I've never heard of a wind table--is that like air hockey? http://www.flickr.com/photos/dubster/3474778695/
Why have no not commented on my cycling wind tunnel thread if this is so easy?

What exactly are you trying to test? wind tunnels are typically designed to test aerodynamic properties by testing drag of airfoils etc. so laminar flow is critical because if the tunnel creates drag you won't get an accurate measurement. If you wanted to see how sand blew around, a wind table is what you need.

I'm looking for a small-scale wind tunnel at UND or somewhere in Grand Forks that we could use for some geology (geomorphology) experiments for a class. We'd like to blow some sand around an object and be able to measure certain aspects, and apparently it's not "wind-tunnely" to just set up a box fan because you don't get reproducible laminar flow.
If anyone has any ideas, drop me a PM or post here.
