Rub some Frog's Fanny (or hydrophobic Cab-o-sil) into the dubbing of
your spinner or soft hackle or whatever fly you're using. I think it's
best to do this before tying in the dubbing, but it probably works OK
with already-tied flies. Since this fine powder is hydrophobic
(repelling water) it promotes the formation of bubbles.

However, this will make an unweighted fly float like a cork, so you may
have to weight the fly to get it under the surface film.

Attracting air bubbles is exactly what I am
after. *Thank you!

Seems to me if cast it up into the rapid and give it
a swift tug, I could force/trap it under the film. *Thus
achieving the strobe light effect I am after.

I will have to test this out. *Guess I will
just have to go fishing! *:-)

Another thing you can try is dip the fly in RainX (used on car
windows) and let it dry. This will also make it hydrophobic.
Another technique is to "make" a bubble using LaFontaine's sparkle
pupa technique (http://www.westfly.com/fly-pattern-recipe/wet/
sparklepupa.shtml).
