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
<p>Big Baneser how much cardboard did you use?</p>
<p>We created this for our 8th grade science classroom. It is 10 feet long and made out of 2&quot; foam insulation. Fantastic...</p><p>Thank you.</p>
Could you make this out of wood???
Nice I am doing a science fair project on wing types and some of your info really helped inspire me
<p>Cool! How are you making your wings!</p>
Out of quad paper
dude u could put a hole in the bottom and vook it up to a vent so that warm or cold air be directly blow on you
i'll make a small one with a PC fan<br>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.<br /><br />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.
