Picture of 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

We created this for our 8th grade science classroom. It is 10 feet long and made out of 2" foam insulation. Fantastic...

Thank you.

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

Cool! How are you making your wings!

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
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.
