Thread: wind tunnel/ science fair question

For my science fair project, I am going to be constructing a wind tunnel that measures lift. I was wondering if anyone had any ideas for a good wind tunnel and/or a good power source? I thought maybe for the wind tunnel I could use a drainage pipe but I'm not sure. Furthermore, I think the conventional household fan will not be powerful enough- a leafblower maybe?

THANKS!!
