The drops are most likely microdrops from the sprinkler system. These microdrops can travel hyndreds of feet through the air. Unlike regular drops, you will never feel them.

Take a piece of glass and mist the air at a distance and probably above the glass. You will need to trial and error the distances and the air flow where you are doing it.
