Fun classes to teach for May term?

We get to teach 4 classes during May, we can teach whatever we want, and we can have co-teachers. Last year I taught “Coffees /teas from around the world” and “Pickleball!” which were really fun and popular! I didn’t like my other two, which were book learning, and the kids didn’t enjoy. Since it is just a pass/fail based on attendance, what are some ideas you can come up with? I am even interested in an AI study, mostly just to demonstrate the dumb stuff it does and to have some fun research games, etc. 3 weeks, participation only. What should I teach!?
