the car, we saw this. They took the backpack with the GoPros but left the freaking glitter bomb. So now it was definitely on. So we went back to that
exact spot the next day, and within 10 minutes, this happened. (window shatters) (window shatters) And you could see here
just how quickly they work. - [Thief 1] Put that in the back, bro. - [Mark] You can literally hear them doing another smash and grab here, not four minutes after
they smashed our window. - [Thief 1] Come on, come
on, come on, come on! (beep), hurry up! Let's go!
- Yo, my car! Yo, what the (beep)?! Yo, (beep)! - [Mark] And unfortunately,
in all the jostling of stolen goods, the glitter
bomb had a false trigger- (car horn blares) (motor whirring) - [Thief 1] What was that? - [Mark] And they were onto us. - [Thief 2] That (beep)
has a light, (beep)! - [Thief 1] What you talking about, boss? - [Thief 2] Look, (beep). Yo, what the (beep) is that? Throw that out, baby. - [Thief 1] Hell nah. - So if we're keeping track at home, that's car thieves with three
points and me with zero, without a single ounce
of glitter being fired. Now I'm not proud of that, but there is a silver lining here, because the police rolled up
on us after this break-in, and let's just say they
are both familiar with, and fans of, the work being done here. In fact, they were
actually tracking the guys that smashed our window,
but then they lost them. So next year I'll be
joining forces with them in some capacity, and I'm
given a Mark Rober guarantee that I'm gonna get some
points on the board, and perhaps uncover how these
guys run their whole operation in the process. So make sure you're subscribed
if you don't wanna miss that. But it wasn't just the
police who'd heard about the glitter bomb this year. Just like before, we also
put some glitter bombs by a few group mailboxes, and I'm happy to report the
overwhelming majority of people do the right thing and
either don't take it or even go out of their
way like this nice lady. In fact, they were stolen
approximately half as often as last year, so either people are getting more honest, or perhaps, I don't know, enough people have seen these videos that it's the devastating power of glitter that's encouraging more civil behavior. And I'll just leave you
with two pieces of evidence that kind of seem to
support this working theory. (color bar beeps) - [Thief 1] I was lucky. That's a lucky steal right there, man. Best that money can buy. (car horn blares) - [Thief 2] Oh, (beep). (motor whirring) Oh, you son of a (beep). - [Thief 1] Oh, it's one of those gifts? - [Thief 2] Oh, wow. I seen that on TV, man. - [Thief 1] What's it do? - [Thief 2] Put that top back on. - [Thief 1] Why? (motor whirring) - [Thief 2] The glitter
that he showed on TV was that sticky kind. That's what you get for
taking people's stuff from in front of their house. God, right in my house. (beep) That thing has a tracer on it too. The cops are gonna be right outside. (color bar beeps) - [Thief] Then I'm wondering if it's one of those (beep) package thief things that spay out fart glitter. If this thing is gonna start talking and five, four, three, two, one. (car horn blares)
Oh my god! It is! (motor whirring) - [Mark] So just don't steal
packages, 'cause it's not nice. But if you do need some extra incentive, just know you might be opening
next year's glitter bomb. - [Thief] It is one of
those glitter bombs. And it has fart smell and everything. - [Mark] And trust me, you
don't wanna meet version 5.0. (motor whirring) (tense music)
