Other than for topology students in grad school, where is the mathematics in exploring mobius strips and hexaflexagons?
Mobius strips and hexaflexagons are great "gee wiz" activities, but I wonder if they are on the same order as baking soda/vinegar volcanoes (don't teach much except possible misconceptions). I'd like to put together some activities for facilitators to do with visitors on the museum floor, but I want to be able to answer the facilitators when they ask "why is this Math?"
If you dare to answer my question, add the word "so?" to your explanation and continue until the "so?" question no longer seems appropriate.
