A garbage bin installed next to a bus stop in Jerusalem applauds those who use it. Drop a piece of trash in, and a recording of a child’s voice says, “Thank you very much!”. It’s part of an initiative by local residents to clean up the streets in the Pat neighborhood of the city. It is silent on Shabbat.
