How can I pull off a classic office desk prank with the Annoyatron?

The Annoyatron turns your boring office into a comedy goldmine with its six different annoying sounds. This tiny device fits perfectly under desks and inside desktop computers for maximum chaos.
- Tape the device under your target’s desk drawer – The compact size makes it invisible while the 15 kHz mosquito tone drives them crazy during quiet work moments.
- Hide it inside their desktop computer case – Open the side panel and secure it with double-sided tape near the power supply for amplified confusion.
- Place it behind their monitor stand – The cricket sounds and electronic beeps will seem to come from their screen, making troubleshooting impossible.
- Stick it under their keyboard tray – Use the volume control knob to start low and gradually increase the annoyance over several days.
- Mount it inside their desk lamp base – The doorbell sound will make them think someone needs help while they’re focused on work.
- Secure it to the underside of their chair – Every movement triggers different sounds as the device alternates between its six noise options daily.
- Hide it in their desk phone base – The 12 kHz electronic noise mimics phone problems, causing endless IT support calls.
- Place it behind their filing cabinet – This location maintains the prank for several weeks with discreet battery changes when they’re away from their workspace.
Where is the best spot to hide the Annoyatron in a drawer?
Drawers make perfect hiding spots for the Annoyatron due to its small size, which makes detection nearly impossible. Choose a drawer that rarely gets opened, like the bottom desk drawer filled with old supplies or the kitchen junk drawer.
Attach your device using tape or a magnet, depending on the drawer’s material. Place it toward the back corner where it blends with other electronic items commonly found in office spaces.
This positioning takes advantage of the device’s low power design and random sound intervals.
The cricket noise setting works exceptionally well in drawer pranks, unlike under-desk placements where sounds get muffled. Your target will hear mysterious chirping but struggle to pinpoint the exact location.
The Annoyatron’s impressive battery life supports long-term pranks, even in confined spaces. Smart placement near a resistor or old breadboard from previous projects helps camouflage the device.
The random timing feature drives people crazy as they open and close drawers frantically searching for the source.
The best pranks are the ones that make people question their own sanity, and a well-hidden Annoyatron does exactly that.
How do I tuck the Annoyatron behind a picture frame for a prank?
Picture frames make perfect hiding spots for your Annoyatron device. The thin and compact design fits snugly behind most frames without detection.
- Choose a frame that sits at least two inches away from the wall to create enough space for the device placement.
- Set the volume control to its lowest setting so the beeping or cricket sounds blend with typical office background noise.
- Tape the lightweight Annoyatron to the back of the frame using double-sided adhesive strips for secure attachment.
- Position the device near the top corner of the frame where it stays hidden from casual viewing angles.
- Test the sound output before final placement to ensure the alternating sounds create confusion without being too obvious.
- Select frames in high-traffic areas where people spend time but rarely inspect wall decorations closely.
- The battery lasts several weeks in this location, making it a true “set it and forget it” prank setup.
- Place the device behind frames in conference rooms or cubicles where the sounds will drive coworkers crazy during quiet moments.
- Avoid frames that people frequently adjust or move, as this increases the risk of discovery and device falling.
What are some fun ways to use the Annoyatron in a car prank?
Car pranks with the Annoyatron create endless entertainment for tech-savvy pranksters. This tiny device costs just $5.39 plus $2.00 shipping and delivers weeks of battery-powered chaos in vehicles.
- Hide under the driver’s seat – Slip the device beneath the seat cushion where it stays hidden but produces maximum acoustic impact. The confined space amplifies every beep and chirp.
- Attach to metal surfaces with the built-in magnet – Stick it under the dashboard or behind the glove compartment door. Metal surfaces provide secure mounting points that keep the device stable.
- Place inside the glove compartment – Tuck it behind registration papers or the owner’s manual. Sounds echo perfectly in this enclosed space, making location nearly impossible.
- Mount behind air vents – Use the magnetic feature to attach it to ductwork behind dashboard vents. Airflow carries the random beeps throughout the entire cabin.
- Hide in door panels – Slip it into the storage pocket of car doors. The device stays concealed while delivering high-pitched cricket sounds that drive passengers crazy.
- Secure under the spare tire – For long-term pranks, place it in the trunk area near the spare tire. The battery-powered design operates for several days in this location.
- Attach to the undercarriage – Use the magnet to stick it to metal components under the vehicle. This creates mysterious sounds that seem to come from the engine bay.
