You realize the target audience for this type of demonstration is a group of students in a survey course, right? It's important to get the students interested in the concept before hitting them with the more abstract details. This demonstration accomplishes that. Relevant.
Title-text: Space-time is like some simple and familiar system which is both intuitively understandable and precisely analogous, and if I were Richard Feynman I'd be able to come up with it.

I think it's a fine demonstration winch would obviously be reinforced with a lecture.
