[The Hat]

Yes, Mr. Hat, rubbing it in, of course.

On the contrary, you take a better photo than I, so it’s all compliments to you..

PeterBJ, you probably know that a lot of colored foods are acid-base indicators. Red cabbage does that, of course, and you can see the effect when you are washing dishes. As I recall, cranberry (tranebær) juice does that. I think I have also seen it in strongly colored fruit juices.

I have noticed that black currant s and blueberries also contain an indicator dye. I live in a hard water area and my tap water is alkaline. I have noticed a colour shift from red to blue when rinsing plates with black currant jam and similar.

But the pH dependent colour change of the Hydrangea seems to be more complicated than a simple acid-base indicator reaction. See this.

I would normally use Sulphate of Ammonia to lower the Ph. in the soil but that can lose its effects over the years with weather, but iron nails tend to last a lifetime..

Nice. Unfortunately I never went to any of those places during my days at the U of W - at least that I can recall.

Organ pipes from Church down the road from where our camera club meets. Being Easter and that.

No other reason. Just felt like posting a pic.

Yes those Church organs can really play great sounds but it a pity they never get someone who understands them enough to not pulls out all of the stops, they usually sound frightful.
Very nice photo Roy..
