Science Buddies: "Ask an Expert"

I need a basic design to build a small windtunnel to test the aerodynamics on vehicle spoilers. Any suggestions, designs, etc
looking for links on spoiler design

Where are you located? If you are in the San Francisco Bay Area, there is a lab run by the Sysnopsys Outreach Foundation that has a low-speed wind tunnel that might be what you need. If you live in the area, we can discuss the use of this lab's equipment further.

Depending on how small you're thinking, you could build one around a fan like this: http://scientificsonline.com/product.asp_Q_pn_E_3082394

I googled "how to build a wind tunnel" and found:
