I can't believe there aren't any web photos or videos of people doing this... I'll have to make some!
Stand by.
We need videos for sure. It's part of cycling tradition and should be recorded for posterity. I can still picture in my mind a whole pace line doing this in nearly in sync several times on every ride.
Right hand -- unless you are left handed...
I do it behind the seat tube, a few inches in front of the rear brake bridge. Brush lightly, pointing down and forward. If they catch glass it will feel like gravel stuck to the tire. If it doesn't come out in a couple turns, pull over and dig it out. Sometimes glass will dig itself in very quickly, but many times you can get it before it punctures the tube.
