Question
My son is doing a science fair project with the question of: Does the shape of a wing on an airplane affect the lift. We have made a wind tunnel out of plywood, plexiglass, styrofoam and straws (vents) but we are left clueless on what to do from there. I have contacted his teacher tonight several times to no avail. It tells us to tape a trash bag around the larger (plexiglassed) end and to stick a vacuum hose through it but does not say what we are to do from there. If there is anyway you can help me I would greatly appreciate it. Thank you

Stephanie

Answer
Stephanie,

I hope you understand but I really will have a hard time answering your question without seeing the instructions you've followed thus far....

I have to go out of town now and thus will not be able to follow up on this in a timely manner...

Sorry and hope another on the panel of aero types can help you out...
