Car Auto Design

Walking by the Berczy Park fountain I noticed some bubbles along the sidewalk and in the road. I followed the trail back to the fountain and, aha, found the source. Someone, or something, had placed soap in the water and like a big washing machine the churning water had soon created a cloud of bubbles.
This also happened in 2008 and 2009. I don't believe in coincidence so I think it is just someone, probably a broke University student, doing their laundry - once a year.
