Detailed notes
## Background Published on YouTube by Mark Rober on December 16, 2022, this video showcases the fifth and nearly final iteration of his anti-theft glitter bomb series. In the description, Rober promotes his CrunchLabs Build Box subscription for the holidays and highlights a sponsor segment with T-Mobile, whose cellular network powered the bait packages.
## TL;DR Mark Rober chronicles five years of engineering anti-theft bait packages, culminating in Glitter Bomb 5.0 equipped with autonomous glitter-dispersing drones and a massive one-liter fart spray reservoir. Shifting focus to San Francisco's smash-and-grab epidemic, Rober designs specialized car-bait variants to retaliate against organized burglary crews who break rear quarter windows to scout vehicle trunks. After thieves initially ignore visible packages, the team repackages the payload into stealthy backpacks, successfully baiting active crews and remotely venting foul spray inside their getaway cars. The video concludes by reviewing the broader real-world impact of the project, including the shutdown of three international call-center operations, and promotes CrunchLabs engineering kits for kids.
## Atmosphere & style The presentation blends whimsical, festive holiday cheer with the meticulous precision of a high-stakes engineering lab. Rober's delivery is charismatic, upbeat, and playfully vindictive, adopting a classic 'Home Alone' energy that frames complex technical iteration as playful retribution. Tense stakeout footage gives way to explosive, comedic pandemonium as hidden cameras capture the bewildered, foul-smelling chaos unfolding inside thieves' cars and homes.

## Detailed walkthrough ### [00:00](https://www.youtube.com/watch?v=iWeu2dxHRDg&t=0s) The Origins and Evolution of the Glitter Bomb
The journey began five years earlier when two thieves stole a simple $6 package off Mark Rober's porch. After police refused to take action despite being handed video evidence, Rober decided to harness his engineering skills to retaliate. Mark recalls that “to avenge the theft, I was gonna have to use my engineering skills to go full 'Home Alone.'” What started as a personal quest ended up setting off a nationwide saga that exposed countless porch pirates and eventually contributed to the takedown of a $60 million international scam ring.
Over the years, the bait package underwent continuous engineering overhauls: - **Version 1.0:** Featured a spinning cup dispersing one pound of fine glitter, four hidden smartphones to record and upload video, and a single canister of fart spray designed to prompt the thief to ditch the package for retrieval. - **Version 2.0:** Doubled the fart spray payload, refined the scent formula (which famously left guest collaborator Macaulay Culkin coughing and gagging), switched exclusively to biodegradable glitter, and introduced a fake countdown timer paired with simulated police radio chatter. - **Version 3.0:** Upgraded to four canisters of fart spray, added a grab handle coated in ultra-sticky mousetrap glue, flashing police lights, and conductive charging pins hidden in an engineered doormat to keep the box powered indefinitely. To defeat thieves who quickly replaced the lid to cover the lenses, mechanical posts popped out passively once the lid was lifted, permanently preventing the box from closing. - **Version 4.0:** Fitted pneumatic pistons capped with boxing gloves to launch the lid straight up the moment it was touched. It also introduced an onboard car horn, a redesigned multi-chamber centrifugal cup offering three sequential glitter blasts, and a motorized, sliding faux planter box that automatically concealed packages overnight to restrict thefts to optimal daylight hours.

[03:03](https://www.youtube.com/watch?v=iWeu2dxHRDg&t=183s) Engineering Glitter Bomb 5.0 and the Car Bait Sister Box
For the fifth and final iteration, Glitter Bomb 5.0, Rober went all out despite acknowledging the classic engineering risk: “In engineering, if something is working well enough, conventional wisdom states you should basically change nothing but pretend like you changed a lot.” Rather than relying on small aerosol cans totaling 20 milliliters, the new design incorporated a massive one-liter reservoir—50 times more fart spray than the previous year. A continuous peristaltic pump forced the liquid through two high-pressure nozzles. When tested with an air-particulate sensor inside an enclosed chamber, the previous version registered 250 particulate units per liter, while version 5.0 topped out at 750, delivering an aroma three times as potent that degraded room air quality at a rate of one liter per minute.
To accommodate the larger fluid tank, the chassis was widened, creating room for a custom printed circuit board (PCB) that managed power, system triggers, and synchronized data transmission across four smartphones running on T-Mobile's high-speed network. The centerpiece of the porch version was a fleet of hacked, autonomous mini-drones. Rewritten firmware allowed the drones to wake up and take flight as soon as trapdoors dropped when the box was opened. Equipped with proximity sensors, the drones actively dodged incoming hands and meandered through rooms, showering fine glitter throughout the thief's living quarters.
