You are in a brightly lit room. There is one door that is locked. The only way to unlock it is to get fillament from a lightbulb. Away from the lightbulb is a pipe that is dripping water. Also close by is an air vent that is too small to crawl through. There is nothing else in the room and the lightbulb is too far away to grab. How do you escape the room.
(I didn't need to have you guess the fillament part, as it's already been explained in past riddles. The rest, however, you're on your own.
