The Annoyatron Prank
As the name promises, the Annoyatron exists for exactly one purpose: to quietly, relentlessly annoy the heck out of your unsuspecting victim. It is a tiny electronic device that emits a short, high-pitched beep at random intervals – and because those intervals are unpredictable and the pitch is hard to locate, it turns a calm coworker or roommate into a hair-tearing detective within a day. It is one of the all-time great harmless pranks, and after years of recommending it, it is still our favorite slow-burn gag. Here is our full review.
What it is and why it is so funny
Picture the scene. You hear it – “BEEP!” Ten minutes later, that same faint chirp happens again. “BEEP!” Your brain starts itching: I need to find that thing. You set off on a frantic search, but the sound is going off at random – five minutes, then eight, then three. Each beep is short enough and high enough that you can never quite pin down where it is coming from. Soon your office or bedroom is a disheveled mess, drawers open, cushions on the floor, and anyone walking by can read the crazed look on your face. The anticipation is the real torture: waiting for the next beep eats you alive.
That psychological slow-burn is what makes the Annoyatron brilliant. It does not do anything to the victim – it just plants a tiny seed of “what is that noise?” and lets their own brain do all the work. It is completely harmless, which is exactly why it lands.
What you get
The device is impressively small – roughly the size of a couple of stacked coins – and it comes with its own battery good for weeks of chirping. Most versions have a magnet and a switch, and better ones let you pick the sound (a beep, a faint electronic whine, even an occasional “crickets” chirp) and the frequency so you can dial in maximum subtlety. They typically run around $10-$15, which is a lot of comedy per dollar. Check current options for the Annoyatron prank noise device.
Best places to hide an Annoyatron
Placement is everything. The goal is somewhere hard to reach and hard to pinpoint. Our tried-and-true spots:
- Taped up underneath a desk or beneath the lip of a drawer.
- Inside a ceiling tile or behind a wall-mounted monitor.
- Wedged in the back of a file cabinet – a classic that once forced a coworker to pull the entire cabinet out to find it.
- Sewn or tucked into a teddy bear or couch cushion.
- Behind books on a shelf, inside a potted plant, or above a ceiling light.
Use the built-in magnet or a strip of tape so it stays put, and pick a spot high up or awkwardly low – sound is hardest to locate when it comes from above or from a tight cavity. Got a coworker driving you crazy? A well-hidden Annoyatron will have them fiendishly, helplessly searching every corner of their cubicle while you keep a straight face.
Level up: film the reaction
Half the fun is watching the search unfold, so consider planting a small camera nearby. A discreet mini hidden camera lets you capture the meltdown and enjoy it forever. Here is one legend who did exactly that:
Who to use it on
The Annoyatron is best aimed at people who can take a joke and will laugh once you reveal it: the roommate, the coworker in the next cube, a sibling, a good-natured boss. Keep the reveal in mind – this is a prank you want to end with a laugh, not with someone genuinely rattled after a week of poor sleep, so do not hide it in a bedroom where it will wreck someone’s rest. If you love this kind of harmless-torment gag, it pairs beautifully with a speech jammer for a one-two punch, and it makes a perfect stowaway inside one of our not-so-discreet prank boxes. For a louder, grosser follow-up on the same victim, there is always Liquid Ass.
Mini pros and cons
- Pro: Totally harmless – it makes noise and nothing else.
- Pro: Weeks of battery life and adjustable sounds on better models.
- Pro: The slow-burn payoff is unbeatable, especially on camera.
- Con: Cheap models have a fixed sound and limited timing options.
- Con: Too effective on the wrong target can genuinely stress them out – place it thoughtfully.
FAQ
How long does an Annoyatron’s battery last?
Most run for weeks on the included coin battery, since each beep uses tiny amounts of power. That is plenty for a long-running prank, though it is smart to switch it off once your victim finally cracks the case.
Is the Annoyatron actually hard to find?
Yes – that is the entire design. The beeps are short, high-pitched, and randomly timed, which makes the human ear terrible at locating them. Hidden in a drawer, ceiling tile, or the back of a cabinet, it can survive days of searching.
Where should I not hide one?
Avoid bedrooms and anywhere it could disrupt sleep or safety-critical concentration, and skip shared or public spaces where a stranger might find it alarming. Keep it on friends and coworkers who will laugh at the reveal.
The Annoyatron earns its name and then some. It is cheap, harmless, endlessly funny, and requires almost no effort beyond hiding it well. Grab an Annoyatron, hide it somewhere devious, and let the beeping begin.
