sure. how would you go about doing that?
Hi again! Sorry about the delay in responding. Sometimes I can't get on for a whole day and the thread's already three pages longer. ; )
First off, don't sell yourself short. Taking a step back and thinking about what you're doing is /good/, but don't ever think that you're not important enough to make a difference. The fact that you are thinking, and that you are willing to think about test design, and that you really want to research this, indicates to me that you're certainly important enough.
As for designing a protocol, you just need to sit down and think about all of the things that /could/ be going on (like air currents, vibrations, static electricity, etc) and then think of a way to isolate your test target so that those things are shown not to be a factor.
You've gotten some really good suggestions from people: I think that the idea of using a ping-pong ball is excellent, but I think most excellent of all (if you can't work through glass or plastic very well) was CLD's suggestion of using multiple pinwheels and trying to move just one.
Lastly, remember that you shouldn't give up just because you feel overwhemed here. People are going to be hitting you from all different directions with all kinds of observations, suggestions, criticism, etc. The most important thing about all of it is this: anything that has a measurable effect on the world is testable in some way. Nothing else anyone says here is important.