Because the San Francisco Bay Area is known as the smash-and-grab capital of the world, Rober also built a specialized sister unit tailored for car break-ins. Because letting drones loose inside a moving getaway vehicle posed major safety hazards, the vehicle variant omitted drones. Instead, it was engineered to trigger remotely via SMS, venting the high-potency fart spray without needing the box to open. Moments before the spray engaged, a motorized 360-degree camera elevated out of the chassis to record the perpetrators, featuring an automated retraction system reminiscent of luxury car hood ornaments that retracted the camera into the armored shell if physical tampering was detected.
[06:08](https://www.youtube.com/watch?v=iWeu2dxHRDg&t=368s) Deployments, Dumps, and Family Dynamics
After roughly ten months of design and lab testing, the traps were planted on neighborhood porches and inside parked cars. The first car deployment was quickly targeted by thieves who shattered the vehicle glass, grabbed the package, and brought it to a residence. As the thieves examined what they believed was a valuable retail item, the box suddenly activated its car alarm, flashed strobes, ran through its countdown sequence, and fired the persistent fart spray nozzles. Realizing the device was an inescapable sensory nightmare, the thieves solved the issue by dumping the spraying box into their neighbor's yard.
Another box was snatched from a porch and transported home by a couple who hesitated to bring it indoors right away. In recorded audio, the woman noted that their neighbor had security cameras, cautiously telling her partner, “Can we just leave it in the car for now?” and insisting, “I'm not saying that I did anything wrong.” They eventually brought the box inside, where their kids immediately presumed the contents were an expensive virtual reality headset worth around $400. One child urged, “Keep it. Keep it. They can get another one,” while debating whether to keep or return it. Once they pried the lid open, the device triggered its piercing alarm and unleashed the foul stench. Pandemonium broke out as one child yelled, “They were lying!” followed by panicked cries of “Mom, I think it is a bomb,” prompting the mother to scream to get it out of the house. Though the thieves ultimately destroyed the physical box and tore out the phones, the footage survived thanks to rapid cloud backup over cellular data.
To track long-term integrity trends alongside porch traps, Rober also left bait packages near communal neighborhood mailboxes. This enabled the team to monitor how many good Samaritans would voluntarily call the contact number listed on the parcel versus those who simply walked away with it, including instances where adults handed the bait directly to their children as an impromptu gift.
[08:58](https://www.youtube.com/watch?v=iWeu2dxHRDg&t=538s) Foiled Porch Pirates and the San Francisco Car Epidemic
The glitter bomb trap continues to catch porch thieves off guard as the system counts down, triggering an ear-piercing siren and color bars. Inside a house, the sudden chaos sends a thief running into a panic, yelling out to family, “Mom! I think it's a scam! It's a (beep) scam. I knew it.” A woman wonders aloud what the device could possibly be, prompting the exasperated thief to realize who was behind it: “Yeah, (beep) this is a YouTuber. They do this to scam people.” Once the automated computer voice announces that activation is complete and the recovery sequence has been initiated, Mark Rober shifts focus to an entirely different arena of theft: car break-ins.
San Francisco has earned an infamous reputation as the car-breaking capital of the world, averaging roughly 73 smash-and-grabs every day. Things have gotten so extreme that residents have resorted to leaving their car doors wide open, practically inviting prowlers to see for themselves that no valuables are inside just to spare their windows from being smashed. While Rober had experimented with bait cars over the previous two years, thieves never opened the boxes inside the vehicles; the team had to settle for triggering a simple alarm so the crooks would chuck them out of the moving car. Research revealed that car burglaries operate within organized fencing rings. Crews canvas neighborhoods in teams and promptly deliver their haul to a middleman who pays cash for high-value tech like laptops. The heartbreaking consequence is that personal, irreplaceable items—passports, photographs, plane tickets—hold zero resale value for fences and simply get tossed straight into city dumpsters.

[10:48](https://www.youtube.com/watch?v=iWeu2dxHRDg&t=648s) Adapting to Thief Behavior and the Trunk Trap
Armed with the knowledge that thieves never unpack boxes inside the car, Rober modified the bait hardware. The fart spray nozzles were repositioned to poke straight through the box lid, allowing deployment even if the package remained sealed on the floorboards or back seat. Once the bottom proximity sensor fired, the box texted the team, allowing them to track the car via GPS and remotely send a command to raise the internal camera and vent concentrated foul odor for two solid minutes. Setting up their first stakeout with the box clearly visible inside a parked car, the team watched three separate vehicles—first a black car, then a beige car, and finally a white car—pull alongside. Each time, a scout hopped out, examined the box through the window, and walked away without touching it.
