An alternative to the 'water in a pipe' analogy.  Might could help students trying to visualize the unseeable.  If nothing else it's fun to watch.

I don't have a good alternative to pressure and flow, however I do recall feeling an electrical shock made me develop a better understanding that what was there is real, not just a concept. One could argue watching a fan rotate is proof enough, but feeling the shock was more of an "ah ha" for me.

BTW in my case it was the spark plug on our lawnmower. You can imagine it left quite an impression. I do realize that would not be appropriate in an academic setting :slight_smile:
