I did a three minute interview on the top TV station in Vermont, during which I did a variation of the collapsing can demo.

I thought the interview went well. I lost sleep over whether I could get the can to collapse during the live interview.
I talk a lot more about using the demo to teach about gases, kinetic molecular theory, the unified gas law, and using student writing to help students develop ownership of chemistry concepts in the book Notes to a New Teacher.