Rober reasoned that the bulky footprint of the original box looked too suspicious. The team gutted the internal components and condensed them into a significantly smaller package that maintained all the same functionality. Returning to the streets the next day, a thief finally smashed the window, yet drove away without taking the parcel. Reviewing the interior camera footage revealed an eye-opening revelation: the burglar never wanted the box in the first place. Instead, breaking the small rear quarter glass was solely done to reach inside, drop the rear seatback down, and scout the hidden trunk compartment. Rober emphasizes this crucial takeaway:
> “The reason they break these little windows so often but it seems like nothing is missing is because they're pulling down the seat to quickly check what's hidden from view in the trunk.”
- San Francisco averages roughly 73 car break-ins per day. - Leaving luggage hidden out of sight in a vehicle trunk does not protect it, as thieves break the rear quarter-glass specifically to drop the rear seats and peer inside. - High-value electronics are rapidly fenced for cash, while irreplaceable personal items like passports and family photos are routinely thrown into the trash.
[12:45](https://www.youtube.com/watch?v=iWeu2dxHRDg&t=765s) The Backpack Redesign and Double Hit
Faced with savvy thieves who recognized that shiny bait boxes meant trouble, Rober leaned into the core principle of engineering: “And as an engineer, I never claim to have all the answers, but I know the process to get to all the answers, and that's trying and failing and tweaking over and over again.” To counter their tactics, the team abandoned boxes entirely and engineered a micro version packed inside a typical backpack. The tight form factor required major trade-offs: the camera had to be eliminated, and the fart spray reservoir was reduced to a custom flexible pouch. To verify potency, they bench-tested the spray on an outdoor chair; days later, the chair still reeked so badly it was uninhabitable.
```mermaid flowchart LR accTitle: Glitter Bomb Evolution for Car Thieves accDescr: Evolution of bait packaging from large car boxes to concealed backpacks. subgraph Iteration["Design Iterations"] A["Original Large Box\n(Spotted and ignored)"] --> B["Compact Box\n(Ignored; seats dropped)"] B --> C["Backpack Stealth Rig\n(No camera, pouch reservoir)"] end subgraph Result["Street Deployment"] C --> D["Target Hits in 5 Minutes"] D --> E["Remote Deployment via SMS"] end ```
The team deployed two bait cars, each with a backpack sitting inside, parked in separate locations across San Francisco. Within roughly five minutes of each other, both cars were hit. Comparing video footage from the earlier stakeout revealed that one of the culprits wore the exact same jacket, proving that organized crews run regular routes and actively hunt for unfamiliar visiting vehicles. The surveillance captured how effortlessly tempered car glass gives way when struck by a punch: while the thief appeared to casually push a gloved fist through the pane, the glove concealed a tiny ceramic shard or hardened steel point designed to concentrate force and shatter the glass safely and instantly.
- Tempered car windows resist blunt trauma but shatter instantly when struck by a concentrated point of hardened steel or ceramic. - Car burglary crews patrol predictable loops, making out-of-state and rental vehicles easy targets. - Miniaturizing the trap into a backpack meant sacrificing live interior video and replacing the rigid spray bottle with an improvised pouch.
[14:43](https://www.youtube.com/watch?v=iWeu2dxHRDg&t=883s) Operation Air Freshener and Real-World Impact
Both stolen backpacks checked in via cellular signal, pinging their live GPS coordinates as the thieves drove around city streets, hitting additional cars along their path. One brazen crew was recorded bragging in their getaway car about an earlier score, boasting, “They had two big (beep) suitcases, and they let me steal their stuff.” After tracking both getaways for roughly ten minutes, Rober's team sent the remote SMS trigger to initiate “Operation Air Freshener.” In the first vehicle, the internal microphone was nestled right next to the electric pump inside the small housing, muffling the voices. However, roughly 90 seconds after the continuous spray began, the thieves could no longer stand the rancid stench, frantically located the bag by smell, and hurled it out the car window onto the pavement.
In the second vehicle, the reaction was captured with clearer audio. The thieves began inspecting their prize, remarking, “This is a weird (beeps) backpack,” before the chemical smell filled the cabin. Confusion turned to outright panic as they yelled, “What the (beeps) is that?” and “Look at it. I dunno what to do,” before tossing the offending bag out into the street just twenty seconds later.
Wrapping up five years of the glitter bomb project, Rober reflects on the broader trends: porch thefts have steadily dropped year over year while instances of Good Samaritans rescuing boxes have risen. Beyond deterring neighborhood thieves, community engagement produced massive real-world justice against organized cybercrime:
> “One thing that's not conjecture, however, is after so many of you actively shared our video where we infiltrated and glitter-bombed those three terrible scam call centers in India, it got the attention of some international law enforcement agencies, and from the press and because of your efforts, those three centers that had each been in operation for more than a decade, doing upwards of $20 million a year, scamming the most vulnerable amongst us of their life savings, all got shut down, with their top officials arrested.”
