Cardboard Wind Tunnel

In this instructable, which happens to be my first, I will show you how to make a working wind tunnel using only a few easy-to-obtain materials. It only takes a few hours to make, and can generate high enough wind speeds to easily lift up a styrofoam airfoil. I built this to help me with my science fair project last year at school, in which I tested to see if different airfoil designs would generate more lift than a regular airfoil. Anyway, here's the Instructable.

Step 1 Materials and Tools

All you need to make this wind tunnel are the following items:

-  cardboard
-  duct tape
-  cardboard mailing tubes
-  box fan
-  glass or plexiglass (about 8" by 8")
-  scissors
-  hobby knife or box cutter
-  tape measure
-  hot glue gun w/ glue sticks
-  saw

i'll make a small one with a PC fan
but nice idea with the cardboard tubes, simpler than honeycomb

Very nice. Do you have a video of it working? It would be cool to see some airfoils floating inside of it.

Also... "Congradulations!" should be "Congratulations!"

No, I don't have a video. I have a picture of an airfoil in it, though. I'll see if I can attach a picture to a reply soon, but I don't have the picture on my iPod touch, which is what I'm typing on now.
