Since I have to be at a meeting on the afternoon of Tuesday, Sept. 11, I've recorded notes & instructions for the demos and posted that here. Hope your class & quizzes go well!
Note: Yeah, I know I messed up on describing the two outcomes of the first demo. Cut me some slack, Jack. Also, there was fly in the room when I was recording that become increasingly annoying throughout the video. That should be entertaining for you.
Bonus? If you missed any of this you can go back & re-watch. Or, if you didn't quite finish before it was time for the quiz, you can watch at home. :)