- Place in cup holders – Drop it into unused cup holders and cover with napkins or small items. The compact form factor fits perfectly in these spaces.
How can I place the Annoyatron underneath a couch for a surprise?
Moving from car pranks to indoor furniture pranks opens up a whole new world of possibilities. The couch placement strategy ranks among the most effective indoor pranking techniques for maximum confusion.
- Choose the right Annoyatron color (white, blue, or black) to match your couch’s underside for better camouflage and stealth operation.
- Use the embedded magnet feature to attach the device securely to metal couch springs or frame components underneath the furniture.
- Set the volume to low settings to make detection harder while still producing audible random beeps or cricket sounds.
- Position the device near the center of the couch where people sit most often for maximum psychological impact.
- Test the sound projection before final placement to ensure the beeps create confusion about the source location.
- Take advantage of the thin design by sliding the Annoyatron between cushion gaps if magnetic attachment isn’t possible.
- Set the device to cricket sound mode for a more natural audio experience that mimics real insects hiding in furniture.
- Place multiple units under different furniture pieces for a coordinated prank campaign that costs only $5.12 per device.
- Schedule the prank during peak TV watching hours for maximum audience exposure and entertainment value.
What’s the best way to hide the Annoyatron in a backpack or purse?
The Annoyatron’s compact size makes it perfect for stealth operations in bags and purses. Smart placement turns any ordinary bag into a prank delivery system that drives victims crazy.
- Choose rarely accessed compartments – Target side pockets, inner zippered sections, or small fabric pouches that owners check infrequently. The device stays hidden longer in spots people forget about.
- Secure with tape or magnets – Attach the lightweight Annoyatron to prevent rattling around inside the bag. Strong adhesive tape works on fabric surfaces, while small magnets grip metal zippers.
- Bury under clothing layers – Place the device beneath sweaters, jackets, or other soft items to muffle sound output. This disguises the noise source and makes detection nearly impossible.
- Target laptop compartments – Hide the Annoyatron in padded computer sleeves where thick fabric dampens sounds. Most people rarely dig deep into these protected areas during normal use.
- Use accessory pockets strategically – Small makeup bags, phone cases, or sunglasses compartments provide perfect concealment spots. The random interval sounds confuse bag owners about the exact location.
- Position near electronics – Place the device close to phones, tablets, or other gadgets that make occasional noises. This creates false leads and extends the prank duration significantly.
- Exploit purse organization systems – Target card slots, pen holders, or small divider sections in organized bags. These tight spaces keep the Annoyatron stable and well-hidden from casual searches.
- Consider weight distribution – The lightweight design means placement anywhere won’t affect bag balance or raise suspicion. Even small purse pockets can accommodate this tiny noise maker effectively.
How can I use the Annoyatron in a kitchen cabinet prank?
Kitchen cabinet pranks work best because the Annoyatron’s built-in magnet sticks perfectly to metal surfaces inside cabinets. This device creates maximum confusion since its three different tones make the source nearly impossible to trace.
- Attach the magnetic base to the inside metal frame of upper cabinets – The built-in magnet provides secure placement that won’t fall during normal cabinet use.
- Use the adhesive sticker option for wooden cabinet interiors – Stick it behind the back panel where dishes won’t knock it loose during daily kitchen activities.
- Hide the device between stacked plates or bowls – Its thin profile fits perfectly in tight spaces, making detection extremely difficult for frustrated victims.
- Place it inside spice racks or behind condiment bottles – The cramped space amplifies the sound while keeping the source completely hidden from view.
- Mount it on the underside of cabinet shelves – This position creates an echo effect that makes the three different tones sound like they’re coming from multiple locations.
- Position the device near the cabinet hinges – Sound travels through the metal hardware, creating confusion about whether noise comes from inside or outside the cabinet.
- Set it behind large appliances stored in cabinets – Blenders, mixers, and other kitchen gadgets provide excellent cover while the battery life ensures days of operation.
- Install it in corner cabinets where access is limited – These hard-to-reach spots guarantee your victim will struggle to locate the source, especially with the auto-off function creating intermittent sounds.
How do I place the Annoyatron in a closet to prank someone?
Closets create perfect hiding spots for the Annoyatron because their enclosed spaces amplify sound effects. The compact design makes placement simple while the random beeping blends with normal household sounds.
- Select shared closets or high-traffic areas – Target closets that multiple people use daily to maximize your victim count and create widespread confusion.
