Alarm Clock in Wall Rings Every Day -for 13 Years

Jerry Lynn of Ross Township, Pennsylvania, had a great idea that turned bizarre. He tied a battery-powered alarm clock to a string and lowered it through a vent into a wall, in order to determine where he should install a cable outlet for his TV. The alarm was set to go off in a few minutes, and he would drill the hole near the sound, ensuring that a cable would have an unobstructed path. Surely there are better ways of doing that, but the plan seemed sound. Until the string broke. The clock fell too far down to be retrieved.

“As I was laying it down, all of a sudden I heard it go ‘thunk!’ as it came loose,” he said. “I thought, well, that’s not a real problem. You know it’s still going to go off. And it did.”

He couldn’t pull it back up, but figured, “Maybe, three-four months it’ll run out of battery. That was in September of 2004. It is still going off every day. And during daylight savings time it goes off at ten minutes ’til eight. And during standard time it goes off at ten minutes to seven at night.”

Clocks do not draw much power from a battery, but the longest I've had one last is six years. This one has been ringing daily for 13 years. I would have torn the wall apart by now. -via Boing Boing
