First let me say that we have a phenomenon at our house that is probably true in most homes. Occasionally we either have a kitchen container without a lid, or a lid that doesn't fit any of our containers. I am speaking mostly about those containers that we use for leftovers.
Now here is where what I learned in high school comes in.
Since I had a glass container without a lid but I still wanted to use it and store it for a few hours in the refrigerator, I placed another glass container (this one had it's lid) right on top as a substitute lid. It sort of sank a little into the under container.
What I learned in high school in physics class is that things expand when warm and contract when cold. This was important in this case because the glass container that was being used as a substitute lid was still warm. So what I learned in high school finally had a practical use. I knew that if I placed this warm glass container on top of a cold glass contain I would not need to worry about it getting stuck because if anything it would contract as it cooled.
Now the sad thing is that this is the first time I can recall using something that I learned in my high school physics class in a practical way.

Dogwood
Yesterday it was necessary to do some adjustments on our granddaughter's outfit. The skirt and shorts needed cinched in a little at the waste and the hook and eye closer was replaced on the top with a permanently sew together button. The opening is still large enough for her to put her head through and she won't have to fuss with the closer. We added a large eyelet ruffle and let out the hem of the top also. She seems to be shooting up through the middle right now. She really gave the shorts outfit a workout at her birthday party. It seemed to survive!
This afternoon the collision theory was in effect. A tractor with a wide load and a van met right where one of us was walking. There were no other vehicles in sight at the time.
