FUN delivery Bleepin' Battery Hidden Noise Maker Prank – Realistic Smoke Alarm Beep Gag for Office Prank Wars & April Fools

This hidden noise maker from FUN delivery produces a realistic low-battery smoke alarm chirp every 10 minutes, turning any quiet room into a harmless mystery. Stick it behind a picture frame, under a desk, or inside a drawer using the adhesive backing—then watch coworkers or family members search for the phantom beep. Designed for adults who enjoy playful mischief without damage or disruption, it runs on one included battery and has a simple on/off switch. No apps, no setup, just confusion and laughs.

What makes this prank device different from a real smoke detector?

The beep mimics the exact chirp of a dying smoke alarm, so people instinctively treat it as a maintenance issue rather than a prank. Each beep lasts a split second and repeats every 10 minutes—long enough to drive someone crazy trying to locate the source. The sound is convincing but not loud enough to be painful or alarming, keeping the joke harmless.

Where can you hide it?

• Behind a wall clock or framed photo
• Under an office chair or desk blotter
• Inside a ceiling vent or light fixture housing
• Taped to the back of a monitor or TV
• Inside a kitchen cabinet or drawer

The compact body (about the size of a standard key fob) and peel‑off adhesive backing let you attach it almost anywhere. Remove the adhesive liner, press it onto a clean surface, and flip the switch to start the prank.

How long does the battery last?

The device comes with one alkaline coin cell battery (typically CR2032). At one beep every 10 minutes, the battery can last several weeks to a couple of months depending on the specific cell. When the sound weakens, replace the battery easily via the small compartment on the back.

Is the sound loud enough to hear across a room?

Yes, the beep is designed to be audible in a typical office or bedroom environment. It’s not ear‑splitting but noticeable enough to make people stop and listen. The intermittent timing makes it especially tricky to track—by the time someone turns toward the noise, it’s already silent.

Perfect occasions for this gag gift

• Office prank wars and team bonding
• April Fools' Day surprises
• Secret Santa or white elephant exchanges
• Long‑term “slow burn” practical jokes
• Housewarming or dorm move‑in gifts

Because the device is harmless and doesn’t damage property, it suits both workplace and home environments. The confusion it causes usually leads to laughter once the victim discovers the source—or decides to pass the prank along.

Frequently asked questions about the Bleepin' Battery prank

Can you hear it through walls?

The sound is designed for indoor room‑level audibility. It may be faint through thick walls, so placing it in the target’s main space works best.

Is it safe for pets?

The beep is a short, low‑volume chirp—not a high‑pitched ultrasonic sound. While pets might notice it, they are unlikely to be distressed. Supervise initial use if you have sensitive animals.

Does it come with the battery installed?

Yes, a battery is pre‑installed with a plastic pull tab to prevent activation during shipping. Remove the tab to start the prank.

Can you turn it off after starting?

Yes, slide the on/off switch to the OFF position. The beeping stops immediately. You can turn it back on later for additional rounds.
