Well, I've got a pretty good idea for what my experiment will be now. Thanks to everybody for all your advice. I'm going to look into pressure probes and other ways of measuring force at different points around the towers. It's just a small science project, so I'm not required to get extremely...

Yes, I see now. :) What if I mounted graph paper behind the towers, then attached long strings to the sides of the tower to see how they move in the wind? I could film this on my camera and slow it down to view the distance the strings moved, or I could dip the ends in ink or paint and...

This is where I'm uncertain how to proceed. I'm not very familiar with drag and aerodynamics, and the research I've done seems to indicate that to find drag, the object in question must be moving. My towers are going to be stationary.

Okay, I've done some more research and I was thinking I could perhaps calculate the drag behind each object. The problem is, all the equations I've found seem to be very complex and require velocity to find the drag. Is there a simple way to find this? The wind tunnel is not very complex. It...

For a school science project I am supposed to design an experimental process that utilizes the wind tunnel my school owns. I've built four small model towers out of wood - one a triangular prism, one a rectangular prism, one a cylinder, and one a pyramid - that all have the same height and base...
