Window pass-through for microphone cables

I cut down a pool noodle (a long foam floatation toy for swimming pools) to serve as a window pass-through for the birdfeeder microphones. The foam cuts easily with a pocket knife and does a decent job of keeping out the last cold drafts of late winter, though I still take it out at night. A 2-inch deep slice at the halfway point is enough to pass the microphone cable through without compromising the window seal.