- Attach the device to clothing hangers – Clip or tape the Annoyatron to plastic hangers where it stays hidden among shirts and jackets.
- Tuck inside shoes for stealth placement – Place the device inside boots or sneakers that sit on closet floors, creating muffled but audible sounds.
- Mount on closet rods above eye level – Secure the Annoyatron to the top rod using small zip ties or adhesive strips for hard-to-find positioning.
- Hide among folded clothes on shelves – Bury the device between sweaters or linens where fabric dampens but doesn’t block the sound completely.
- Select devices in matching colors – Choose Annoyatrons that blend with closet interiors since market options range from $4.22 to $7.54 in various colors.
- Plan battery changes during off-hours – Replace batteries when closets aren’t being used to maintain your prank’s longevity without detection.
- Position near the back wall – Place the device against rear closet walls where sound bounces forward while staying concealed behind hanging clothes.
Now we’ll discuss creative outdoor pranking ideas with the Annoyatron.
What are clever ways to hide the Annoyatron in a ventilation duct?
Ventilation ducts offer the perfect hiding spot for your Annoyatron device. Opening ceiling panels gives you access to the entire duct system where sound travels throughout multiple rooms.
- Access ceiling tiles carefully and locate main air ducts that connect to several offices or rooms for maximum coverage.
- Tape the Annoyatron to the inside wall of the duct using strong adhesive, ensuring it won’t fall or rattle during air circulation.
- Choose ducts near return air vents where the device’s random sound intervals will echo through the entire building system.
- Position the unit close to vent openings but far enough inside to avoid detection during routine maintenance checks.
- Select battery-powered variants with extended life spans since retrieving the device from ducts requires significant effort and planning.
- Place multiple units in different duct sections to create widespread confusion, making the source nearly impossible to pinpoint.
- Test sound transmission before final placement by dropping small objects to hear which areas provide the best acoustic coverage.
- Mark your hiding location discreetly for future battery changes, as the prank can last several weeks without detection.
- Consider HVAC schedules and avoid placement during maintenance periods when technicians might discover your device accidentally.
Car pranks offer another exciting venue for Annoyatron deployment with unique challenges.
How can I use the Annoyatron in a bedroom for late-night pranking?
The Annoyatron 2.0 turns bedrooms into perfect prank zones with its mosquito tones and beeping sounds. Late-night pranks work best because targets feel confused and frustrated in their most private space.
- Hide the device under the bed frame near the headboard, where dust and shadows provide natural cover, making detection nearly impossible during sleepy searches.
- Place the Annoyatron inside nightstand drawers behind books or charging cables, ensuring the sound travels through the wood while staying concealed from quick glances.
- Set the volume low initially and increase it gradually over several nights to build psychological tension without immediate discovery.
- Program five-minute intervals between sounds to create unpredictable patterns that disrupt sleep cycles without becoming too obvious.
- Tape the device behind picture frames on bedroom walls where the sound bounces around the room, creating confusion about the source location.
- Change batteries discreetly during daytime hours when the target is away to maintain the prank for multiple nights without interruption.
- Position the Annoyatron near CMOS alarm clocks or electronic devices to mask the source among other bedroom gadgets and create audio camouflage.
- Use the compact form factor to slip the device between mattresses and box springs where body movement won’t dislodge it during sleep.
- Schedule activation times around typical bedtime routines when targets expect quiet environments, maximizing the surprise element and sleep disruption effects.

the story’s time line doesn’t add up, or better said is fiction. A couple of weeks go by, spring turns to summer, having to change the battery, using this toy for a month-all in a month?
Heck just using a wireless mouse with the dongle in someone else’s PC is a far better hoot and drives the intended target crazy much faster.
When the annoyatron 1.0 came out, I bought them from a website called Thinkgeek, and I bought a 3 pack bundle. Those just gave a random ‘beep’. I deployed the first one in the office in a well hidden area. I deployed the second one in an opposite side of the office to confuse everyone. The boss had the smoke detectors checked, time clock, door chime, even the wireless router. After 6 weeks, my downfall was to deploy the third one. I guess the boss had enough, and after everyone left, he stayed to do a hard search for the source of the noise. I hear tell he stayed until near 10:00 pm to find all three. He found them, but never found out who was responsable. While looking for a pencil to leave him a note, I found all three in his desk, so I took them. They worked great, never had a problem with the battery and well worth the cost. And best of all, no one figured who did it.I recommend up in a suspended ceiling or inside a desk behind a drawer.
