I’m not talking about lightness. I’m talking about the light bulb itself. I’m sure everybody is familiar with the squeaking noise produced by unscrewing of a light bulb that has been there for a while. Or worse, most of you met the situation where you try to unscrew a burnt light bulb and you’re stuck with only the glass part in your hand. What about the rest? How do you get it out of the socket? First of all, when it comes to electricity, never play. I don’t say you have to call a repairman for such a “huge” problem, but be safe. Switch off the power and it might be even safer to disable the fuse for the room, if you can access it and know which it is (If we’re talking about a fixture, unplugging it will do). Now, the rest I’ve read, but didn’t try. Don’t laugh, it is not a joke: grab a potato, push it into the socket and unscrew. The explanation is that the potato embeds into the metallic piece, just like the glass part did, so it’s a replacement. From here on, you get the idea. I don’t know why potato, probably because of it’s physical proprieties in raw form. Screw in>Replug>Turn on.

Wait! Before you screw in the new bulb, it’s a very good idea to lube up the thread with a tiny amount of Vaseline. It is a good conductor and a very good lubricant. This way you rid yourself of both the noise and the stuck in light bulb part. I don’t recommend other lubricants because I don’t know their properties. For your experimentation look for lubricants that are recommended for metals and are good electrical conductors. These two conditions are enough.
