After a downpour in Cambridge Springs, Pa I found this odd Lawn Bubble in my back yard. So strange but interesting. Contrary to popular belief. This is all natural, no membrane, no septic, and no broken water line. It was back to normal by evening. it happened in May of 2015 and has not happened since to my knowledge. I just could not resist popping it. “To use this video in a commercial player or in broadcasts, please email [email protected]”
