I am in sort of a critical bind: I've been working for several months on an ISEF entry as part of a class (actually, working on the project IS the class), and in the past week it has completely fallen apart -- I won't go into details, but there is absolutely nowhere I can take the project. However; I can't drop the class. Whether or not the project actually does well in ISEF, I still need to have an entry in order to pass the class. SO. I have found a new general area, Bridge Aerodynamics, in which I want to start a new project, but here's the catch: I need to have experimentation up and running in about two weeks, or less. I have access to an extremely well-equipped wind tunnel at the University of Kentucky (they have already agreed to let me use it) and a LOT of spare time, but I am still wracking my brains trying to come up with the actual project. Can anyone recommend to me some way to narrow in on a project? Or some previously performed experiment that I could use as a springboard, possibly modifying or improving on old research? I am willing to put in a serious amount of work on this, I don't want bare minimum here and I'd really like to make it impressive, but I hope it could remain within some reasonable parameter of difficulty (high school senior).
