Now, can you explain to the class what effect sticking this tape to
"just about anything else you care to stick it to," is going to
have on drag?



Well, the dimples form a very shallow turbulent layer that
paadoxically aids in the adherence of the boundary layer to the
surface thus reducing turbulence and as a result, drag as well.


So if I stick this on my propeller (or "just about anything else you
care to stick it to," ) I am going to reduce drag?



Apparently. I have an article about it somewhere. the prop installation
was problematic and not STC'd for certified aircraft. It tended to peel,
apparently. They were featured in Sport Aviation a few years ago.
