Post 59: "Die Fledermaus" with the Männerchor

Today, I started a run of 28 tests on the mixtures that I made a month ago on the Rheometer.  We needed to see at which temperature they foam which means that the reaction was going on and releasing gases to cause bubbles to appear.  I got through 9 of them today.  After this, I went to the men's choir rehearsal.  We sang the "Brüderlein und Schwesterlein" from Johann Strauß "Die Fledermaus".  It was a lot of fun.  We then sang a few other folk songs, and two american spirituals;  "Go Down Moses" and "Deep River".  I'd never rightly heard either of them, but it was a lot of fun to sing them.  Then I got to explain to somebody what the term "chillin' " means.
