Found in a park near my house, in Tulsa. Old weather gauge/equipment? A: I used to work on these, its a weather gauge station. The top part has a tipping bucket under a funnel and it transmits through radio every time it tips. Sometimes they have a pressure transducer running to a stream or river to calculate how much it has risen in a set amount of time.

What is this pink “dust” that keeps reappearing in the corners of my kitchen ceiling within a few hours of being cleaned? A: Clean it away and (lightly) tape a white printer paper over one angle of the corner. Do the spots reappear on the paper or on the wall underneath it? If it appears on the paper but not on the wall, it originates from the airflow. If it is growing from the wall it should first be visible on the wall underneath the paper, then possibly penetrate the office paper. If it really is coming through the wall and reappearing in a few hours you most likely have a problem behind it. Living things like bacteria or mold don’t grow that fast in room temperature/humidity if cleaned well. But might be a reservoir of something on the floor above that is seeping through.

Those metal structures, found near buildings in residential areas in Sweden. They are all slightly different, and I didn’t see them used by anyone.
