A lightbulb in a firehouse in Livermore, CA, has been burning continuously since 1901. Unofficial keeper of the bulb, retired firefighter Tom Bramell reckons its longevity is down to old-fashioned craftsmanship.
"I believe the bulb has stayed alive so many years because the makers gave it a perfect seal, so no air gets inside the bulb to help disintegrate the carbon filament. This bulb operates in a vacuum and it doesn't burn hot. That's the secret." [Gizmodo]
