Hi, Pastor John;
I had a little life lesson the other day.
I found a valve stem cap that goes on a tire valve stem in my driveway. I looked on our Jeep and saw a cap was missing. I picked it up and screwed it back on. Later that afternoon, Judy drove it and called me that her tire was going flat and was driving straight back home. When she got home I saw the deflated tire and began the process of looking to see if there was anything obvious in the tire; screw, nail, etc.. I remembered that this was the same tire that had the missing valve stem cap and I unscrewed it and took it off. When I looked inside of the cap there were two tiny small rocks inside it near the top.
What had happened was that the added rocks in the cap pushed on the valve stem and when I screwed the cap on tight the rocks pressed on the stem, releasing air. I took the rocks out, inflated the tire, put the cap back on without the small rocks inside, and we have not had an issue since.
The lesson:
Make sure when you screw your cap on (your head) that there is nothing inside of it or you will be deflated. 🙂
