One of the simplest ways we have constructed a wind tunnel baffle is to purchase some corrugated CorePlast which we then cut to the length we wanted and glued it together.  It works really well giving good laminar flow.

Hello,

We are looking for an inexpensive material to use as baffling in a 
prototype wind tunnel that we are building.  We are trying to build 
honeycomb with drinking straws or plastic corrugated material - very 
tedious and not all that successful.  Any ideas on ready-made 
honeycomb material that we can purchase?  It needs to be about 1/2 to 
1 inch thick with holes about 1/4 inch.

Thanks,
Anna
