I'm not sure how much running water the barley straw (in a plastic ball
holder) got in my teeny water garden, but it seemed to be collecting "gunk"
quite well before my dog discovered that the holder made a good dog toy --
it only took her a day or so to teach me to "fetch"

Good place, since straw needs running water to work properly.
