I freely admit to being a “scrounger”. I salvage, save, “preserve”, conserve etc. any number of things that otherwise would just go in the trash bin. Sometimes it works out unexpectedly.
The piece in the photo above is the rubber finger-grip off of an old gel-pen that got tossed out. I pull the grippies off figuring they might come in handy to put on the handle of some small tool or other, at some point in future time. I found this one hanging out in a bowl when I was doing a bit of cleanup just now.
A couple of weeks ago, I found some old brass, 45 cal. pistol casings and had played around with them, blowing across the top to see what kind of freebie peep-whistle they might make for emergency kits. Imagine my surprise when I put my finger over one end of this little piece of rubberized tubing and it emitted a piercing shriek… F# below middle C. It is as loud, and carrying as any emergency whistle I have ever seen.
Best of all, because it is of rubber, it will squish down flat and pack into a kit taking up much less room… and much more flexibly.
The bad news is: I pulled out several other grips I had saved and none of them produce any kind of clear note at all. Win some, lose some. I have no idea at all what kind of pen this might have come off of, but all the other grips are of a softer, more “silicone-gel”-like material. They are all too flimsy to produce a clear note. This one however is a champ. It’s going right into my kit.
Always look around, see what you might find. You never know what comes in handy for the most unusual application. That’s what your junk drawer is for…
