How Can I Get Access to These Seminars?

A listener came up with a brilliant idea while visiting his grandmother in the hospital. A respirator mask sealed over her mouth and nose, making conversing nearly impossible. He realized that if he took the mask home he could buy a pretty cheap microphone to install into it. We'd love to see them in classrooms across the country. They might be a good substitute for a book for a monthly book group or even just I don't know, disburd dinner conversation if you've got a weird intellectual family.
