How do you puncture a light bulb?

Answer

With great care. The standard light bulb is comprised of a continuous glass housing. The only thing that goes through the glass are the two wires that provide the current pathways to the inside of the envelope where the filament is. To create a hole in a bulb requires a lot of patience, a lot of care and the use of some sort of abrasive tool to grind the hole. Though it might be possible to create a hole by actually drilling it, it is improbable that one could do it without ending up breaking the bulb. The glass isn't that thick, and because the surface is round, smooth and hard, it would be exceedingly difficult to get the drill bit to bite (start). A very small rotary abrasive bit in a dremel tool is probably the best bet. Eye protection is a MUST and hand protection is strongly recommended. Oh, and you are being warned up front: be very careful about what you do with your light bulb with the hole in it. Aiight?
