What’s a record player? (Joke.) That would be great… And you could actually have students calculate the RPMs by using the clock they tend to stare at as the class starts coming to an end… AND HYPNOTIZE THEM as they counted how many times a little action figure passed by!

Hm. I wonder what the thing I’d most want my class to do if they were under hypnosis is… It would probably involve taking better notes or writing their homework more neatly and carefully and show all work. Or bringing me a donut every day.

Enough rambling. It’s been a long day; I’m loopy.

I’d be tempted to bring in an old record player (DJ K?) and set it up under my document camera for the angular velocity lesson.
